NEED IN SITU PHOTOS. Colorado wildrye has been vouchered four times from the Watershed: somewhere in Alamosa Co, "ruderal, in sandy soil" (1931); in the vicinity of Del Norte, associated with Juncus ater (Rio Grande Co, 1935); along a dike by the practice field on the Adams State University campus (Alamosa Co, 1976); and five miles northeast of Hooper (Saguache Co, 1986). Howeve, Ackerfied (2015, 2022) marks only Alamosa Co. BONAP marks Saguache and Alamosa counties, and adds Costilla. A new review of all the vouchers seems in order. Usually Leymus ambiguus grows in dry foothills among rocks. In the USA, the main distribution for the species is southern Wyoming, Colorado (western slope and Front Range), and south central New Mexico. It does not follow the Rio Grande drainage any farther down stream.
