Of conservation concern. Although Erigeron multiceps has been considered to be indistinct or doubtfully distinct from E. divergens (see G. L. Nesom 1993f), California botanists with field experience note that the two taxa can be distinguished when occuring in close proximity. Plants of the type collection and some others have thick taproots and thickened caudex branches, unlike closely related species. Plants from Clark County, Nevada (Red Rock Canyon Recreation Area, Leary 4031, UNLV) have taproots with simple caudices, decumbent-ascending, strigose stems, and persistent basal leaves; they are technically, at least, identified as E. multiceps. The disjunct Mexican plants are closely similar to those in California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
