Annual. July. 



Root small, fibrous. Stem a foot high, simple, smooth, striated, 

 leafy except at the upper part. Leaves linear, narrow, many- 

 ribbed, besprinkled with soft hairs. Sheaths clothed with hairs 

 pointing downwards, like the two last species. Siipula short, 

 blunt, hairy. Spikelets few, pendulous, large and tumid, full an 

 inch long.' Calyx strongly ribbed. Florets from 8 to 12 or 15^ 

 closely imbricated. Outer valve of the corolla elliptical, con- 

 cave, somewhat inflexed at the edges, with 3 or 4 crowded very 

 evident ribs at each side, the whole surface either minutely 

 downy, more or less, or densely hairy, as described by Buxbaum 

 and Host ; the summit deeply cloven, furnished at the cleft 

 with a strong, dorsal, rough, tapering, twisting au-n, about the 

 length of the glume, strongly divaricated when diy ; inner valve 

 obtuse, entire, not one third so broad as the outer, strongly 

 fringed with distant bristles, and attached to the upper concave 

 side of the seed. Nectary permanent at the base of the seed, on 

 the opposite convex side. 



Having never been able to see, in any collection, a native British 

 specimen of this species, and having received B. secalinus from 

 Sussex as squarrosus, by means of an old friend of Mr. Hud- 

 son's, I have always doubted the accuracy of his report. If 

 Mr. G. Don had ever seen the true plant, his correct eye could 

 not have confounded it with any other ; and yet tliat it should 

 be found '' in various parts of Scotland," though generally con- 

 fined to the south of Europe, seems, as Professor Hooker hints, 

 not probable.
