Shady woodlands often near streams. Associated with Arnica cordifolia, Artemisia ludociciana, and Antennaria microphylla. There is a clear intergradation between A. microphylla and A. umbrinella. The plants in collection number 1431 were taken from an area of about 3 meters radius, yet the bracts vary in color from dark green-umber to rosy pink. The usefulness of distinguishing species within such a population is doubtful. A. microphylla is also related to A. parviflora, which is the only other species in the area that can have rosy bracts. But the specimens I collected appear well marked and show no confusing intermediate characters. Voucher: Whitehead, G.S. 1983. M.S., Idaho State U. Flora of the Island Park Geothermal Study Area.
