Earth’s the right place for love:

I don’t know where it’s likely to go better.
I’d like to go by climbing a birch tree,
And climb black branches up a snow-white trunk
Toward heaven, till the tree could bear no more,
But dipped its top and set me down again.
That would be good both going and coming back.
One could do worse than be a swinger of birches.

Excerpted from Robert Frost – “Birches”

white birch grove

White Birch Grove

Preparing to write about these lovely deciduous trees has been quite a journey.

I have found that what I know is only the tip of the iceberg of what I need to know.  The White or Paper Birch is a tree that I am slowly becoming familiar with. My early relationship was one of taking for granted that this tree would always be here for me to sing to, climb and use as crafting materials.  I did not ever imagine these lovely fast growing groves of trees could be used to heal, attract some of the most powerful healing fungi in the world or that they would one day be imperiled.

My father was a land surveyor and he sometimes took me and my siblings along for the day on his forays into the forested areas of Oregon. On a early summer day many years ago he took us on a walk along a coastal mountain stream.  The White Birch was plentiful and lovely.

We came upon a White Birch which had a broken branch half hanging.   He took some of the sap dripping from the broken tree, spread it over the wound, and then he took the shedding white bark for which it is known and used it to tie the branch back in place.   This is just one of the “signatures” of this tree.  Later I would learn that birch bark was used to set into a cast, the broken bones of humans.  On that day long ago, my father gave me some of the sap to chew and told me that it would be good for my teeth and mouth.  It was sweet and tingled in my mouth. I asked daddy about the bark.  I asked if I could remove some naturally occurring shedding white bark without white birch hanging barkharming the tree.  He told me that in other parts of the country, the bark was used to make canoes and to line baskets and wrap food and that it had probably been used as paper somewhere in the world. He told me there was time of year in the late spring and early summer when the bark was easy to remove without harming the tree.  He told me the tree sap was very healing as was the bark and that is why he used it to repair the broken limb.

Later I used some of the bark to make clothes for my doll and I made a small pouch to hold special things.  I made a small canoe that I could push across our pond.   I found sanctuary in the birch grove and sat in silence to watch the wild birds skip from branch to branch.  In late summer the tiny rounded samara became part of my secret cache of wild seeds.

This was my introduction to White Birch.  It was easy to interact with the community of birch. I can imagine now that it is this easy relationship to the tree and bark that attracted the First People. It is also easy for humans to take this tree for granted, not respect it.  As you will read, the White Birch is a powerful healer for both human and forest communities. It is a tree that welcomes the fungi mat (mycelium) and heals the wounds caused by fire, humans, disease and floods.

Betula papyrifera (Paper Birch, also known as American White Birch and Canoe Birch) is a species of birch native to the northern part of North America and the southern part of Canada.  The species birch is found all over the world.

PREPARING THE WAY – Birch, Alder, Aspen

Some trees are steady and slow in growth reaching to the tops of forests they create an umbrella for the web of life.  And, some trees are pioneers, growing fast, living a short time and creating a birthing platform for many other species. The White Birch is a pioneer species. The stands of White Birch come on fast and can grow only to about 20 meters high (65 feet). A healthy tree can live to be 40 or 50 years old. During their growth the pollen from birch catkins attract a great many pollinators that will bring life to other plants in the forest. The sap and bark attract a great many fungi that live symbiotically on the tree.  The fungi are then dispersed into the disturbed soils to help create the forest mycelium mat.  For a long time scientists and foresters thought the fungi found on the birch were a sign that the tree was dying.  They thought the fungi were killing the tree.  Now we know that the birch is a nurse tree to a great many beneficial fungi. It chooses which fungi will inhabit it and also has a chemical defense method that will trap certain fungi in the heartwood or on the outer barks.   The sap actually has pesticide qualities.  It detracts insects such as termites and certain bacteria that might do the tree harm. According to Grieve in her book A Modern Herbal, Birch tar was used to repel insects (p. 103)

Like the Red Alder and Aspen, the White Birch lives in symbiotic relationship with nitrogen-fixing bacterium.  This relationship is called mutualism. In mutualism: plants gain nitrogen compounds, the bacterium gains carbohydrate and an environment with reduced oxygen. The plant then changes carbon dioxide to oxygen and releases it for human use.

White birch as a pioneer deciduous species is often found in groves on the edge of newly formed second-growth tree communities or near the edges of changing forests. This tree shows up in ecosystems that have been disturbed by fire, flood or human decimation.  They can be found in open or dense stands of forest usually in an opening. They can be found in lowlands to lower mountain slopes in drained sites or along bogs and other wetlands.  B. papyrifera requires high nutrients and sun exposure.

These trees do not live long. From the time they spring up and then die, can be as little as 20 years or as much as 50 years. It is easy to propagate and the young saplings are often found spouting from a cut stump.  Like the Red Alder, the White Birch is a very important part of establishing the mycological forest community. Without these forerunners of forest health, there would not be a fertile soil and microbiological environment that would support the deep wild forest.

NAME

The name is a very ancient one, probably derived from the Sanskrit bhurga, ‘a tree whose bark is used for writing upon’ (Grieve, p. 103).  The First Peoples of the Cascadian bio-region have names for this tree also:

Salish = âîçêáÛ – birch bark

âîçêálî, îçêá white birch, paper birch, birch bark.

paper birch îçæálî, îçæá birch; paper birch.

The English name is White Birch, Paper Birch or Canoe Birch

The Latin botanical name is: Betula papyrifera

LEAF

white birch leafThe leaf is alternate, deciduous, oval to round and sharp-pointed. The leaf of the White Birch can be longer when on young trees. The color is dull green above and paler and hairy below.  The margins are doubly toothed. (Pojar and Mackinnon p. 47)

Learning the shape of the leaf is important because there are other trees that grow in similar environments that look much the same when young.  For instance bitter cherry has a similar bark and structure but the leaf is oblong to oval, and less pointy.

The FLOWER AND THE SEED

The flowers, and thus the seeds, of white birch are arranged in a pendant cluster about an inch long which is referred to as a catkin. Male white birch leaves-catkins-conesand female flowers are on separate catkins. When pollinated, the female flowers develop seeds, each of which is located on a scale in the catkin.

Male and female flowers grow in separate catkins and flower at the same time.  Sometimes there will be young leaves emerging as the tree flowers. The buds for the male catkins appear in autumn, when it begins getting cold.  During spring, the tassel-like catkin will produce yellowish or grayish green flowers that produce pollen with an aromatic scent.

Over the winter the catkins disintegrate, dispersing both seeds and scales.  You can identify the species of birch from the shape of its scales or nutlets.  Again, the white birch nutlet is round with wings that are broader than the body.

The male catkins will fall away from the tree, while the female catkins will form into cones in the summer. These cones vary from a deep brown to a tan, though they may also have a reddish color to them. During late summer, the cones will open and in autumn, the cones will fall, spreading their nutlets across the ground. The nutlets are then dispersed on the wind.

BARK

The tree is most familiar to us humans because of its bark.  The bark peels in papery strips in late spring and early summer. The bark of this tree is commonly thought of as being white or grayish white, but also comes in yellowish or dark gray.  It is often marked with brown horizontal lines of raised pores. The bark is highly weather-resistant. The wood itself is highly flammable and can be burned as firewood even when damp.

MEDICINE

Birch syrup is a sweetener made from the sap of birch trees, and used in much the same way as maple syrup. It is also used as medicine syrup.  The sap is boiled down to produce birch syrup.

The same sap is fermented to make beer and wine.  Birch beer is very popular in Northern Europe and a few areas of North America.

The oil is astringent, and is mainly employed for its curative effects in skin afflictions, especially eczema, but is also used for some internal maladies. Oil of wintergreen is distilled from its inner bark and twigs (Meyer p. 15)

The inner bark is bitter and astringent, and has been used in intermittent fevers. The bark is ground to a fine power and used to treat diaper rash.  It is also used internally to treat a great many inflammatory and bacterial infections.

The vernal sap is diuretic. The resin contains zylitol, a disinfectant used as a natural tooth cleaner. However, it may also contain terpenes. Used in making turpentine, terpenes and terpenoids are the primary constituents of the essential oils of many types of plants and flowers. Essential oils are used widely as natural flavor additives for food, as fragrances in perfumery, and in traditional and alternative medicines such as aromatherapy. It was also reported that those who chewed the resin could get somewhat of a “buzz” (Pojar and MacKinnon p.47.

One of the chemicals that has been isolated from birch bark is called betulin. Betulinic acid, which is made from betulin, is being studied as a possible cancer treatment. Betulin has also been found in many other plants.

White Birch is used on the skin to treat warts, eczema, and other skin conditions. Promoters say that birch tea can be taken internally as a diuretic or a mild sedative and that it can be used as a treatment for rheumatism, gout, and kidney stones. The leaves are sometimes used on the scalp to help with hair loss and dandruff. Birch tar (oil distilled from birch bark) is used on the skin for skin irritations and parasites. Other claims for birch bark include the treatment of diarrhea, dysentery, and cholera.

WHITE BIRCH AND THE POWERFUL FUNGI CHAGA (THE TINDER CONK)

White Birch Moxa

Before I started this study of the White Birch, I did not know that the First Peoples in Cascadia used Moxabustion.  Moxibustion is the application of heat resulting from the burning of a small bundle of tightly bound herbs, or moxa, to targeted acupoints on the human body. The burning plant material is traditionally mugwort.  It is sometimes used along with acupuncture.  It is used to open up or move energy in a part of the human energetic body. It is well-known that for thousands of years far-eastern cultures have used moxabustion as part of their healing regimes.  What I was not aware of was that the First Peoples of North America, Central America and South America also use Moxibustion.  As I studied the White Birch I came upon a quote that perked up my inquisitive nature.  The book is called A Modern Herbal published in 1931 by Mrs. M. Grieve.  Grieve reports that birch leaf and bark was used as a moxa, and that it was burned on top of a fungi.  Both the birch parts and fungi were used to create a moxa for healing. Here is a quote from Grieve’s published works.

“Moxa is prepared from it and regarded as an effective remedy in all painful diseases. A type of moxa is made from the yellow fungus that is excreted from the wood of the White Birch, which sometimes swell out from the fissures of the bark” – Grieve p. 104

After some research I found that there are several types of fungi that are yellow and live in the fissure of the White Birch.  It is a tree that attracts fungi as it ages. Here is short list of some of the edible and medicinal fungi that grow on birch.  Ganoderma applanatum, or artist’s conk, Oyster mushroom (Pleurotus ostreatus), Turkey tail (Trametes spp.) attacks fire-scarred, wounded and drought-, freeze- or sunburn-stressed birches. Hairy (T. hirsuta) and colored (T. versiclor) turkey tails, Lenzites betulina, commonly called birch mazegill, Yellow Brain fungus and Chaga (Inonouts obliquus). According to Paul Stamets, most of these fungi have several medicinal properties, including antioxidant, antimicrobial, antitumor, and immunosuppressive activities. (Stamets 2005)

There are so many fungi attracted to the White birch that I would only be able to identify which was used as a moxa by contacting an expert.  But, there are clues.  It is yellow; it is used for burning as a moxa.   Was the fungi Chaga (Inonouts obliquus) also called Birch Tinder fungus Grieve’s moxa?  Chaga has a somewhat yellow underbelly.

I found several books that stated that the First peoples burned plants for many reasons; healing, food, spiritual connection, and fire carrying. It is well know that the First Peoples of all cultures across the globe including those of Cascadia burned plants as a method of reconnecting spiritually to the natural world.  They smoked and burned plants for healing and for ceremony. And they used the burning of plants as a method of healing via moxabustion.  One method of releasing essential oils in a plant or bark was to burn the plant, or place it on burning material and let the spark ignite the essential oils of the plant.  This method was often used to help healing substances connect with hard to reach areas of the body, such as cartilage and deep tissues.  My investigation found that in the practice of shamanism, moxabustion was essential to the healing process.

Let’s look at Chaga and its relationship with the birch.

Many mushrooms prefer a particular wood for their growth because they need the nutrients and conditions that they can get from that wood. Some form symbiotic relationships with certain trees, as the chanterelle does with birch, but many also feed on dead, decaying wood. There are also mushrooms that parasitize birch trees and which will kill weakened trees, such as the birch polypore (Piptoporus betulinus), a shelf fungus with an interesting history.

Chaga, a fungus in the Hymenochaetaceae family is in a symbiotic parasitic relationship with birch and other trees. The sterile conk that is Chaga is irregularly formed and has the appearance of burnt charcoal. Chaga was called the Birch tinder fungus because it was used as a means of carrying fire from one hearth to another.  The fungus was lighted and it carried the ignition spark.  Chaga was also used as a moxa hearth.  Plant material was placed on top of a burning ignited Chaga.  Together the Chaga and the burning plant created a moxabustion of healing aromatic substances. According to Paul Stamets the First Peoples used these fungi as a natural antibiotic, anti-inflammatory, and immunopotentiator as well as a practical fire-starter mushroom. (Stamets – Mycelium Running p. 258)

Finally I found a research paper published in the Journal of Ethnobiology in the summer of 1992 titled “Short communication – Use of Cinder Conk (Inonotus obliquus) by the Gitksan of Northwest British Columbia, Canada.

The author Leslie M. Johnson Gottesfeld writes:  “Cinder conk had two principal uses: for moxibustion treatment of swollen athritic joints, and as tinder or a slow match for making and transporting fire.”

Further she writes the Gitksan elder had two words for cinder conk: mii’hlw and tiiuxw. A Gitksan elder describes cinder conk and its medicinal use as follows:

“Mii’hlw-the black growth from the crack in the birch tree. Like yellow cotton inside. If you cut it off, use the yellow cotton stuff. Take a sliver like a match stick and burn it for pain in the joint.” According to the elder, after the sliver of cinder conk was burned near the skin on the affected joint, a special salve was then applied to the burn wounds. This treatment was reported to be effective in reducing the swelling, and presumably the discomfort, of the joint. ( Johnson Gottesfeld p. 154-55)

I love this much endangered fungi and birch that it grows upon.  And so do others who value it for its healing abilities.   Paul Stamets reports that wild harvesters for the nutraceutical industry are decimating the White and Yellow Birch populations of North America and Europe as they walk through the forest with machetes chopping the fungus off the tree and causing life-threatening damage to the trees.  The removal of the mother-chaga is also removing the spores from the forest (Stamets, October 2012).  The Chaga communities are becoming rarer as are the birch forests.

Stamets is trying to remedy the situation by teaching the nutraceutical industry and others to grow Chaga in growing houses on birch and other forest product chips.  He is also asking that the industry stop buying from foragers. Here is a link to a short video about conservation efforts to save the Chaga and the birch.

The trees are dying for a second reason:  Birch trees are especially sensitive to herbicides because they have a shallow root system. The herbicides are also decimating the beneficial fungi that live in symbiotic relationship to the birch.

UTILITY – CANOES AND BASKETRY

The White Birch is also called the Canoe Birch. In the Cascadian Bioregion (Pacific Northwest), some canoes were built as large as one

Canoe building - inland waters of Pacific NW

hundred feet long and seven feet wide, and could hold up to sixty people. Bark canoes are constructed of sapling frames covered in bark. Birch bark is very popular for both its durability and its relatively light weight. The birch bark is an outer covering spread over a frame (ribs and gunwales) made of flexible wood such as red or white Cedar. The canoe of the First Peoples was extraordinarily light and graceful. When new and dry, a 15-footer might weigh less than 40 pounds; the longer ones, made by some tribes, weighed about 75 pounds. One man could pick up a canoe and carry it, upside down and resting on his shoulders, over a long rough portage. For its size and weight, it had greater carrying capacity than almost anything that floats. A birch bark canoe could carry almost a ton of load and it is said that a 15-foot canoe was often used to transport an Indian Family with several children, plus all of their duffel and dogs. (Nature Bulletin)The Birch bark has been used to make baskets for thousands of years. There are myths about these baskets that have been retold to the basket-making societies. The birch basketry was used to make many helpful containers.  Panels of bark were also be fitted or sewn together to make cartons and boxes (a birchbark box is called a wiigwaasi-makak). The bark was also used to create a durable waterproof layer in the construction of sod-roofed houses.

Red Alder (Alnus rubra)

During the storm I dreamt of Red Alder.  I dreamt that the spirit of the tree was leading me away from danger.  Then I woke and saw ruts of the big machines and I cried for the forest.  Soon after the Red Alder came up through the sun-baked soil of the clear-cut. – Ellen O’Shea – Radical Botany

Red Alder Grove along stream

Some plants are trailblazers.  They show up when great change has happened.  They grow in the ruts of human civilization, the mud, the flood tracks and the places where sun and wind prohibit other plants to grow. Red Alder just such a trailblazer. A true pioneer plant.  It shows up to heal, grows fast, stays a short time, then allows the tall conifers, the redcedar and majestic Bigleaf maple and other trees to take over.  It is a friend and healer of the forest. It is a tree that perseveres in the direst of circumstances. Even after massive clear-cutting and wild fire destruction where the forest seems changed forever, the Red Alder will push up out of the graves of other trees and change the soils.  It is an alchemist.  It will attract the bacterium needed to change the acid of riddled sun-parched soils into  the conditions needed to bring back an entire eco-system.  After the Red Alder emerges, the tiny herbs, the ferns and sedges follow.  Soon after that the wildflowers, elderberry shrubs, Indian plum and wild honeysuckle will follow. And then the conifers and larger deciduous trees follow and a whole forest eco-system emerges.

The Red Alder soothes the hardest of earth and entices the fungi, bacteria and nutrients back into the forest floor. The bacterium on its roots fix the nitrogen needed to feed the forest community. A grove of Red Alder will only live about 100 years, just enough time to coax the forest community to come home one more time.  As a healer of humans its bark is used to sooth the acid stomach and gallbladder, clean the lymph glands and bowels, entice the poisons from the skin and open up the lungs.  A poultice of the bark will bring forth the inner poison.

Red Alder wood chips are often used to cultivate eatable and medicinal mushrooms such as the Shiitake.

THE NAME

Clallam  – s’ko’noiltc

Quinault – malp

Swinomish – su-k’uba’ts

Alder is the common name of a genus of flowering plants (Alnus) belonging to the birch family Betulaceae. The English name was derived from the bright rusty red color that develops in bruised or scraped bark. The outside bark is mottled, ashy-gray and smooth, often draped with moss. But just inside is the glorious red used for dye and medicine.

HABITAT

Red alder (Alnus rubra) are the largest species of alder on the west coast of North America.  The tree can grow to 40 feet or more, needs full sun, is a nitrogen fixer, tolerates poor, wet soil and is found in valleys in the Cascadian bio-region as well as the foothills of the Cascade Mountains. Red alder is a fast- growing but short-lived (old at fifty, with a maximum age of about a hundred years).

For years, as the rain forests of the Pacific Northwest were devastated by massive clear cutting of the region, Red Alder was thought to be invasive and was destroyed.   For the first 100 years of European settler decimation, the Red Alder was thought to be scrub, a noxious weed and unnecessary for forest health.  Then in the 1970’s and 80’s as second and third growth Douglas fir tree farms failed to thrive, research showed that an essential part of the forest eco-system was missing.  Red Alder, an amazing nitrogen fixer had been systematically removed from the forests using massive amounts of chemicals and extraction methods of forest management.

With the lack of nitrogen in the forest soils, other native species began to be stunted and attract disease. But as foresters began to study forest re-growth, they noticed that Red Alder was one of the first trees to return to a clear-cut.  They also noticed that as the Red Alder stands thrived, so did the small plants, shrubs, and then other tree species thrive. The Red Alder is a forest healer; it brings life back to much damaged soils.  For soils that have been heavily sprayed with toxic chemicals, the introduction of Red Alder is less successful.

RED ALDER AND NITROGEN FIXING BACTERIUM

An important nitrogen-fixing bacterium in our Cascadian bioregion is Frankia ahni.  Red Alder (Alnus rubra) and other types of alders are the host for this important bacterium. Alder is particularly noted for its important symbiotic relationship with Frankia ahni, an actinomycete, filamentous, nitrogen-fixing bacterium. This bacterium is found in root nodules, which may be as large as a human fist, with many small lobes and light brown in appearance.

I found a great online source for explaining the nitrogen fixing process. “A Nitrogen Fixation: The Story of the Frankia Symbiosis by Peter Del Tredici a Harvard researcher can be found at this link: http://arnoldia.arboretum.harvard.edu/pdf/articles/1995-55-4-a-nitrogen-fixation-the-story-of-the-frankia-symbiosis.pdf

Here is a quote from that document:

“Before atmospheric nitrogen can be used by plants, it must be “fixed,” that is, split and combined with other chemical elements. This process requires a large input of energy and can occur either biologically, within the cells of various bacteria, or chemically, in fertilizer factories or during lightning storms.

Among all living organisms, only bacteria have evolved the complex biochemical mechanisms required for nitrogen fixation. All “higher” plants and animals that are said to fix nitrogen are really only the symbiotic partners of the bacteria that do the actual work.”

Red alder is often found growing near coast Douglas-fir (Pseudotsuga menziesii subsp. Menziesii), western hemlock (Tsuga heterophylla), grand fir (Abies grandis), western redcedar (Thuja plicata), and Sitka spruce (Picea sitchensis) forests. When found along streambanks it is commonly associated with willows (Salix spp.), red osier dogwood (Cornus stolonifera), Oregon ash (Fraxinus latifolia) and bigleaf maple (Acer macrophyllum).

Red Alder leaf

THE LEAVES

Alternate, deciduous (fall off the limb in the autumn), broadly elliptic, and sharp-pointed at the base and tip. The leaf top is dull green and smooth, and the underside is golden-colored and hairy. The leaf margin is revolute, the very edge being curled under, a diagnostic character which distinguishes it from all other alders. The leaf turns yellow in autumn before it falls from the tree.

 

The male and female catkin

THE FLOWER

The flowers are catkins with elongate male catkins on the same plant as shorter female catkins, often before leaves appear; they are mainly wind-pollinated, but also visited by bees to a small extent. These trees differ from the birches (Betula, the other genus in the family) in that the female catkins are woody and do not disintegrate at maturity, opening to release the seeds in a similar manner to many conifer cones. The catkins form in the fall, and then overwinter, ready to open or flower in spring. The female catkin is cone-like, droops slightly, usually in clusters of threes.

The male catkin is slender, cylindrical, hanging in clusters of 3 to 5 from short leafless branches.

THE FRUIT

Red Alder cones or fruit

The fruit is clusters of brownish cones which are quite small (up to 2 cm long). They remain on the trees over the winter and contain oval winged nutlets. About 2000 seeds are normally produced by the cones which are normally spread by the wind but also by the water and birds. The seeds have a viability of about 45%. Seeds are normally dispersed between the months of October and March.

THE BARK

The bark is thin, grey, and smooth often with white patches of lichens.  The bark will turn bright red to rusty red when cut.

As a weaver I often sought the bark of the Red alder as a source of dye.  I peeled back the bark and exposed it to air and it would turn a brilliant red.  As the bark dried the color of the bark changed from red to a slightly golden brown.  I fixed the color using apple cider vinegar.

MEDICINE

Red Alder is a bitter and an astringent (Meyer p.3).  Bark twigs and buds were used. An ointment of the bark was used to cure eruptive skin diseases (Stuhr  p. 21). Catkins are edible and high in protein, but are very bitter in taste and utilized usually on for survival food. The wood is used to smoke cooked food.

The Bark of the Red alder contains anti-inflammatory salicin that metabolizes into salicyclic acid in the body.

Cut of the Red Alder – new (red) and old (golden)

Salicin is related to Aspirin. Red Alder bark is used for relief from poison oak, insect bites, and skin irritations.  The Red Alder bark is used in infusions to treat lymphatic disorders and tuberculosis.

The bark was boiled and drunk for colds, stomach trouble, and scrofula sores. The rotten bark and woody parts were rubbed on the body to ease “aching”. (Gunther p. 27)

The wood was used to make canoes, boxes and paddles and multiple other utility implements.  Like the Western Red Cedar, this tree was widely used by the first people of the Cascadian bio-region. The wood was important because it could be used while still green, seasoned and not split in the sunlight.  The wood of the Red Alder has long been used to smoke salmon.  The bark was used to line baskets for storing wild berries, roots and other foods and herbs.

POLLINATOR AND BUTTERFLY HABITAT

Alder leaves and sometimes catkins are used as food by numerous butterflies and moths. The late winter and spring catkins are beneficial to more than one species of bee,  and depending on nearby habitat may attract other insect pollinators, such as butterflies, hoverflies, and pollinating beetles. If the Red Alder is close by water, the pollinators can be plentiful.

Red Alder is a better butterfly host plant than the Asian butterfly bush, which only provides some nectar, not structure to attach chrysalis, nor leaves for caterpillars after hatching.

If you would like to learn more about native plants and the pollinators they attract, order the wonderful book  put out by the Xerces Society called “Attracting Native Pollinators”.  The book is coauthored by four Xerces Society staff members Eric Mader, Matthew Shepherd, Mace Vaughan, and Scott Black in collaboration with Gretchen LeBuhn, a San Francisco State University botanist and director of the Great Sunflower Project.  More on the book go here – http://www.xerces.org/announcing-the-publication-of-attracting-native-pollinators/

Part one:  Conifers

A few minutes ago every tree was excited, bowing to the roaring storm, waving, swirling, tossing their branches in glorious enthusiasm like worship. But though to the outer ear these trees are now silent, their songs never cease. –  John Muir

As a young person I developed a deep love and bond with trees.  I spent hours climbing trees, swinging in the boughs of a large fir or sitting high in an oak tree.  I loved the ability to see long distances across the landscape.  I found many interesting things in trees.  Bird nests, ferns, nuts, acorns, mistletoe and insects all fed my imagination. I found incredible peace in the treetops.  I would have been very happy to have lived in a tree house.

So now I teach you what I know about trees.

I have spent months now teaching you basic botany.  I have focused on the parts of the plant.  I want to begin to teach you how to go into the forest and find plants. I will teach you about the trees first.  I will be focusing primarily on the trees found in the Cascadian bio-region-that area found from Northern California, through Oregon and Washington state and up through British Columbia.  The Cascade mountain range separates the Western regions from the Eastern Regions but mant of the areas share similar tree and plant communities.

There are of course some amazing micro-ecosystems found in Cascadia.  For instance the eco-system of Northern California and Southwestern Oregon are very different from the eco-system of Western British Columbia and Western Washington.  More on that later.

Trees have always been the marker that I use to find the plants I am seeking. Why?

Because I can look out across the horizon and see the tall trees, the old ones that will have the most to share as far as a finding plant communities.  For instance, when I am looking for wild orchids or lilies, I will look to the horizon to find a large Douglas fir old growth or a very tall Western Red cedar.

Trees are the anchor for plant communities.  They create habitat, keep plants fed and watered, provide shelter for pollinators and animals that carry the seeds throught the forest.  Large Douglas fir and Western Redcedar have an outreach affect that can cover miles of terrain.  The mycelium connected through the roots of big trees support thousands and thousands of varieties of plants. Communication between the species found under big trees has been studied and now documented.

University of British Columbia professor Suzanne Simard, has discovered through her research that “trees in a forest ecosystem are interconnected with the largest, oldest ‘mother trees’ serving as hubs”.  This research has found that all trees in dry interior Douglas-fir (Pseudotsuga menziesii var. glauca) forests are interconnected, with the largest, oldest trees serving as hubs, much like the hub of a spoked wheel, where younger trees establish within the mycorrhizal network of the old trees.

The research also found that all the forest plants had a much better chance of survival if they were linked into the network of old trees.  It was found that increased survival was associated with below-ground transfer of carbon, nitrogen and water from the old trees. This research provides strong evidence that maintaining forest resilience is dependent on conserving mycorrhizal links, and that removal of hub trees could unravel the network and compromise regenerative capacity of the forests. (Simard 2013)

There are two different groups of trees – conifers and deciduous.  Conifers are the evergreens.  And, deciduous are the trees that drop their leaves in the fall and re-grow green leaves in the spring.

THE 12 MOST IMPORTANT CONIFERS IN THE WESTERN CASCADIAN BIO-REGION – and how to identify them.

The trees I will be teaching you about are all found west of the Cascades.  Later I will make some charts of important trees found east of the Cascades but still in the Cascadian bio-region. The charts below include information about what the tree needle, cone and general shape look like. This information should help you identify them.  I have included information about wildlife that use the tree for survival and I have included ethno-botanical information about the tree.  I have created some graphs that you can print out and make as large as you like. They are stored as graphics on this web page.   I hope that you will print them out, take them into the forest and try to identify the trees as you walk. I hope that you will fall in love with the trees as I have.

“Beauty and seduction, I believe, is nature’s tool for survival, because we will protect what we fall in love with.”– Louie Schwartzberg, from The Hidden Beauty of Pollination

After I posted the first part of the “The flower in three parts” my current essay series, I received an email from someone who said “The Flower in three parts, sounds like a symphony”.  Yes, I said, that is the energy I have been trying to convey to others that botany, plants, native plants, flowers are all part of a symphony of life. Each part of the flower and its growth processes are important to the whole. The first part or movement was to turn your attention to this fantastic creation sitting at the end of a stem. I hoped to raise your curiosity.  I tried to flood your senses with wonder at the design and substance of flowers. It was a slow movement encumbered by way too much vocabulary but necessary if you are to truly meet the flower in all its wonder.

I have been drawing you into the allegro or opening sonata in order to capture your attention for the second movement the main allegro or scherzo: The pollination cycle or sex life of flowers. And finally in The Flower – part 3: “The Flower as Healer”, I will end with one of the strongest connections between humans and flowers: they heal us – the finale – we are flowers ourselves.  We are they and they are us. What we do to the flower, we do to ourselves. If we kill off the pollinators and clear-cut the plant kingdom, so goes all Eden, of which we are a part.

But now for Part 2: Pollination and The Sex Life of Flowers

The name of the second part “The sex life of Flowers” came from my research on flowers and their ways and means of pollination. While researching I

Sauromatum-guttatum-Voodoo Lilly

discovered a scientist named Bastiaan Jacob Dirk Meeuse.  He was a naturalist and botanist who was a professor at the University of Washington. He lived from 1916 to 1999.  Meeuse was a prolific researcher whose five decades of research on the exotic but stinky voodoo lily resulted in numerous contributions to science.  Dr. Meeuse was an authority on pollination, especially by insects and birds, and wrote the textbook ”The Story of Pollination” (1961).

In the 1980’s his research contributed to a well-known public television documentary called “Sexual Encounters of the Floral Kind” (1983). I have links to segments of the documentary in end of this essay. In 1984 Meeuse co-authored a book along with Sean Morris called “The Sex Life of Flowers”.

Meeuse was a botanist attracted by the exotic, he unlocked the secrets of the voodoo lily (Sauromatum guttatum) a relative of the corpse flower (Amorphophallus titanum). The voodoo lily has a very strong smell and generates much heat, up to 108 degrees when it ready for pollination. When it flowers, perhaps once a year, its fleshy purple spike emits waves of heat and an odor not unlike that of rotting meat. The chemicals released by the heat apparently helped to attract pollinators. (see picture).

Meeuse, along with his research team documented the flower cycle and the important relationship between pollinators and flowers. Meeuse and Morris found innumerable examples of mimicry in which the flower part has evolved to resemble a female bee. The male, trying unsuccessfully to mate with the flower, unwittingly collects and spreads the orchid’s pollen.

Here are a few facts about mimcry in pollination: When the male wasp tries to mate with the dummy female, he fails, but the orchid succeeds in getting pollen on the wasp. He flies away, only to be fooled again by another orchid pulling the same trick. In the process, the wasp transfers pollen from flower to flower. Plants that are farther away from each other are more likely to be distant relatives, so mimicry may reduce inbreeding. Posing as a sexual suitor may be a strategy that allows the geographic spread of plants over a wide area — generally, insects will travel further to find a mate than to find a meal.

Here is a link to the BBC documentary using some of Meeuse’s research:Wild Orchid and wasp mimicry – http://www.youtube.com/watch?v=-h8I3cqpgnA

Another important aspect of Meeuse’s research was to show that flowers develop MANY paths to pollination.  Flowers can be asexual (agamogenesis), hermaphrodites, only male or only female. And then there are the combinations. The only way to learn about a plant and its lovely flower is to sit with it, study it. Learn its entire life path. You just can’t make any broad statements about how flower reproduction takes place.

THE FERTILIZATION PATHWAY OF THE ZUCCINI SQUASH

Female and Male flowers of Zucchini Squash

Let’s look at the squash plant: A Zucchini squash plant has both male and female flowers.  Male flowers usually appear first and have a thin stem. Female flowers appear later and have a small, baby zucchini developing between the base of the flower and the vine. The male flower will usually open in the early morning, attract a certain type of early morning foraging insect, then can die away by the late afternoon.  The female flower will open later in the day and again attracts the same pollinating bee or insect and is fertilized by the pollen it is carrying.  If the small squash rots away then it has not been fertilized.  This can show a lack of garden pollinators. Hand pollination may be the only way to have a good crop of squash.

There is a very fragile dance going on here.  If there are no pollinator bees or other insects, our food will disappear. On most flowering plants there is only one short time frame in which a flower can be pollinated and if the conditions are just right or there are not enough pollinators available, no fertilization can happen. As in many processes in nature, timing is important. The female reproductive part of a flower is receptive to pollen only at certain times of the year. Creatures like insects and birds, which move from flower to flower in search of food, are a fast and often guaranteed way for plants to distribute their pollen.

Not all flowers need to be so cunning. Several angiosperm species including grasses bear inconspicuous blossoms – that use the wind for pollination.

Sometimes drought and disease can cause squash plants to only produce male flowers. Now this lack of fertilization can also be caused by severe weather change, or lack of fertilization in the soil types or pollution that causes mutations of plant or pollinator. Yes, the fragile dance is important to support.

PLANT CELLS AND THE MERISTEM-FLORAL

Floral-Meristem Physiology

For the last few months I have been leading you on a journey from the root to the stem to the branch and now on to the flower. All the while following the adventures of the meristem cell.  At the point of developing the flower, the meristem cell morphs into a meristem-floral cell and begins to produces cells that will become the structure of the flower.Plants produce 2 types of reproductive cells.  The first is the spore – found on such plants as ferns. The second is formed during sexual reproduction – a process where a population is divided into male and female members or distinct male and female structures on individual plants. The DNA of the plant, stored in these specialized flower cells will begin to build the structures and organelles that will become the flower. Flowers give rise to fruit and seeds.

BASIC SEXUAL PARTS OF A FLOWER

Flowers are short branches bearing specially adapted leaves, and reproduction is the sole function for which flowers evolved (Capon 2010).  Both the male and the female reproductive parts of a plant are in the center of the flower. The male, pollen-producing part is called the anther, held aloft by a stalk called a filament. The entire male apparatus is called a stamen. Each pollen grain is unique to its species. The female reproductive part of a plant, the stigma, sits on top of a style, or stalk, which leads to an ovary at the base. The entire female plant mechanism is called a pistil. This is the illustration of a perfect flower having both female and male parts (some do).

Flowers have figured out a way to do the amazing things they do while taking care of the place that will take care of their offspring.  They are focused on having their genetic material here 10,000 years from now. Plants seduce pollinators with fragrance, hue, platform structure and a promise of sex with another of its own kind and ensure return visits with the promise of nectar.

Some flowers attract with scent, some with color. Most offer nectar as an enticement to visitors and as a way to ensure repeat visits. The chemical ecology of plants seeks not only to attract pollinators, but keep predators away. The complexity of floral odors mediate interactions between flowers and pollinators to guarantee reproductive success (Carde and Ring 2004).

Return business is particularly important for plants that encase many seeds in a single fruit—raspberries, for instance, or melons. A poorly pollinated raspberry will have many shrunken, dry drupelets. A melon blossom that doesn’t attract enough pollinators may produce a melon that is small, lopsided, and not very sweet.

A few varieties of plants have adapted the shape of their flowers to favor certain pollinators—tubular blossoms attract hummingbirds, for instance, but the nectar is often inaccessible to bees.

Lady Slipper Orchid

Other plants aren’t choosy. They’ll do business with birds and bees, and also with wasps, beetles, rodents, and even humans if that’s what it takes to move the pollen.Many flowers have a distinctive bull’s-eye color pattern or a throat of a different shade from the outside petals, to help insects and birds find the payload of pollen.

Plant structures, too, are designed to attract specific pollinating partners. The Queen Anne’s lace flower places its nectar right at the base of its tiny flowers where pollinators with a short proboscis (nectar-gathering appendage) such as honeybees, ants, wasps, flies, and beetles can reach it when they crawl on the flower. On the other hand, bumblebees, butterflies, and moths have long proboscises, which enable them to reach nectar in less accessible places. For example, the long shape and curve of the columbine flower complements the long tongue of a bee, butterfly, or hummingbird. By concealing the nectar deep within its trumpet-like blossoms, the columbine prevents animals who are not its pollination partners from taking the nectar and transferring any pollen.

WHY ARE HUMANS ATTRACTED TO FLOWERS?

Are humans also pollinators?  Michael Pollan, author of “Botany of Desire” writes in his 2002 article called “Border Whores” that some evolutionary psychologists have proposed an interesting answer. Their hypothesis goes like this: our brains developed under the pressure of natural selection to make us good foragers, which is how humans have spent 99 per cent of their time on Earth. The presence of flowers is a reliable predictor of future food. People who were drawn to flowers, and who, further, could distinguish among them, would be much more successful foragers than people who were blind to their significance. In time the moment of recognition—much like the quickening one feels whenever an object of desire is spotted in the landscape—would become pleasurable, and the signifying thing a thing of beauty.

Humans have danced with the flowers, written poetry, songs and spent endless hours nurturing their flower gardens.  The flower is etched into our psyche- we are changed by the floral scents, the structure and the nectar.  Humans have used flowers for food and medicine for thousands if not millions of years.  It has only been recently that we have become “plant and flower blind. It has only been in the last 100 years that we have begun to call certain flowers “weeds” and have conducted a chemical warfare on our beloved inspirers.

We humans have lost the ability to love the plants and their flowers. We cannot see the connection between life on earth and the need to pave over paradise. We need to grow and protect fertility.  In ensemble that is what ecosystems do, it creates more and more opportunity for life. We need to create conditions conducive to life the same way flowers and plants do. Ban all the dangerous chemicals and stop making war on the natural world.  We need to make peace with the flowers and the plants and all species. Namaste.

CASCADIAN NATIVE PLANTS THAT YOU SHOULD KNOW ABOUT

Oceanspray-Pacific Ninebark-Spirea

Matthew Shepherd of the Xerces Society reports that there are approximately 900 species of bees and approximately 200 species of butterflies in the Cascadian bioregion.  Native plants are the forage of choice by these pollinators. Some native plants attract a great many pollinators.  Cascading plants such as Pacific Ninebark (Physocarpus capitatus), White Spirea (Spiraeabetulifolia), and Ocean Spray (Holodiscus discolor) could be attracting hundreds of types of pollinators.  They often grow near wetlands, stream banks and moist forest lands.  They should be included in all landscaping projects where ever possible. These essential native plants will bring wildlife into any garden or natural area and guarantee the pollination for many flowers.

Another extremely important indigenous plant is the Willow. The Willow species are the basis of a vital food web for insects, birds, small mammals, larger animals; many soil organisms, bacteria and fungi. They are a very important habitat.  In particular Apis mellifera, (the honey bee) an insect belonging to the Hymenoptera Order use the early blooming Willow flowers (catkins) to survive long wet, cold springs. These insects are not damaging to the willow leaves or flowers, but are feeding on nectar and are helping to pollinate other early blooming plants (Aliner 1992).

The flowers of the Willow are inflorescences, taking the form of catkins, which develop in a familiar way, through the loss of the bud scale and the revelation of the silky hairs of the ‘Pussy Willow’. Eventually, however, the anthers surmount the filaments of the stamens and reveal a vivid display of pollen from pale yellow through gold to shades of red and purple depending on the species.

BEE COLONY COLLAPSE – A CANARY IN THE MIND SHAFT?

And finally I leave you with this little video called “The Beauty of Pollination”.  The speaker is director and producer Louie Schwartzberg.  He is presenting his work as part of the TED TALKS.  His deep concern for the present bee colony collapse that is decimating pollinators worldwide caused him to take all his film making skills and present a dire message to the world.  “The destruction of the bee is like a canary in the coal mine- once the bees are gone, then the flowers will disappear. Once the flowers are gone – then we will be gone.” You cannot truly love the flowers if you do not love the pollinators. Feast your eyes on this TED TALK on

The Hidden Beauty of Pollination:

VOCABULARY

  • Anther: The anther is part of the stamen and produces the pollen.
  • Articulation: Another term for articulation is internode. Articulation describes the space between two nodes (joints).
  • Calyx: The whorl of sepals on the outside of a flower is referred to as the calyx.
  • Corolla: The whorl of petals is called the corolla.
  • Filament: The filament provides support for the anther in the stamen.
  • Floral Axis: The floral axis is the stem holding the reproductive flower parts.
  • Microsporangium: The microsprangium is located in the anther and produces microspores, which become male gametophytes. These male gametophytes will later be used in forming the pollen grains.
  • Nectary: The nectary produces nectar, a sweet liquid that attracts insects and birds for feeding. As they drink the nectar, the nearby pollen sticks to them and is transported to other flowers.
  • Ovary: The ovary houses the ovules and will become the fruit after pollination.
  • Ovule: The ovules contain egg cells and become the seeds after pollination.
  • Pedicel:The pedicel is the flower stalk.
  • Perianth: The perianth is the collective term for the calyx and corolla.
  • Petal: The petal is designed to attract pollinators to the flower and protect the stamen and pistil. Many have patterns that can be seen in ultraviolet light by bees and other insects. These indicate where the nectar is located.
  • Pistil: The pistil is the female reproductive part in the flower. It includes the ovary, style, and stigma.
  • Sepal: Sepals are found on the outside of the flower in a whorl. They are usually green. The group of sepals is called the calyx.
  • Stamen: The stamen is the male reproductive organ in the plant. It consists of the anther and filament.
  • Stigma: The stigma is the sticky surface where pollen lands and is collected to fertilize the ovules.
  • Style: The style is part of the pistil and holds the stigma above the ovary.

“The ‘Amen!’ of Nature is always a flower.”
– Oliver Wendell Holmes

I have been reading so much about flowers lately and I want to teach you what I learned as well as what I know.  So, I am going to teach about the flower in three parts.  Part 1: The history, physiology and pattern of the flowers (to help you identify flowering plants).  Part 2: Pollination and the sex life of flowers, and Part 3: The flower as a healing agent.

THE FLOWER – PART ONE

How did this happen. The flower is so different than any other tissue on the plant. The flower is a creation so beautiful and so attracting and it grows at the tip of the green or brown stem or branch of a plant. The flower is as intricately designed as if created to reflect the fractal formulas of the universe. The flower is designed to include color, shape, aroma, and chemical attractants to bring forth the pollinators so that it can complete its cycle of life: reproduction of itself.  How beautiful and how perfect it seems to us humans too. But, how is it created?  The answer is again found in the DNA of the plant and the meristem cells that drive the action in creating the plant. In this essay we are introduced to the Floral Meristem.

FLORAL MERISTEM

Last time we learned about the leaf.  We learned that the leaf was formed by the action of chemical changes and apical meristem cells.   The plant is reaching for the sun just as there is enough warmth, light, chemistry, moisture and food and creating new structures that will help it thrive.

The meristematic cells give rise to various organs of the plant, and keep the plant growing. The Shoot Apical Meristem (SAM) gives rise to organs like the leaves and flowers. When plants begin the developmental process known as flowering, the shoot apical meristem is transformed into an inflorescence meristem, which goes on to produce the floral meristem, which produces the familiar sepals, petals, stamens, and carpels of the flower. Floral meristem cells are responsible for determinate growth.  That is, they know exactly what they are supposed to create and that is the flower. And, this flower will live long enought to reproduce the plant and then die. The floral meristem cells direct the limited growth of the flower to a particular size and form. The transition from shoot meristem to floral meristem requires floral meristem identity genes that both specify the floral organs and cause the termination of the production of stem cells at just the right time. The floral meristem identity genes are “turned on” at the time the leaf meristem is turned on.  In fact some parts of flowers (bracts) are actually modified leafs. If you would like to learn more detail about this process please check out the wiki on Meristems located at http://en.wikipedia.org/wiki/Meristem

Queen Anne's Lace

THE HISTORY, PHYSIOLOGY AND PATTERN OF FLOWERS

The ancestors of flowering plants diverged from gymnosperms around 245–202 million years ago, and the first flowering plants known to exist are from 140 million years ago. They diversified enormously during the Lower Cretaceous and became widespread around 100 million years ago, but replaced conifers as the dominant trees only around 60–100 million years ago. (Wikipedia)

Non-flowering plants includes conifers, ginkgoes, ferns, cycads, horsetails, and mosses

A Flower is the reproductive structure of a tree or other plant, consisting of at least one pistil or stamen, and often including petals and sepals. According to botanist Brian Capon the flower is a short branch bearing specially adapted leaves, and reproduction is the sole function for which flowers evolved.

A land plant that flowers is called an angiosperm.  The Angiosperms are seed-producing plants like the gymnosperms and can be distinguished from the gymnosperms by a certain characteristics including  flowers, endosperm within the seeds, and the production of fruits that contain the seeds.

Flowers aid angiosperms by enabling a wider range of adaptability and broadening the ecological niches open to them. This has allowed flowering plants to largely dominate terrestrial ecosystems.

There are an estimated 352,282 unique flowering plant names, it is also estimated that there are approximately 69,500 known species of monocots and 49,500 known species of non-monocot species. The number of presently unknown plant species is thought to be 10 to 20 per cent or 20,000 to 30,000 species (Joppa, Roberts, and Pimm 2010).   The number of flowering monocot plants increased steadily for the last 250 years up until about 1850 when the number began to plateau.  There has been a steady decline in the last 50 years of known species and there are still species that have not been discovered.  The decline is due to habitat encroachment and environmental degradation.

MONOCOT VS DICOT – A REFRESHER

Monocot vs Dicot

Traditionally, the flowering plants have been divided into two major groups, or classes: the Dicots (Magnoliopsida) and the Monocots (Liliopsida).  The Dicotyledon is typically described as group of flowering plants whose seed typically has two embryonic leaves or cotyledons. The monocotyledon is typically described as having one embryonic leaf.

The Dicotyledon class has the following characteristics: – two seeds, – netted veins in the leaves, usually tap-rooted, usually complex branching, – flower parts mostly patterned in 4’s and 5’s. Example of the dicotyledon flowers would be: buttercup, rose, gentian and aster.

Monocotyledon class has the following characteristics: – one seed leaf, – parallel veins in the leaves, – horizontal rootstalks, – usually simple branching – flower parts mostly in 3’s. Examples of the flowers would be: arrowhead, lily and orchid.

FLOWER PHYSIOLOGY

Flower physiology

The parts of the flower are important to learn as the specific arrangement of flower parts will help you to identify a specific plant. There is a more complete list of flower parts with definitions at the end of this essay, but for now we will be focusing on petals, sepals, pistil, stamens, ovary, stigma, and style.

FLOWER PATTERNS OF SPECIFIC PLANT FAMILES

Mustard family – They have four free saccate sepals and four clawed free petals, staggered. The mustard family flower pattern includes 4 petals, 4 sepals, 4 tall stamens, 2 short stamens (Examples: Wild Mustard, Wall flower, Water Cress, Stock, Candytuft, and Lunaria)

The mints, taxonomically known as Lamiaceae or Labiatae – 5 united petals, (2 lobes up, 3 down), 5 untied sepals, 4 stamens (2 long, 2 short). Flower matures into a seed capsule containing four nutlets. (Examples: Horehound, Self Heal, Stinging Nettles, basil, mint, rosemary, sage, savory, marjoram, oregano, thyme, lavender, and perilla)

The Apiaceae (or Umbelliferae), commonly known as carrot or parsley family – 5 petals, 5 stamens, 2-cell ovary, compound umbels (Examples: angelica, anisewater hemlock, Water parsnip, Queen Anne’s lace, cow parsnip, parsnip, dill and fennel).

The Fabaceae or Leguminosae, commonly known as the legume, pea, or bean family – irregular flowers- 5 petals forming banner, wings and keel.  The keel consists of two petals fused together. Internal fused and free stamen. Fabaceae range in habit from giant trees (like Koompassia excelsa) to small annual herbs, with the majority being herbaceous perennials. (Examples: wisteria, pea, bean, acacia, mimosa, vetch,

Lilly or Lilium family is a genus of herbaceous flowering plants growing from bulbs, all with large, prominent flowers. – Flowers with parts in three. Sepals and petals usually identical. 3 sepals, and 3 petals (same size and color), 6 stamens, Pistil with a 3-parted stigma. (Examples: Tiger lilly, Shasta Lilly, Leopard Lilly,

Malvaceae, or the mallow family, is a family of flowering plants containing over 200 genera with close to 2,300 species.  5 petals, 5 sepals, bracts (modified leaves located at bottom of the flower), numerous stamens fused together as a column, pistil. The ovary is superior, with axial placentation. Capitate or lobed stigma. The flowers have nectaries made of many tightly packed glandular hairs, usually positioned on the sepals. The flowers are commonly borne in definite or indefinite axillary inflorescences, which are often reduced to a single flower, but may also be cauliflorous, oppositifolious or terminal. (Examples: hollyhock, okra, globe mallow, Hibiscus)

Sunflower or Aster family is an exceedingly large and widespread family of vascular plants.[3] The group has more than 22,750 currently accepted species, spread across 1620 genera and 12 subfamilies. Composites of many small flowers in disk-like flowerhead. Stigmas, 5 stamens fused around pistil, 5 petals fused together, pappus hair sepals, ovary. Even the petals are individual flowers. Each seed is produced by a single tiny flower. Multiple layers of bracts are common. (Examples: Dandelion, sunflower, asters, dahlia, Chrysanthemum, Gerbera, Calendula, Dendranthema, Argyranthemum, Dahlia, Tagetes, Zinnia).

Rose family Rosaceae (the rose family) are a medium-sized family of flowering plants, including about 2830 species in 95 genera. Roses can be herbs, shrubs or trees. Most species are deciduous, but some are evergreen.[2] They have a worldwide range, but are most diverse in the northern hemisphere. Arrangement of flowers is radially symmetrical and almost always hermaphroditic. Rosaceae generally have five sepals, five petals and many spirally arranged stamens. The bases of the sepals, petals, and stamens are fused together to form a characteristic cup-like structure called hypanthium. They can be arranged in racemes, spikes, or heads, solitary flowers are rare. (Examples of rose family includes many fruit varieties life apple, cherry, plum chokecherry as well as wild and domesticated roses)

There are several other families of flowers that I will explore in the future but for a full breakdown of all the flowering plant families check out Thomas Elpel’s book “Botany in a Day, The Pattern Method of Plant Identification”. He covers all the plant families including those I did not identify today such as : Heath family, Pyrola family, Indian Pipe family, Primrose family, Hydrangea family, Gooseberry family, Stonecrop family, Saxifrage family, Gentian, Dogbane, Milkweed, Nightshade, Morning Glory, Pholx, Waterleaf, Borage, Verbena, Plantain, Olive, Figwort, Broomrape, Bladderwort, Harebell, Madder, Honeysuckle, Teasel, Arrowhead, Arrow Grass, Water nymph, Pondweed, Spiderwort, Rush, Sedge, Grass, Cattail, Duckweed, Arum, Lily, Iris, and Orchid.

INFLORESCENCES – BRANCHING PATTERNS OF STEM OF THE FLOWER

An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Strictly, it is the part of the shoot of seed plants where flowers are formed and which is accordingly modified. The types of arrangements include: the spike, the raceme, the panicle, the umbel, the composite, the corium, capitulum and the thyrse. (Please see graphic of these patterns).

VOCABULARY

  • Anther: The anther is part of the stamen and produces the pollen.
  • Articulation: Another term for articulation is internode. Articulation describes the space between two nodes (joints).
  • Calyx:The whorl of sepals on the outside of a flower is referred to as the calyx.
    • Corolla: The whorl of petals is called the corolla.
    • Filament: The filament provides support for the anther in the stamen.
    • Floral Axis: The floral axis is the stem holding the reproductive flower parts.
    • Microsporangium: The microsprangium is located in the anther and produces microspores, which become male gametophytes. These male gametophytes will later be used in forming the pollen grains.
    • Nectary: The nectary produces nectar, a sweet liquid that attracts insects and birds for feeding. As they drink the nectar, the nearby pollen sticks to them and is transported to other flowers.
    • Ovary: The ovary houses the ovules and will become the fruit after pollination.
  • Ovule: The ovules contain egg cells and become the seeds after pollination.
  • Pedicel:The pedicel is the flower stalk.
  • Perianth: The perianth is the collective term for the calyx and corolla.
  • Petal: The petal is designed to attract pollinators to the flower and protect the stamen and pistil. Many have patterns that can be seen in ultraviolet light by bees and other insects. These indicate where the nectar is located.
  • Pistil: The pistil is the female reproductive part in the flower. It includes the ovary, style, and stigma.
  • Sepal: Sepals are found on the outside of the flower in a whorl. They are usually green. The group of sepals is called the calyx.
  • Stamen: The stamen is the male reproductive organ in the plant. It consists of the anther and filament.
  • Stigma: The stigma is the sticky surface where pollen lands and is collected to fertilize the ovules.
  • Style: The style is part of the pistil and holds the stigma above the ovary.

The Leaf

“Oh leaf, you must surely have found strength to force the branch to burst open so that you could emerge. What did you do to become free from the prison? Speak, Speak…” -Rumi

A leaf is like a flag unfurling.  The emerging leaf from the stem announces the beginning of the metamorphosis from stem to flower, from winter to spring.  It is the opening up of the new leaf that announces new life. Humans and animals begin to notice a plant once the leaf emerges.  It is our food and it is our hope for spring and the first harvest. Leaves provide brilliance in the spring and shade in the summer. They are perfect food containers and provide food for many species on the earth.  Later when the seasons turn to winter, the leaves that have fallen on the ground provide protection and fertilizer to the creatures of the forest and other environments.  Leaves provide more than half the human food needs.  Another large portion of leaves are used for the feeding of livestock.  Without leaves, humans would starve or die from malnutrition.

THE PRIMORDIAL LEAF

When last I wrote I told you about the mersistem cells and the apical cap or bud that is growing up toward the light. 

It is also, at precise intervals, creating appendages that will become branches and possibly leaves. The apical bud is involved in making the stem growing longer, initiates the orderly arrangements of leaves on the stem, and makes provision for the eventual development of branches.  This early period of leaf production in the mersistem bud is called leaf primordia. A primordium, the nascent leaf, forms at the least crowded part of the shoot meristem. The leaf cells fold over the meristem bud to protect it from sun and other weather. At just the right time, when the days are longer and the air temperature is warmer, the leaf begins to grow larger and then finally opens up.  At the base of the leaf primordia a bulge appears and it is called “axillary bud primordium” and is the beginning of a branch.   A branch forms at the axil or angle between the leaf and the stem.

Now the meristem cells are following the DNA blueprint of this plant whether it will be at maturity a tree or a sunflower.  And as the meristem cells formulate the stem it is remembering the specific design and pattern of this plant. It “remembers” at what interval to place the leaf nodes or the branch nodes.  The branch node of course can grow leaves as it extends its growth.

The cellular structure of the leaf is all about meristem cells, stomata, glucose storage and photosynthesis.   In review, the stomata’s main function is to allow gases such as carbon dioxide, water vapor and oxygen to move rapidly into and out of the leaf.  Stomata are found on all above-ground parts of the plant including the petals of flowers, petioles, soft herbaceous stems and leaves.

Leaf Stomata

Stomata are the main “food manufacturing” organs of the leaves. They make food from carbon dioxide and water in the presence of light during a process called photosynthesis. As stomata open in the presence of light, carbon dioxide will diffuse into the leaf as it is converted to sugars through photosynthesis inside the leaf. At the same time, water vapor will exit the leaf along a diffusive gradient through the stomata to the surrounding atmosphere through the process of transpiration.

Another very interesting thing happens at the point that the meristem cells decide to create a leaf.  The cells start to create new chemicals.  One such chemical is chlorophyll.  And, cell tissue that is filled will chlorophyll will turn green. Leaves receive their green color during the process of trying to absorb energy from the sun. The sunlight strikes the leaves, which contain chlorophyll, and the chlorophyll reacts by emitting the green color. Likewise in the autumn some plant leaves turn color because as the days shorten and leaves absorb less light, the leaves prepare for autumn by stopping the food-making process. Consequently, the production of chlorophyll drops off, turning some leaves orange and yellow in the fall.

Colors, like yellow and orange, are in leaves all summer, but the powerful green chlorophyll overwhelms them. Once the cold shorten days come on in the fall, chlorophyll disappears and the leaf’s other colors shine through.

THE PATTERN IS THE KEY

Each plant has a pattern for growing stems, branches and leaves.

  • A leaf is connected to the stem by a structure called the petiole.

▫         The base of the stem where the petiole connects is called the node

▫         Where the petiole connects to the leaf is called the axil

▫         The axil is where we happen to find buds, clusters, and emerging leaves.

Leaves appear on the stem in a set pattern.  Learning the leaf patterns will help you identify the plant and help you use plant keys

Leaf Morphology: Shape and arrangement, margin and venation

Studying the different shapes and designs of the leaf will also help you to identify a plant.  Each plant has a pattern of growth.  Identifying the overall shape of the leaf, the outer edge of the leaf (margin) and the pattern of leaf veins will help you to identify or key the plant type. Developing a keen eye for observation will help.  I actually draw the leaf so I can more fully study it.

Overall Shape of the leaf

Many plants have adapted leaf shapes that help water drip off the plant to avoid too much moisture, which might make bacteria and fungus grow.  The leaf shape and arrangement on the stem will funnel water to the root. The leaf shape may provide a platform to collect the sun’s rays or keep wind from blowing the plant apart.

Arrangement of the leaf on the stem

Leaf arrangement types on the stem

In botany the word “phyllotaxis” is a word used to describe the study of the arrangement of the leaf on a plant stem. .  There are four primary leaf arrangements:  Alternate, opposite, whorled and rosulate. (Please see illustration).

  • Opposite      leaves are positioned across the stem      from each other, with two leaves at each node.
  • Alternate (spiral) leaves are arranged in alternate steps along      the stem, with only one leaf at each node.
    Whorled leaves are arranged in circles along the stem.
    Rosulate leaves are arranged in a rosette around a stem with      extremely short nodes.

Leaf Margins

Leaf Morphology Chart

The leaf margin is the outer edge of a leaf. There are many different margins.  Here is a list of margin types listed on Wikipedia .  Learning these types of margins will help you to key a plant.  (Please see illustration on left. CLICK TO ENLARGE -also found on Wikipedia -thank you Wikipedia!).

  • ciliate: fringed with hairs
  • crenate: wavy-toothed; dentate with rounded teeth, such as Fagus (beech)
  • crenulate finely or shallowly crenate
  • dentate: toothed, such as Castanea(chestnut)
    • coarse-toothed: with large teeth
    • glandular  toothed:  with teeth that bear glands.
  • denticulate: finely toothed
  • doubly toothed: each tooth  bearing smaller teeth, such as Ulmus (elm)
  • entire: even; with a smooth margin; without toothing
  • lobate: indented, with the indentations not reaching to the center, such as many Quercus(oaks)
  • palmately lobed:  indented with the indentations reaching to the center, such as Humulus (hop).
  • serrate: saw-toothed  with asymmetrical teeth pointing forward, such as Urtica (nettle)
  • serrulate: finely serrate
  • sinuate: with deep, wave-like indentations; coarsely crenate, such as many Rumex (docks)
  • spiny or pungent: with stiff, sharp points, such as some Ilex (hollies) and Cirsium (thistles).

Design of the veins found on the leaf

There are two subtypes of venation, namely, craspedodromous, where the major veins stretch up to the margin of the leaf, and camptodromous, when major veins extend close to the margin, but bend before they intersect with the margin.

  • Feather-veined, reticulate arise from a single mid-vein and subdivide into veinlets. These, in turn, form a complicated network. This type of venation is typical for (but by no means limited to) dicotyledons.
  • Palmate-netted or fan-veined; several main veins diverge from near the leaf base where the petiole attaches, and radiate toward the edge of the leaf, e.g. most Acer (maples).
  • Parallel-veined      or parallel-ribbed– veins run parallel for the length of the leaf, from the      base to the apex. Commissural veins (small veins) connect the major      parallel veins. Typical for most monocotyledons, such as grasses.
  • Dichotomous – There are no      dominant bundles, with the veins forking regularly by pairs; found in Ginkgo and some pteridophytes.

LEAVES FOR FOOD AND MEDICINE

For as long as humans have been on the earth, the leaves of plants have been used for food, medicine, shelter and utility.  Green has been a sacred color to those cultures who understood the important relationship between humans and plants. Leaves were used in ceremony, clothing and decoration.

Children learned rhymes and axioms that taught them to identify the helpful and not so helpful plants around them. Here are just a few:

  • The leaves of three, Leave it be. The leaves of four have some more. (a song to teach a child to identify Poison oak or Ivy)
  • Hairy vine? No friend of mine!
  • Berries white, danger in sight!
  • Red leaflets in spring are a dangerous thing.
  • Side leaflets like mittens will itch like the dickens!
  • Berries of red will soon be dead!
  • Berries of black, caution for that. Or ”Berries of black, ask about that.”

Nutrition of plant leaves

Humans have been able to survive the long months to the first harvest by storing food and by harvesting early spring plants.  Roots are important through the winter months. But the early green leaves of Stinging Nettles (Urtica dioica), Miners lettuce (Claytonia perfoliata), Dock (Rumex patientia L,) Dandelion (Taraxacum) and hundreds of other species have allowed humans to survive until the next great harvest.

Nutritional – Medicinal

There were a number of plants that were known by the First Peoples of Cascadia that helped humans survive starvation and nutritional imbalance. Known by Europeans as “Spring tonic” plants, these plants with their new shoots are full of nutrients that are helpful to our well being. For instance- Stinging Nettle (Urtica dioica) when picked young, can be steamed and eaten in February and March. This plant has been known to alleviate muscle pain, depression and tiredness. It truly is a spring tonic. Stinging Nettle is often found in semi-wet well drained areas.

Stinging Nettle (Urtica dioica) and the Spring Potherb

Stinging Nettle (Urtica diocia)

Stinging Nettle is a herbaceous perennial flowering plant, native to Europe, Asia, northern Africa, and North America,and is the best-known member of the nettle genus Urtica.  It was a survival plant for First Peoples and others who moved here to live. It is a key ingredient in the Spring Potherb. This is a soup where early plants are steamed and cooked into a broth and drunk to get one’s body ready for spring and summer. It wakes up the body, mind and spirit. The greens are also consumed.  The greens contain vitamin C, iron and many minerals.

Recipe for the Spring Potherb

Bring a big pot of water to boil, turn down the heat.  Place plants into the water and turn off heat.  Season to taste.

Stinging Nettle
Chickweed
Clover
Dandelion leaf and root
Great Burdock
Lamb’s Quarters

The fresh leaves of Stinging Nettle contain vitamins A, C, D, E, F, K, P, and b-complexesas well as thiamin, riboflavin, niacin, and vitamin B-6, all of which were found in high levels, and act as antioxidants. The leaves are also noted for their particularly high content of the metals selenium, zinc, iron, and magnesium. They contain boron, sodium, iodine, chromium, copper, and sulfur.

Stinging Nettle is a versatile plant. The plant is not only eaten, but as the plant matures the fibers of the plant were used for making many useful things. The fibers have been used for thousands of years for shoes, hats, fabric for clothes, fishing line, and was woven into twine and rope. The use of Nettle fiber worldwide is the similar to the use of Hemp or Flax. Used to weave fabric of all kinds, it is has also been used to press into paper. The nettle fiber is usually mixed with other paper-making plants as it does not possess the gluey substance needed to allow the paper fabric to hold together.

The Sting of the nettle is said to be a cure for Arthritis and other diseases of muscles, joints, and some organ tissues.

The antidote for being stung by this plant is the juice found inside the stem or Dock (Rumex patientia) which usually grows nearby. A Plantain (plantago macrocarpa) or (plantago lanceolata) poultice can also be used as antidote for the sting.
NEVER COLLECT THESE PLANTS ALONG POLLUTED WATERWAYS, ROADS OR INDUSTRIAL AREAS. This plant, as well as all plants, is adapted to uptake dangerous heavy metals (bio-remedial). Always harvest in safe areas.

“Nature will bear the closest inspection. She invites us to lay our eye level with her smallest leaf, and take an insect view of its plain.” – Henry David Thoreau

Vocabulary

Axillary bud primordium – An immature axillary bud. An embryonic side shoot. A point on a stem, at the node, and between the stem and leaf, where a new shoot can develop. Growth is usually inhibited at these buds.

Leaf primordia – A lateral outgrowth from the apical meristem that develops into a leaf

Petiole – The stalk that joins a leaf to a stem; leafstalk

Photosynthesis – The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Transpiration – the emission of water vapor from the leaves of plants. Water loss that occurs through the open plant stomata (tiny pores primarily on the underside of the leaf). Rate of loss is determined by wind and atmospheric humidity conditions.
