Eriogonum davidsonii

Eriogonum davidsonii is a species of wild buckwheat known by the common name Davidson's buckwheat. This plant is native to the southwestern United States and northern Baja California, where it grows in sandy or gravelly soils in a variety of habitats. It is a spindly annual herb growing up to 40 centimeters in height. The fuzzy leaves are located at the base of the plant and are one or two centimeters wide and round with wavy or wrinkly margins. It is variable in appearance, but is generally erect with thin, naked, neatly branching stems bearing clusters of tiny flowers at widely spaced nodes. Each flower is about 2 millimeters wide, bell-shaped, and usually pink.

Notes

Comments

Eriogonum davidsonii is widespread and mostly common to occasionally abundant or weedy in Arizona, California, southern Nevada, and southern Utah. It is exceedingly variable. In the northern part of California, its range approaches that of E. luteolum var. luteolum, and the two can be difficult to differentiate. To the south, in Tulare County, the distinction between E. davidsonii and E. luteolum var. pedunculatum also is difficult. Specimens of Eriogonum davidsonii with curved inflorescence branches resemble E. cithariforme in the mountains of southern California, and care must be taken to separate E. davidsonii from its more robust relative, E. molestum in the San Jacinto Mountains of Riverside County. The disjunct populations in Utah and Arizona are somewhat different in appearance but presently do not seem worthy of taxonomic separation. The epithet juncinellum is available should recognition be desired.  

Seeds of Davidson's wild buckwheat were pounded into a meal and eaten dry by the Kawaiisu people of southern California (M. L. Zigmond 1981).
