30 Mr. Woops on the Genera of European Grasses. 
European species, which is united by Kunth to Sporobolus, but it wants the 
soluble pericarp so remarkable in that genus. There is some difference of 
appearance between this plant and Agrostis, to which, however, it perhaps 
might be reunited without impropriety. 
Of AGrosris Palisot de Beauvois makes 5 genera. Agraulos, palea only 1, 
awned. Trichodium, palea 1, unarmed. Agrostis, paleæ 2, the outer one 
awned. Vilfa, paleæ 2, unarmed; and Apera (Agrostis spica venti), which is 
separated on account of the almost terminal position of the awn. 
Sir J. E. Smith says that the corolla in this genus is usually larger than the 
calyx. In all the species which I have had the opportunity of examining, 
except in A. spica venti and A. interrupta, forming the genus Apera of Palisot 
de Beauvois, the corolla is decidedly smaller than the glumes. Kunth says, 
“glume florem plerumque multo superantes, and the figures of Palisot de 
Beauvois and of Reichenbach agree in representing the corolla as smaller than 
the calyx. 
CorEANTHUS is a delicate little Grass, of which we know only one species, 
and this seems to be confined to Bohemia. It cannot be confounded with any 
other, nor, I think, joined to any other tribe. 
Kunth places KwaPPra among the Phalarideæ ; of course it would in that 
case belong to the division of the tribe which I have s 
of imme but on the whole, I have preferred numbering it among the 
Agrostideæ in spite of the peculiarity of it 
s inflorescence,—a eculiarity which 
has induced Sir W. Hooker to place it a : t

is very thin and tender, truncate and lacerate at the top, 
sort of shagginess, which seems rather to consist of to 
substance than of hairs.
