Nothing can be more diftincl; than this common Bromus from the 

 two already mentioned.. Its compound denfe panicle, and its 

 ftrongly-ribbed, deprefTed, clofely imbricated glumes, at once dif- 

 tinguifh it. Few plants vary more as to luxuriance. The B. nanus, 

 of Weigel, fent by himfelf to. Linnaeus, is a ftarved dwarf variety r 

 with few fpikes in the panicle, as it often grows on walls. The 

 fame is in Buddie's herbarium. 



We are certain from the Cliffbrtian herbarium, now fortunately 

 in Sir Jofeph Banks's hands, that this is the only Bromus mentioned 

 in the Hortus Clfflortianus, though the fynonyms there imply feveral
