Involucres 9–13 mm. Phyllaries narrowly ovate. Ray florets 11–21; corolla laminae 8–15 mm. Disc corollas yellow, 5–6 mm. Cypselae 5–8 mm; pappi usually 0, rarely of 1–2 bristlelike awns. 2n = 36.

Discussion
In the mountains of the eastern Mojave Desert in California, Encelia virginensis may intergrade with E. actoni at higher elevations, probably as a result of hybridization. Plants of E. virginensis in New Mexico may be adventive.
