BROMUS TECTORUM
24. Bromus tectorum L. DOWNY BROME-GRASS, DOWNY CHESS.
A slender tufted annual, rarely occurring in pastures which have been seeded at some time.
Leaves rolled in the bud-shoot. Sheath not compressed, keeled, softly pubescent, pale green, often pink or purple tinged, split part way only. Auricles absent. Collar pubescent, pale, narrow, distinct, usually divided. Ligule membranous, 1.5 to 2.5 mm. long, truncate, lacerate or coarsely ciliate near apex. Blade 4 to 8 mm. wide, 5 to 12 cm. long, flat, softly pubescent, sharp pointed, pale green; margins pilose.
This species is distinguished from B. ciliatus by its longer ligule and from B. inermis by its pubescence.
