Comments

Eriogonum hoffmannii is known only from the Death Valley region (M. DeDecker 1974) of Inyo County. Nearly all of its known populations are within the boundaries of Death Valley National Park (a few plants occur just to the west along California Highway 190 southeast of Travertine Point). It is of special concern but is well managed and protected.

Eriogonum hoffmannii

provided by wikipedia EN

Eriogonum hoffmannii is a species of wild buckwheat known by the common name Hoffmann's buckwheat. It is endemic to Inyo County, California, where it is found only in the mountains around Death Valley; most of the known populations of the plant are located in Death Valley National Park.[1] The plant grows in the desert scrub on the slopes of the Panamint, Black, and Funeral Mountains.

Description

This buckwheat is an annual herb growing up to a meter in height with a slender flowering stem. The round woolly leaves are located about the base of the stem. The inflorescence is a series of branches lined with smaller branches bearing many small clusters of tiny white, pink, or reddish flowers.

There are two varieties of this species. The more common, var. robustius, takes an erect form up to a meter tall, while var. hoffmannii is a shorter, spreading plant.
