Bromus frondosus (Shear) Woot. & Standl.
A weeping brome with short awns and 3-nerved, glabrous glumes. This species can be difficult to distinguish from Bromus anomalus and Bromus porteri, but is the only one of the three that can have glabrous lemmas (plants vary, however, and the lemmas are sometimes pubescent!).
