Drier clear cuts and sagebrush communities, to the summit of Mt. Two Top. Usually on bare soil. Associated with Agoseris aurantiaca, Arnica parrvi, Hieracium albiflorum, and Epilobium spp.; or with Artemisia tridentata, and Eriogonum umbellatum. This species is easily confused with Microseris nigrescens, but can be distinguished on the basis of its conspicuously hairy herbage and involuvcre as compared to nearly glabrous herbage of Microseris. Also the Microseris specimens I collected have shorter scapes and an inflated involucre. Voucher: Whitehead, G.S. 1983. M.S., Idaho State U. Flora of the Island Park Geothermal Study Area. Duplicates to: IDS, RM. Phenology: Flowers.
