Madia elegans is an annual herbaceous plant species in the family Asteraceae. It is generally known as the common madia, but there are several subspecies known by various common names. [1]
The Madia elegans plant is native to western North America from south-central Washington (state) to northern Baja California. [2] [1] [3] [4] It may be found in dry open forest, disturbed areas and grasslands from low to high elevations. [2]
Madia elegans is covered with short, stiff hairs. Glands are borne on stalks, especially near the flowers. [1] The showy flower varies in appearance across subspecies and even within subspecies. Typically, it is a bright yellow daisy-like bloom with numerous thin ray flowers and several central disk flowers. It may be solid lemon yellow or have a center of a different color, from white to maroon. Several strongly scented, uncrowded, flower heads grow at the end of a slender green stem. The ray flowers curl up during the daytime, opening in the late afternoon and staying open all night until mid-morning. It flowers from April through early November. [2] Its fruits are achenes which were historically used as food by Native Americans, including the Pomo and Miwok, who baked them or ground them into flour.
The foliage exudes a fragrant oil, hence the common name of tarweed.
Madia is a genus of annual or perennial usually aromatic herbs with yellow flowers, in the tribe Madieae within the family Asteraceae.
Hemizonia is a genus of plants in the family Asteraceae. They are known generally as tarweeds, although some tarweeds belong to other genera, such as Madia and Deinandra. Furthermore, Hemizonia is currently being revised; some species may be segregated into new genera.
Platanthera elegans is a species of orchid known by several common names, including elegant piperia, coast piperia, hillside rein orchid, and hillside bogorchid. This is a showy flowering plant native to western North America. It grows from a caudex tuber and sends up a thick stem just under a meter in maximum height. The stem is topped with a cylindrical spike inflorescence of densely packed flowers with curving white to greenish-yellow petals. Coastal individuals are noticeably thicker and have more flowers than those that grow further inland; it is uncertain if these are variants, subspecies, or even separate species. They are both currently treated as P. elegans. Other species of Plantanthera, notably the endangered species P. yadonii are quite similar in appearance to some populations of this species.
Hemizonia congesta, known by the common name hayfield tarweed, is a species of flowering plant in the family Asteraceae, native to western North America.
Kyhosia is a monotypic genus of flowering plants in the family Asteraceae containing the single species Kyhosia bolanderi, which is known by the common names Bolander's madia and kyhosia.
Harmonia doris-nilesiae is a species of flowering plant in the family Asteraceae known by the common names serpentine tarweed and Niles' madia.
Madia exigua is a species of flowering plant in the family Asteraceae known by the common names small tarweed and threadstem madia.
Madia glomerata is a species of flowering plant in the family Asteraceae known by the common name mountain tarweed.
Madia gracilis is a species of flowering plant in the family Asteraceae known by the common names grassy tarweed, slender tarweed, and gumweed madia.
Anisocarpus madioides is a North American species of flowering plant in the family Asteraceae known by the common name woodland madia.
Madia radiata is a species of flowering plant in the family Asteraceae known by the common names golden madia and showy madia. It is endemic to California, where it is known mostly from the Central Coast Ranges and adjacent edges of the San Francisco Bay Area and Central Valley.
Madia sativa, known by the common names coast tarweed and Chilean tarweed, is a species of flowering plant in the family Asteraceae found in parts of western North and South America.
Harmonia stebbinsii is a species of flowering plant in the family Asteraceae known by the common name Stebbins' tarweed, or Stebbins' madia. It is endemic to northern California, where it is limited to the Klamath Mountains and adjacent slopes of the North Coast Ranges. It is a member of the serpentine soils plant community in these mountains, found at elevations of 1100–1600 meters. It is a rare annual herb producing a bristly stem up to about 25 centimeters tall studded with black resin glands. Its bristly leaves grow up to about 2 centimeters long and are mostly gathered near the base of the plant. The inflorescence is an array of flower heads lined with hairy, glandular, purple-tipped phyllaries. The head has a few yellow ray florets several millimeters long and yellow disc florets. The fruit is an achene tipped with a pappus.
Deinandra increscens is a species of flowering plant in the family Asteraceae known by the common name grassland tarweed. It is endemic to California, where it has been found primarily in Monterey, San Luis Obispo and Santa Barbara Counties. A few isolated populations have been reported from Kern and Merced Counties, but these are from urban areas and probably represent cultivated specimens.
Deinandra fasciculata, known by the common names clustered tarweed and fascicled spikeweed, is a species of flowering plant in the family Asteraceae native to western North America.
Calochortus umpquaensis is a species of flowering plant in the lily family known by the common name Umpqua mariposa lily. It is endemic to Oregon in the United States, where it is mainly limited to the region of the Klamath Mountains on the Little River in Douglas County, in particular the Watson and Ace Williams Mountains. The flower has also been found at a single location in each of Josephine and Jackson Counties.
Calochortus coxii is a rare species of flowering plant in the lily family known by the common names Cox's mariposa lily and crinite mariposa lily. It is endemic to Oregon in the United States, where it is known only from Douglas County.
Deinandra minthornii — — is a rare California species of flowering plant in the family Asteraceae known by the common name Santa Susana tarplant, or Santa Susana tarweed. It is listed as a rare species by the California Department of Fish and Wildlife and on the California Native Plant Society Inventory of Rare and Endangered Plants of California.
Centromadia pungens, the common spikeweed or common tarweed, is a species of North American plants in the tribe Madieae within the family Asteraceae. It is native to northern Baja California and the western United States. The plant is considered a noxious weed in parts of the Pacific Northwest.
Deinandra lobbii, the threeray tarweed, is a North American species of plants in the tribe Madieae within the family Asteraceae.
