Abstract

Astragalus pilosior Spellenb. & E.W. Anderson is described and illustrated as a new species. It is known to occur in the pine forests of southwestern Chihuahua, Mexico, on the western slopes of the Sierra Madre Occidental between approximately 1900 m and 2500 m elevation. The new species is placed in the section Strigulosi. It is compared with the recently described A. spellenbergii from southwestern Durango, Mexico.
