Primrose Monkey Flower

Emigrant Wilderness, Huckleberry Lake, July 2014
Ivesia lycopodioides is a species of flowering plant in the rose family known by the common name clubmoss mousetail, or clubmoss ivesia. It is native to the Sierra Nevada and to regions east of the range in California. It may also be found beyond the state line into Nevada. This is a perennial herb which grows in the crevices of rock ledges in the mountains and in wet high-elevation meadows. It produces a rosette of flat to cylindrical leaves up to 15 centimeters long, each of which is made up of many tiny, lobed leaflets. The stems may grow erect or drooping to 30 centimeters long and each holds an inflorescence of clustered flowers. Each flower has hairy, greenish triangular sepals and much larger oval-shaped petals of bright yellow. In the center of the flower are usually five stamens and several pistils.

rangerbuttons-emw14v

Ranger Buttons

Emigrant Wilderness, Huckleberry Lake, July 2014
Sphenosciadium is a monotypic genus of flowering plants in the carrot family containing the single species Sphenosciadium capitellatum, which is known by the common names ranger's buttons, woollyhead parsnip, button parsley, and swamp whiteheads.

The plant is native to western North America from Idaho through Nevada, Oregon, and California into Baja California. It grows in moist habitat types, such as creeksides and meadows. It is included in Toxic Plants of North America (Burrows & Tyrl, 2001).

Ranger's buttons plants are quite similar to the other large Umbelliferae that share similar habitats: Sierra angelica and cow parsnip, but each has a very differently shaped leaf, and the other two have umbellets with quite distinct flowers, in contrast to the tight balls on ranger's buttons.

It is a stout perennial herb growing from a tuberous root and producing an erect stem often exceeding 1 meter (3.3 ft) tall and sometimes approaching 1.2 meters (3.9 ft). The stem and leaves are usually green but sometimes nearly white in color, smooth below but with rough hairs on the inflorescence. The leaves are divided into several segments which bear widely spaced leaflets. The leaflets may also be intricately divided into small segments.

The inflorescence is a whitish compound umbel with many branches each up to 10 centimeters long. The nearly spherical, headlike terminal umbellets contain many tiny white or purple-tinged flowers, whose protruding stamens make them appear very fuzzy in full bloom.

Rapeseed

Dorney, U.K., May 2010
Rapeseed (Brassica napus), also known as rape, oilseed rape, rapa, rappi, rapaseed (and in the case of one particular group of cultivars, canola) is a bright yellow flowering member of the family Brassicaceae (mustard or cabbage family). The name derives from the Latin for turnip, napus, and is first recorded in English at the end of the 14th century. Older writers usually distinguished the turnip and rape by the adjectives round and long(-rooted) respectively.[2] See also Brassica napobrassica, which may be considered a variety of Brassica napus. Some botanists include the closely related Brassica campestris within B. napus. (See Triangle of U).

Rapeseed oil is used in the manufacture of biodiesel for powering motor vehicles. Biodiesel may be used in pure form in newer engines without engine damage, and is frequently combined with fossil-fuel diesel in ratios varying from 2% to 20% biodiesel. Formerly, owing to the costs of growing, crushing, and refining rapeseed biodiesel, rapeseed derived biodiesel cost more to produce than standard diesel fuel. Rapeseed oil is the preferred oil stock for biodiesel production in most of Europe, partly because rapeseed produces more oil per unit of land area compared to other oil sources, such as soy beans.

There is however concern over the use of rapeseed for use as biodiesel because rapeseed is currently grown with a high level of nitrogen-containing fertilisers, and the manufacture of these generates N2O, a potent greenhouse gas with 296 times the global warming potential of CO2. It has been estimated that 3-5% of nitrogen provided as fertilizer for rapeseed is converted to N2O.[9]

Red Elderberry

Emigrant Wilderness, Huckleberry Lake, July 2014
Sambucus racemosa is a species of elderberry known by the common name Red Elderberry.

This often treelike shrub grows 2 to 6 meters tall. The stems are soft with a pithy center. Each individual leaf is composed of 5 to 7 leaflike leaflets, each of which is up to 16 centimeters long, lance-shaped to narrowly oval, and irregularly serrated along the edges. The leaflets have a strong disagreeable odor when crushed. The inflorescence is a vaguely cone-shaped panicle of several cymes of flowers blooming from the ends of stem branches. The flower buds are pink when closed, and the open flowers are white, cream, or yellowish. Each flower has small, recurved petals and a star-shaped axis of five white stamens tipped in yellow anthers. The flowers are fragrant and visited by hummingbirds and butterflies. The fruit is a bright red or sometimes purple drupe containing 3 to 5 seeds.

Sierra Fireweed

Emigrant Wilderness, Huckleberry Lake, July 2014
Chamerion angustifolium, commonly known as fireweed (mainly in North America), great willow-herb (some parts of Canada), or rosebay willowherb (mainly in Britain), is a perennial herbaceous plant in the willowherb family Onagraceae. It is native throughout the temperate Northern Hemisphere, including large parts of the boreal forests.

The reddish stems of this herbaceous perennial are usually simple, erect, smooth, 0.5–2.5 m (1½–8 feet) high with scattered alternate leaves. The leaves are entire, lanceolate, and pinnately veined. A related species, dwarf fireweed (Chamerion latifolium), grows to 0.3–0.6 m tall.

This herb is often abundant in wet calcareous to slightly acidic soils in open fields, pastures, and particularly burned-over lands; the name Fireweed derives from the species' abundance as a coloniser on burnt sites after forest fires. Its tendency to quickly colonize open areas with little competition, such as sites of forest fires and forest clearings, makes it a clear example of a pioneer species. Plants grow and flower as long as there is open space and plenty of light. As trees and brush grow larger the plants die out, but the seeds remain viable in the soil seed bank for many years; when a new fire or other disturbance occurs that opens up the ground to light again, the seeds germinate. Some areas with heavy seed counts in the soil can, after burning, be covered with pure dense stands of this species and when in flower the landscape is turned into fields of color.

Flowering Jul–mid Sep. Loose sandy or gravelly, mainly volcanic soils or scree (rarely on serpentine), openings in or above subalpine conifer forests; 1900–3200 m; Calif., Nev.

Chaenactis nevadensis is known mainly from the northern Sierra Nevada and southern Cascade Range (Shasta to Placer counties, California; Washoe County, Nevada). It was recently discovered disjunct on ultramafic rocks of Bully Choop Mountain west of Redding, California, where it approaches small forms of C. suffrutescens in habit (see discussion there). It is sometimes cultivated in rock-gardens and may be found beyond its native range. Chaenactis nevadensis and C. suffrutescens appear to be sister or ancestor-derivative species. I have seen no evidence to support reports that C. nevadensis intergrades with C. alpigena (P. Stockwell 1940, as C. nevadensis var. mainsiana), with C. douglasii var. alpina (M. Graf 1999), or with any other taxon.

Sunflower

Black Mesa, Oklahoma, September 2008
Common sunflower is a widely branching, stout annual, 1 1/2-8 ft. tall, with coarsely hairy leaves and stems. The terminal flowers heads are large and showy, up to 5 in. across. A tall, coarse leafy plant with a hairy stem commonly branched in the upper half and bearing several or many flower heads, the central maroon disk surrounded by many bright yellow rays. Yellow ray flowers surround brown disk flowers.

The state flower of Kansas. The heads follow the sun each day, facing eastward in the morning, westward at sunset; the name in Spanish means looks at the sun. The plant has been cultivated in Central North America since pre-Columbian times; yellow dye obtained from the flowers, and a black or dull blue dye from the seeds, were once important in Native American basketry and weaving. Native Americans also ground the seeds for flour and used its oil for cooking and dressing hair. In the 19th century it was believed that plants growing near a home would protect from malaria. In the United States and Eurasia seeds from cultivated strains are now used for cooking oil and livestock feed. Many variants have been developed, some with one huge head topping a stalk 9-16 (3-5 m) tall, others with maroon rays. Prairie Sunflower (H. petiolaris), found throughout the Great Plains and similar to the wild forms of Common Sunflower, has scales on the disk in the center of the head tipped by white hairs, easily visible when the central flowers are spread apart. Developed in a single large head variety by Russians.

Sticky Cinquefoil

Mt Hoffman, Yosemite, August 2010
A leafy plant with several stems, often reddish and sticky with minute, glandular hairs, topped by yellow flowers in loose branched clusters. A variable, semi-woody species with many subspecies. The leaves are reminiscent of strawberry, but have more leaflets. They are pinnately compound. The rather small flowers vary from cream to yellow and occur in small, loose clusters. The upper stems have glandular hairs, hence the name. Overall height is from 1-2 ft.

This attractive wildflower is common in the West and generally recognizable as a cinquefoil, a name ultimately deriving from Latin through French, meaning five leaves; some species have leaves with five leaflets. The genus differs from very similar-appearing species of buttercups (Ranunculus) in having a hypanthium. Some species hybridize; others reproduce asexually. Hybrids may reproduce asexually, and populations of intermediate plants are frequent. Identification of cinquefoil species is therefore difficult.

Swamp Onion

Mt Dana, Yosemite, August 2010
Allium validum, known by several common names including swamp onion, wild onion, Pacific onion, and Pacific mountain onion, has been previously classified as a member of the lily family, Liliaceae; however, it is now thought to be in the Alliaceae. Allium validum is native to California.

The Allium validum bulb is three to five centimeters long, ovoid and clustered on the short end. The outer coat of the stout rhizome is brown or gray in color, fibrous, and vertically lined. The stem is 50 to 100 centimeters long and angled. There are three to six leaves more or less equal to the stem and the leaves are flat or more or less keeled. There are 15 to 40 flowers with pedicels being seven to twelve millimeters in length. The flower itself is six to ten millimeters, its perianth parts are more or less erect, narrowly lanceolate, acuminate, and entire with a rose to white color. The stamens are exerted and there is no ovary crest.

The bulb A. validum can be used as a flavoring for soups and stews although it is somewhat fibrous. The leaves can be eaten raw or cooked and the flowers can be used as garnish on salads. There are no noted medicinal uses, but it is believed to have the same beneficial effects on health as other members of the genus. The sulphur compounds help reduce blood cholesterol levels, act as a tonic to the digestive system and help get the circulatory system moving.

Western Bistort

Hetch Hetchy, Yosemite, May 2008
Polygonum bistortoides (American bistort, western bistort, smokeweed or mountain meadow knotweed), syn. Bistorta bistortoides, is a perennial herb in the genus Polygonum.

It is distributed throughout the Mountain West in North America from Alaska and British Columbia south into California and east into the Rocky Mountains. The plant grows from montane foothills to above the timberline, although plants growing above 7,500 feet are smaller and seldom reach more than 12 inches in height. Plants in other areas may reach over half a meter-1.5 feet tall. The leaves are leathery and up to 40 centimeters long, and are mostly basal on the stem. The dense cylindrical to oblong inflorescence is packed with small white to pinkish flowers, each a few millimeters wide and with protruding stamens.

American bistort was an important food plant used by American Indians living in the Mountain West, and the roots are edible either raw or fire-roasted with a flavor resembling chestnuts. The seeds can be dried and ground into flour and used to make bread. They were also roasted and eaten as a cracked grain.

  • Polygonum bistortoides Pursh
  • American bistort, Western Bistort
  • Polygonaceae (Buckwheat Family)
  • USDA Symbol: POBI6
  • USDA Native Status: Native to U.S.

White Mountain Heather

Ansel Adams Wilderness, Garnet Lake, August 2011
A low, matted, evergreen shrub with tough branches up to 12 in. tall. Small white bell-like flowers hang from the tips of slender stalks that grow from the axils near the ends of the branches on this matted plant. One to few bell-shaped flowers are borne near the branch tips. Because the flowers are pendent, the reddish sepals are visible.

The somewhat star-like white flowers may have inspired the genus name of this plant, for in Greek mythology Cassiopeia was set among the stars as a constellation. Firemoss Cassiope (C. tetragona), near the Canadian border, has a prominent groove on the lower side of each leaf. Starry Cassiope (C. stellariana), which grows in bogs from Mount Rainier northward, has alternate, spreading leaves.

  • Cassiope mertensiana (Bong.) G. Don
  • Western moss heather, Western moss-heather
  • Ericaceae (Heath Family)

Willow Stem Gall Sawfly

Emigrant Wilderness, Huckleberry Lake, July 2014
Galls or cecidia are outgrowths on the surface of lifeforms. Plant galls are abnormal outgrowths of plant tissues and can be caused by various parasites, from fungi and bacteria, to insects and mites. Plant galls are often highly organized structures and because of this the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite plant galls. In pathology, a gall is a raised sore on the skin, usually caused by chafing or rubbing.

Gall-inducing insects include gall wasps, gall midges, gall flies, Agromyzidae aphids (such as Melaphis chinensis, Pemphigus spyrothecae, and Pemphigus betae), scale insects, and psyllids.

Willow Shoot Galls: These swellings on shoots, twigs, or leaf petioles, may be caused by small flies (midges) or small wasps (sawflies).The gall increases in size as long as the immature stages are active. They cause no significant injury.The infestation may be reduced by pruning and destroying the galled areas before the adult insect emerges, usually in late summer.

Wolf Lichen

Kennedy Meadows, Stanislaus National Forest, April 2015
Letharia vulpina ("wolf lichen") on incense cedar bark, western slope of the Sierra Nevada, California. Letharia columbiana, in the previous portrait, is its sister species.

This was the most widely used dye lichen for indigenous peoples in western North America, used from the Rockies to the Pacific coast, from California to Alaska. Some groups also made paint from it.

This lichen is sufficiently poisonous that the Achomawi in Northern California used it to make poison arrowheads, but the Okanagan-Colville made a weak tea of it to treat internal problems, and it was a Blackfoot remedy for stomach disorders.

The thallus, or vegetative body, has a fructicose shape — that is, shrubby and densely branched — and a bright yellow to yellow-green, or chartreuse color, although the color will fade in drier specimens. Its dimensions are typically 2 to 7 cm (0.79 to 2.76 in) in diameter. The vegetative reproductive structures soredia and isidia are present on the surface of the thalli, often abundantly.

Yarrow

Emigrant Wilderness, Huckleberry Lake, July 2014
Yarrow grows to 3 feet tall and has no branches except near the top. The leaves are alternate, 3-5 inches long, with many leaflets on each side of the midrib (1- pinnately lobed); and these are further divided into smaller leaflets, giving them a delicate, fernlike, lacy appearance. Flower heads are arranged in large, compact clusters at the top of the stem, each cluster consisting of 1 or more flower heads. The flower head has 20-25 yellowish-white (rarely pink) ray flowers and similarly colored disk flowers.

Achillea millefolium is highly variable and has been treated both as a single species with varieties and as multiple distinct species. A. millefolium is cosmopolitan throughout the Northern Hemisphere. In North America, A. millefolium is a complex of both native and introduced plants and their hybrids.

  • Achillea millefolium L.
  • Common yarrow, Yarrow, Milfoil, Western yarrow
  • Asteraceae (Aster Family)

Yellowstone Fireweed

Yellowstone National Park, Gardner Hole, September 2012
Chamerion angustifolium, commonly known as fireweed (mainly in North America), great willow-herb (some parts of Canada),[1] or rosebay willowherb (mainly in Britain), is a perennial herbaceous plant in the willowherb family Onagraceae. It is native throughout the temperate Northern Hemisphere, including large parts of the boreal forests.

The reddish stems of this herbaceous perennial are usually simple, erect, smooth, 0.5–2.5 m (1½–8 feet) high with scattered alternate leaves. The leaves are entire, lanceolate, and pinnately veined. A related species, dwarf fireweed (Chamerion latifolium), grows to 0.3–0.6 m tall.

This herb is often abundant in wet calcareous to slightly acidic soils in open fields, pastures, and particularly burned-over lands; the name Fireweed derives from the species' abundance as a coloniser on burnt sites after forest fires. Its tendency to quickly colonize open areas with little competition, such as sites of forest fires and forest clearings, makes it a clear example of a pioneer species. Plants grow and flower as long as there is open space and plenty of light. As trees and brush grow larger the plants die out, but the seeds remain viable in the soil seed bank for many years; when a new fire or other disturbance occurs that opens up the ground to light again, the seeds germinate. Some areas with heavy seed counts in the soil can, after burning, be covered with pure dense stands of this species and when in flower the landscape is turned into fields of color.
