Bastardsage

Eriogonum wrightii Torr. ex Benth.

Comments

provided by eFloras
Eriogonum wrightii is subdivided into several varieties most of which are distinct, although a few have rather indistinct boundaries. Some of the variation has yet to be fully resolved, especially in the var. nodosum complex where, at least in Mexico, one additional expression remains to be named. A clear distinction between var. subscaposum and E. kennedyi is not possible in southern California (see discussion below). Nearly all of the varieties of E. wrightii are in cultivation, although the most elegant (var. olanchense) has yet to be so honored.

Few ethnobotanical uses of bastard-sage are reported in the literature. L. C. Wyman and S. K. Harris (1951) noted that the Kayenta Navajo use it (var. wrightii) as an emetic, while M. L. Zigmond (1981) stated that the Kawaiisu used the pounded seeds (probably of var. subscaposum) in a beverage or as a dry meal. Members of the species are food plants for the rare Rita dotted-blue butterfly (Euphilotes rita), the Pacific dotted-blue (E. enoptes), the veined blue (Plebeius neurona), and the Mormon metalmark (Apodemia mormo mormo).

Eriogonum wrightii

provided by wikipedia EN

Eriogonum wrightii is a species of wild buckwheat known by the common names bastardsage and Wright's buckwheat. It is native to the Southwestern United States, California, and northwest Mexico, where it grows in many plant communities, such as chaparral, in rocky habitats from mountains to deserts.

Description

It is quite variable in appearance; it may be a small perennial herb 10 centimeters tall or a bushy shrub over a meter wide. There are several varieties as well. In general it has basal leaves as well as a few leaves along the stem, which are usually narrow and woolly. The inflorescence has long, straight branches which may be hairless to woolly and have flower clusters and sometimes small leaves at the nodes. The flowers are usually white to light pink.

Taxonomy

Varieties[1][2][3]

  • Eriogonum wrightii var. brevifolium Reveal (San Borja buckwheat) – An uncommon endemic from the Sierra de San Borja in Baja California to the Tres Vírgenes in Baja California Sur.
  • Eriogonum wrightii var. dentatum (S. Stokes) Reveal (La Mision buckwheat) – A rare endemic occurring along the mesas and bluffs above the Pacific coast between La Mision and Ensenada, Baja California.
  • Eriogonum wrightii var. linearifolium Reveal (Linear-leaf island buckwheat) – A rare endemic existing on Angel de la Guarda Island in the Gulf of California.
  • Eriogonum wrightii var. membranaceum S. Stokes ex Jeps. (Foothill buckwheat, Ring-stem buckwheat) – In Mexico, this variety occurs in the upper foothills and mountains of the Sierra de Juarez and the Sierra de San Pedro Martir and disjunctly to the south in the Sierra La Asamblea. In the United States, it is found in California, occurring primarily in the Peninsular Ranges.
  • Eriogonum wrightii var. nodosum (Small) Reveal (Knot-stem buckwheat, bastardsage) – A rare variety occurring in the more arid portions of the southwest. In Mexico, it occurs in Sonora, and the Baja California Peninsula, on the Sierra de Juarez and Sierra de San Pedro Martir south to the Sierra de San Borja in Baja California and on the Cerro Azufre in Baja California Sur. In the United States, it is found in Arizona and California.
  • Eriogonum wrightii var. olanchense (J.T. Howell) Reveal
  • Eriogonum wrightii var. oresbium Reveal (San Pedro Martir buckwheat) – An uncommon variety endemic to the Sierra de Juarez and the Sierra de San Pedro Martir in Baja California, Mexico. Differs from all other forms of the species with its broadly elliptic to nearly oval leaf blades.
  • Eriogonum wrightii var. subscaposum S. Watson
  • Eriogonum wrightii var. taxifolium (Greene) Parish (Yew-leaf buckwheat) – A rare variety endemic to Cedros Island, but also on the Punta Baja near El Rosario in Baja California.
  • Eriogonum wrightii var. trachygonum (Torr. ex Benth.) Jeps.
