[1] }} Bromus erectus, commonly known as erect brome,[2] upright brome or meadow brome,[1] is a dense, course, tufted perennial grass. It can grow to {{convert|120|cm}}. Like many brome grasses the plant is hairy.[3] The specific epithet erectus is Latin, meaning "erect". The diploid number of the grass is 56. DescriptionBromus erectus is a perennial, tufted grass with basal tufts of cespitose leaves that is nonrhizomatous. The culms grow between {{convert|0.6-1.2|m|abbr=on}} in height. The internodes are typically glabrous. The flattened cauline leaves have pubescent or glabrous sheaths. The leaf blades are {{convert|10-20|cm|abbr=on}} long and {{convert|2-6|mm|abbr=on}} 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 {{convert|7-15|cm|abbr=on}} long. The lanceolate spikelets are {{convert|1.5-3|cm|abbr=on}} long and have five to twelve flowers. The glumes are acute, with the lower glumes one-nerved and {{convert|7-9|mm|abbr=on}} long, and the upper glumes three-nerved and {{convert|9-11|mm|abbr=on}} long. The glabrous or slightly scabrous lemmas are prominently nerved and {{convert|10-15|mm|abbr=on}} long, with awns {{convert|5-6|mm|abbr=on}} long. The anthers are {{convert|4-6|mm|abbr=on}} long. B. erectus flowers in June and July.[4][5]RangeFound 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.[3] References1. ^1 Bromus erectus was first described and published in Flora Anglica 39. 1762. {{cite web|url=http://tropicos.org/Name/25509394 |title=Name - Bromus erectus Huds.|work=Tropicos|publisher=Missouri Botanical Garden|location=Saint Louis, Missouri|quote=Locality: Habitat in cretaceis circa Rochester, Dartford et Gravesend, in Cantino; Distribution: England|accessdate=May 22, 2011}} 2. ^{{PLANTS|id=BRER3|taxon=Bromus erectus|accessdate=20 June 2016}} 3. ^1 {{cite book |title=Grasses |author=C.
