232 86. GRAMINA. 



Bromus arvensis, Linn. 



Area [1 2 (8) 4 5 * 7 8 9 (10) 11 12 13 14 (15) 16]. 



Alien. Has occasionallj^ but very seldom, been found 

 in Britain ; and then only as an introduced and temporary 

 straggler. I have seen specimens from the provinces of 

 Thames (Mr. G. S. Gibson), and Fife (Mr. Syme). All 

 the other specimens seen by myself under name of B. 

 arvensis in English collections, and these have been 

 rather numerous, belonged to B. commutatus. 



Bromus, Sp. var. 



B. PATULUS, M. (f -ST. — (Area 10). Alien. In Yorksliire, 

 accidentally introduced (Bab. Man). 



B. SQUAREOSUS, Linn. — [Area 12 3]. Alien or incognit. 

 Said to have been found in Somerset, Sussex, and the 

 Metropolitan circuit. But either some errors have oc- 

 curred about the species, or the specimens observed had 

 probably arisen from imported seeds. 



B. RiGiDus, Roth. — Area (15). Alien. Said to have 

 been found in Fifeshire, and perhaps the same thing with 

 the B. madritensis indicated from the same county. 



B. TECTORUM, Linn. — Area (3 * 15). Alien. Some- 

 what hastily taken hold of, and described as a true 

 English species lately, on the faith of specimens found 

 near a flax-mill at Hoddesdon, in Hei-tfordshire. G. 

 Don enumerates the plant, or at least the name, in his 

 Account of the Botany of Forfarshire.
