Eriogonum mitophyllum is known only from the Arapien Shale badlands above Lost Creek northeast of Sigurd, Sevier County. It is allied to E. ostlundii, but differs in its linear leaf blades, narrow, strict inflorescences with di- and trichotomous, U-shaped branches, and longer, pale yellow flowers. The leaf blades are threadlike and the narrowest of any species in the genus. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
