TRIANDRIA— DIGYNIA. Bromus. J51 



Gramen spica brizse majus. Bauh. Prodr. 18./. Theatr. 133./. 

 Rail Syn. 392. Moris, v. 3. 205. 



G. loliaceum corniculatum. Sckeuchz. Agr. 35. 



In open fields and heaths on a chalky soil. 



Not uncommon in Yorkshire, Oxfordshire, and Kent. 



Perennial. July. 



Root scalv, slightly creeping. Whole plant more rigid, and less 

 hairy than the last, the spike more elegant, erect, and smooth, 

 with more numerous florets, whose awns are shorter than the 

 glumes, and sometimes scarcely evident. The inflexed edges of 

 the inner valve of the corolla almost meet, covering the seed, 

 though quite unconnected therewith ; their ribs are less strongly 

 fringed than in F. sylvatica. 



52. BROMUS. Brome-grass. 



Linn. Gen. 36. Juss. 32. Fl. Br. 125. Lam. t. 46. 



Cat. of 2 unequal, ovate or lanceolate, acute, compressed, 

 awnless, many-ribbed valves, containing an ovate, or ob- 

 long, compressed, imbricated spikelet, of many alternate, 

 two- ranked, awned, perfect Jlorets. Cor. of 2 unequal 

 valves; the outer elliptical, rarely lanceolate, concave, 

 scarcely compressed, more or less ribbed, longer than the 

 calyx, flat, or a little inflexed, at the edges ; cloven at the 

 summit; awned at the back just below the summit; awn 

 tapering, wavy, direct, generally as long as the glume, 

 or longer, decurrent at the base ; inner glume nearly as 

 long as the outer, but much narrower, two-ribbed, cloven 

 or entire at the summit, its margins membranous, folded 

 in at each rib, which is strongly fringed with rather di- 

 stant bristles, curved upward. Nect. a deeply divided 

 scale, or of 2 distinct entire ones. Filam. capillary, shorter 

 than the cor., sometimes but 2. Anth. generally short, 

 pendulous, notched at each end. Germ, ovate. Styles 

 distant, lateral. Stigmas densely feathery. Seed elliptic- 

 oblong, depressed, downy at the summit, concave or 

 channelled on the upper side, which is united to the un- 

 changed inner valve of the corolla, the other valve being 

 usually loose. 



Root mostly annual or biennial ; perhaps always one or the 

 other in the genuine species. Stems one or more, erect, 

 simple, leafy. Herbage more or less downy, or hairy. 

 Panicle somewhat branched, many-flowered.

 Panicle spreading; slightly subdivided below. Spikelets
