Description
Bromus erectus is a perennial, tufted grass with basal tufts of cespitose leaves that is nonrhizomatous. The culms grow between 0.6-1.2 m in height. The internodes are typically glabrous. The flattened cauline leaves have pubescent or glabrous sheaths. The leaf blades are 10-20 cm long and 2-6 mm 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 7-15 cm long. The lanceolate spikelets are 1.5-3 cm long and have five to twelve flowers. The glumes are acute, with the lower glumes one-nerved and 7-9 mm long, and the upper glumes three-nerved and 9-11 mm long. The glabrous or slightly scabrous lemmas are prominently nerved and 10-15 mm long, with awns 5-6 mm long. The anthers are 4-6 mm long. B. erectus flowers in June and July.

Range
Found on well-drained calcerous soils in disturbed areas, fields, and roadsides, B. erectus is widespread in Europe, South West Asia, North West Africa, and has been introduced into North America.
