NEED IN SITU PHOTOS. Roughleaf ricegrass has been vouchered somewhat often, but almost always from the South San Juan Moutains. The two other locations are near Creston and La Veta pass in the North Cristos. The typical habitat of Oryzopsis asperifolia is understory of mixed conifer woods in the montane. Identification is made easy by the plant's prostrate nature, with very reduced blades and broad basal leaves twisted upside-down. The USA distribution is rather dislocated: central and southern Rockies; Idaho and Wyoming near the Canadian border; upper mid-West, Great Lakes, and New England along the Canadian border. The species follows the Rio Grande drainage through the top third of New Mexico but no farther.
