156 TRIANDR1A— DIGYNIA. Bromus. 



length of the glume, strongly divaricated when dry ; 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 syuarrosus, 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 that 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.
