NEED IN SITU PHOTOS. Purple three-awn is a common grass of lower elevations in the Watershed. Many varieties of Aristida purpurea have been named. It ranges from alkali flats to the foothills. The three awns on each lemma and unequal glumes should distinguish it (the other Aristida in the Watershed, A. arizonica, has unequal glumes). In the USA, the species is also common in all states from the eastern Great Plains to the eastern slopes of the Sierras. In the Rio Grande drainage, it is a familiar grass all the way to the Gulf of Mexico.
