Eriogonum ordii is infrequently encountered (rarely locally common) along the inner Coast Ranges from Monterey and San Benito counties south through Fresno, Merced, and San Luis Obispo counties to Ventura County, then eastward across northern Los Angeles County to the hills east of Bakersfield in Kern County. This distribution is based on confirmed modern collections. The type (J. G. Lemmon 4189, ASU, BM, DS, G, GH, ISC, K, P, UC, US) supposedly was collected near Fort Mohave, Mohave County, Arizona, in 1884. Two T. Brandegee specimens reportedly were gathered on the boundary of San Diego and Imperial counties, one at Split Mountain (Apr 1905, UC) and the second along San Felipe Creek (4 Apr 1901, UC). Brandegee’s label data often are dubious, and these disjunct sites are discounted. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
