Bromus latiglumis (Shear) Hitchc.
Coefficient of Conservatism: 6
Coefficient of Wetness: -3
Wetness Index: FACW
Physiognomy: Nt P-Grass

River banks, floodplain forests, thickets, and forested ravines.

Bromus latiglumis, B. nottowayanus, and B. pubescens form a complex of three native forest understory species that are often confused. In addition to the distinctions in the key, B. latiglumis is a larger, leafier species and ripens its fruit late, generally toward the latter part of August and into September, whereas B. nottowayanus and B. pubescens fruit at least a month earlier. Rarely specimens of this group have the first glume 3-nerved and the second glume either 3- or 5-nerved. They will not run well to any species in the other half of the key, but will rather obviously belong here on the basis of all other characteristics.
