Perennial. July. August. 



Root tufted, of many strong, partly woolly, fibres. Stems three or 

 four feet high, erect, simple, leafy, round, striated, smooth, with 

 several joints. Leaves nearly upright, a foot long, lanceolate, 

 taper-pointed, dark green, broad, flat, with a mid-rib which is 

 pale underneath, and several parallel, lateral, roughish ribs ; the 

 interstices striated ; edges rough. Sheaths striated, smooth and 

 naked, not hairy ; the upper ones longer than their leaves j 

 lower short. Stipula very short, brown or purplish, often jagged, 

 with an acute auricle at each side, clasping the stem. Panicle a 

 little drooping, twice compound, the primary branches 2 or 3 

 together, the rest alternate, all angular and rough. Spikelets 

 alternate, drooping, ovate, not half an inch long without the 

 awns, generally of 4 or 5 perfect/forete, with the rudiments of 

 another. Valves of the calyx lanceolate, keeled, pointed j the 

 outer narrow, sometimes awl-shaped, without any lateral ribs ; 

 inner with 3 rough ribs, including the keel. Outer valve of the 

 corolla ovate-lanceolate, scarcely keeled, 5 -ribbed at the upper 

 part, smooth, acute, and often cloven, at the summit, the mid- 

 rib extended into a capillary, rough, whitish, often wavy, awn, 

 half as long again as the glume ; inner valve very thin, a little 

 concave, cloven at the point, its lateral ribs smooth to the naked 

 eye, but appearing under a magnifier finely downy, as in others 

 of this genus, not coarsely fringed as in Bromus. Nectary 

 acutely cloven. Germen elliptic-oblong. Styles short. Stigmas 

 feathery, oblong, scarcely compound. Seed oblong, dark brown,
