Varieties 3 (3 in the flora). Eriogonum jamesii is a nectar source for the rare Spalding dotted-blue butterfly (Euphilotes spaldingi). Eriogonum jamesii and E. arcuatum (see below) are considered “life medicines” and used ceremonially by Native Americans (C. Arnold, pers. comm.; A. B. Reagan 1929; P. A. Vestal 1952). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum mancum is widely scattered in Butte, Clark, Custer, and Lemhi counties of southeastern Idaho, in Beaverhead, Broadwater, Carbon, Deer Lodge, Gallatin, Granite, Jefferson, Lewis and Clark, Madison, Powell, Ravalli, and Silver Bow counties in western Montana, and in Big Horn County of northwestern Wyoming. It is disjunct on limestone outcrops in the House Range of Millard County, Utah, no doubt a Pleistocene relic. Plants from the rim of Little Mountain west of Kane, Big Horn County, Wyoming (B. E. Nelson 5407, BRY, MARY, NY, RM, UTC), and those just to the north in southern Carbon County, Montana (Lesica 2632, 5379, 5405, 5439, and 5453, MONTU), have tepals with a few long, pilose hairs along the midrib adaxially. These populations are well isolated from others of the species, but the taxonomic significance of this expression has yet to be determined.
