Varieties 3 (3 in the flora). Intermediates between var. austiniae and var. chrysopsidis are formed in Oregon and Idaho, where their ranges overlap. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Erigeron lemmonii is found only in the Scheelite Canyon, Huachuca Mountains (Cochise County), on Fort Huachuca Military Reservation. The basal portion of the stems may be “subnaked and rhizomatous in appearance, but apparently not subterranean” (A. Cronquist 1947). (Discussion copyrighted by Flora of North America; reprinted with permission.) |

1. Ray laminae well developed (surpassing involucres); involucres 3.5–7.5 mm; stems hirsuto-villous or strigose | → 2 |
