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 piscinensis is known from Fish Slough northwest of Bishop in Mono County. It is similar in habit to vars. multiracemosus and sesquimetralis. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
