The branches of var. sesquimetralis radiate, forming large, round plants that hug the ground. This habit, coupled with a long season of available water, is evidently conducive to long-continuing flowering and fruiting but is not necessarily an indication of a near relationship to other taxa that are similar (see discussion under 285c. var. multiracemosus). The variety is restricted to southern Mineral County, Nevada, and northern Inyo County, California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Variety micans is a local adjunct of the variable var. variabilis (D. Isely 1998), restricted to the southern end of Eureka Valley in Inyo County, California, and adjacent to Big Dune and in the Amargosa Desert, near Lathrop Wells in Nye County, Nevada. Isely questioned its recognition at varietal rank, initially considering it a local dune-specialized ecotype. Although it is ordinarily a strong perennial, some plants are evidently short-lived, a feature shared with var. coulteri. Variety micans is in the Center for Plant Conservation’s National Collection of Endangered Plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
