Agnorhiza
''Agnorhiza'' is a small genus of flowering plants in the family Asteraceae described as a genus in 1998. Its species had previously been considered members of either ''Wyethia'' or ''Balsamorhiza''. The plants are native to California, with the range of one species ''(A. ovata)'' extending into northern Mexico. They are perennial herbs with sunflower-like flower heads A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, compos ... 1 to 4 centimeters wide. ; Species * '' Agnorhiza bolanderi'' - Bolander's mule's ears * '' Agnorhiza elata'' - Hall's mule's ears * '' Agnorhiza invenusta'' - Coville's mule's ears * '' Agnorhiza ovata'' - southern mule's ears * '' Agnorhiza reticulata'' - El Dorado mule's ears References External links USDA Plants Profile for ''Agnorhiza'' Heliantheae Flora ...

Agnorhiza Reticulata
''Agnorhiza reticulata'' (syn. ''Wyethia reticulata''), known by the common name El Dorado County mule's ears, is a rare species of flowering plant found only in a small region of north-central California. ''Agnorhiza reticulata'' grows in the California interior chaparral and woodlands habitats of the Sierra Nevada foothills. It has been found in El Dorado, Sacramento, and Yuba Counties. The genetic diversity of the populations is probably low because they are often clonal, spreading via vegetative reproduction with rhizomes rather than sexual reproduction by seed. Some populations are also threatened by development of their habitat.Ayres, D. R. and F. J. Ryan.

Wyethia
''Wyethia'' is a genus of North American flowering plants in the family Asteraceae. First published by Thomas Nuttall in J. Acad. Nat. Sci. Philadelphia vol.7 on page 39 in 1834. These plants are commonly referred to as mule's ears. They are short, low to the ground golden-rayed wildflowers that resemble miniature sunflowers. The genus is named for an early explorer of the western United States, American Nathaniel Jarvis Wyeth, 1802–1856.

Heliantheae
The Heliantheae (sometimes called the sunflower tribe) are the third-largest tribe in the sunflower family (Asteraceae). With some 190 genera and nearly 2500 recognized species, only the tribes Senecioneae and Astereae are larger. The name is derived from the genus ''Helianthus'', which is Greek for sun flower. Most genera and species are found in North America (particularly in Mexico) and South America. A few genera are pantropical. Most Heliantheae are herbs or shrubs, but some grow to the size of small trees. Leaves are usually hairy and arranged in opposite pairs. The anthers are usually blackened. The above statements about the size and distribution of the tribe apply to a broad definition of Heliantheae, which was followed throughout the 20th century. Some recent authors break the tribe up into a dozen or so smaller tribes. Uses Commercially important plants in the Heliantheae include sunflower and Jerusalem artichoke. Many garden flowers are also in this group, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Willis Linn Jepson
Willis Linn Jepson (August 19, 1867 – November 7, 1946) was an early California botanist, conservationist, and writer. Career Born at Little Oak Ranch near Vacaville, California, Jepson became interested in botany as a boy and explored the adjacent San Francisco Bay Area. He came in contact with various botanists before he entered college. In 1892, at the age of 25, Jepson, John Muir, and Warren Olney formed the Sierra Club, in Olney's San Francisco law office. From 1895 to 1898, Jepson served as instructor in Botany and carried on research at the University of California, Berkeley, Cornell University (1895), and Harvard University (1896–1897). He received his Ph.D. at Berkeley in 1899. He was made assistant professor in 1899, associate professor in 1911, professor in 1918, and professor emeritus in 1937. He was a Professor of Botany at UC Berkeley for four decades, thus his entire career was identified with the University of California. Jepson founded the Californi ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Balsamorhiza
''Balsamorhiza'' is a genus of plants in the family Asteraceae known commonly as balsamroots. These are perennials with fleshy taproots and caudices bearing erect stems and large, basal leaves. Atop the tall stems are showy yellow sunflower-like blooms. Balsamroots are native to western North America (United States and Canada). Native Americans used the sticky sap of this plant as a topical antiseptic for minor wounds. The entire plant is edible and nutritious, but not necessarily enjoyable because it contains a bitter, strongly pine-scented sap. The large taproots produced by ''Balsamorhiza sagittata'' are edible and were harvested, dried, and ground into a starchy flour by Native Americans when other food plants were scarce. The plants' large taproots are reported to be very palatable and far less bitter than the above-ground parts of the plant.Edible and Medicinal Plants of the West, Gregory L. Tilford, The plant grows on dry hillsides and dry open meadows throughout the M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
