Diagnostic Characteristics
This subspecies, which is considered non-native, is contrasted from subsp. pumpellianus (which is recognized as a species in Flora North America) by its (usually) glabrous lemmas (which can be sparsely short-hairy at the base and along the margins), usually glabrous nodes and leaf blades, and the absence of awns or awns no more than 3 mm long (Pavlick and Anderton, 2007, Fl. North America, Vol. 24).

Range Comments
Widespread and non-native, across most of North America excluding southeastern states where it is absent (FL) or rare (others) (Kartesz 2009).
