Taxonomic Comments
This record is for a broad treatment of Encelia virginensis , including E. virginensis var. actonii, as recognized in Kartesz (1994). Clark in FNA (2006, vol. 21) and Kartesz (1999) recognize it more narrowly, excluding the variety as a distinct species, E. actonii.

Rank Reasons
Encelia virginensis is in southeastern California (500-1500 meters) and southern Nevada to southwestern Utah (760-1325 meters), Arizona, and perhaps southwestern New Mexico; it occurs on gravelly substrates, including desert flats and rocky slopes, as well as roadsides. Hybrids of E. farinosa x E. frutescens resemble this species (Clark in Hickman 1993).
