Abstract

Astragalus amnis-amissi (Fabaceae), also known as Lost River milkvetch, is a plant endemic to East-central Idaho for which no published surveys have been completed in the last 17 years. A search of several previouslydocumented populations in canyons of the Southern Lemhi Range and the Lost River Range, in Butte and Custer Counties, Idaho, documented the species in four canyons. However, it was not relocated in an unnamed canyon in the Southern Lemhi Range, indicating potential extirpation of that population. No new populations of A. amnis-amissi were found.
