- NEED IN SITU PHOTOS. Purple reedgrass has been fairly often collected from the montane, subalpine, and tundra in all mountain regions of the Watershed. Calamagrostis purpurascens prefers dry rocky slopes, unlike the other wide-spread species in the Watershed, C. canadensis. Again the awn is a crucial determinant trait, rising from the base of the lemma and twisted within the lemma and geniculate beyond it. The species is found in all Western USA states with the exception of Arizona. It follows the Rio Grande drainage just barely into New Mexico, no farther down stream
