Perennials, 3.5–8 cm; taprooted, caudices simple or branched, relatively long, woody. |

Erigeron oreophilus is similar to E. neomexicanus in its perennial habit, typically pinnatifid leaves, white, reflexing rays, and 10–12 readily falling pappus bristles; it has a vestiture of dense, viscid, stipitate glands and sparse, spreading, nonglandular hairs.

Erigeron lackschewitzii is closely similar to E. ochroleucus and perhaps derived from it. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
