Bromus erectus is a perennial, tufted grass with basal tufts of
cespitose leaves that is
nonrhizomatous. The culms grow between in height. The
internodes are typically glabrous. The flattened
cauline leaves have pubescent or glabrous sheaths. The leaf blades are long and wide. The grass lacks
auricles and the
ligule is blunt but finely serrated, sometimes with hairy edges. The contracted and ellipsoid
panicle is usually upright, rather than nodding, measuring long. The lanceolate
spikelets are long and have five to twelve flowers. The
glumes are acute, with the lower glumes one-nerved and long, and the upper glumes three-nerved and long. The glabrous or slightly scabrous
lemmas are prominently nerved and long, with
awns long. The
anthers are long.
