Eriogonum gracillimum is found in the Coast, Transverse, and scattered mountain desert ranges in Fresno, Inyo, Kern, Kings, Los Angeles, Madera, Merced, Monterey, Riverside, San Benito, San Bernardino, San Diego, San Luis Obispo, Santa Barbara, and Tulare counties. The species is often common and occasionally even weedy. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Eriogonum anemophilum, in a strict sense, is known only from the limestone ridges and slopes of Star Peak in the West Humboldt Range of Pershing County. Also included within the present circumscription are plants from tuffaceous hills in Reese River Valley in Lander County, and from scattered sites on low hills in northeastern Eureka and southwestern Elko counties. A third set of populations occurs elsewhere in Pershing County (Jersey Valley and the Tobin and Trinity ranges) and just over the line in Humboldt County. Each group differs slightly from the others, the plants of the mountain ranges tending to be more robust, with obovate to suborbiculate leaf blades, compared to the plants of lower elevations, which have narrower leaf blades. Plants from Eureka and Elko counties have a grayish leaf tomentum, while those from the valleys of Humboldt, Pershing, and Lander counties have a greenish or tawny leaf tomentum. What, if any, taxonomic recognition these groups merit has not been determined. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
