160 TRIANDRIA— DIGYNIA. Bromus. 



rather slender, round, smooth, sometimes taking root from the 

 lower joints. Leaves linear, narrow, flaccid, soft and downy on 

 both sides, with a few longer hairs at the edges towards the 

 bottom. Sheaths striated, angular, clothed more or less with 

 deflexed hairs. Stipula short, obtuse, finally torn. Panicle a span 

 long, spreading, like the last, but smaller and less subdivided. 

 Spikelets pendulous, lanceolate, rough to the touch, tinged with 

 purplish brown, an inch long. Florets finally more remote, as 

 well as more numerously and strongly ribbed, than the pre- 

 ceding, with intermediate furrows ; the inner valve notched, its 

 ribs more strongly fringed. Awn purplish, half as long again as 

 its glume. Nectary deeply divided. Stamens always 3, as in all 

 the foregoing. Germen obovate. Styles lateral, very short. Stigmas 

 small, feathery, cylindrical. Seed lanceolate, channelled along 

 the upper side, and united to the inner valve of the corolla. 

 The specific name alludes to the unprofitable nature of this grass 

 for the farmer. To whatever genus B. asper belongs, the present 

 species ought not to be separated from it, any more than the 

 following.
