Eriogonum clavatum is the tall, slender member of the E. inflatum complex found on the Inner Coast, Peninsular, and Transverse ranges of southern California. It is rather common from Monterey and San Benito counties southward to Ventura, northwestern Los Angeles, and extreme southwestern Kern counties, and then disjunct in the Peninsular Ranges of Riverside and San Diego counties, where it just enters north-central Baja California, Mexico. It extends eastward onto desert ranges, where it rarely exceeds 6 dm in height, from southern Mono County and Inyo County south through western San Bernardino County to northwestern Riverside County. From Inyo County, the species occurs across southern Nye and northern Clark counties into western Lincoln County, Nevada.

Varieties 3 (3 in the flora). Eriogonum deflexum is common and often weedy throughout most of its range. It is an important source of small seed for birds. The reported use of the stem (M. L. Zigmond 1981, as E. insigne) by the Kawaiisu people as a smoking pipe is incorrect; the taxon in point was actually E. deflexum var. baratum. The desert metalmark butterfly (Apodemia mormo deserti) is found in association with E. deflexum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
