82 ADDITIONS TO THE BRITISH FLORA. 
specimens found at Claygate, L. multiflorum may be known 
rom L. perenne, by growing in close tufts of many straight 
stems from the same root, half a yard and more in height. 
The colour of the whole plant, and especially of the flowers, 
is paler; the spikelets bear more numerous flowers, and theif 
glumes have mostly long awns. But I have seen Lolium pe- 
renne, in its awnless state, bearing as many flowers in the 
spikelet, as do several of the Claygate specimens; and the 
awned form of L. perenne above mentioned, as found a 
Moulsey, has the awns rather longer than some of the spe 
cimens from Claygate. It is possible that the Moulsey spe ` 
cimens would be called L. Boucheanum, by Kiinth ; but they ` 
were growing among plants of the ordinary L. perenne, and 
differed only in having awns on most of the glumes. On - 
the whole, I am disposed to think that ZL. multiflorum may : 
stand as a species, on account of its alleged annual root, its ` 
upright and tufted growth, and usually long awns. In thè 
Flora Italica, of Bertolini, it is given as a variety of L. perennt; ` 
and L. Boucheanum quoted as a synonym; yet Künth and ` 
Koch both describe the last as a perennial grass, and L. mul- | 
tiflorum as annual. 
3. Bromus commutatus. (Schrader.) 
This is an old acquaintance under a new name, and not : 
really a new plant to Britain. In a well developed state It 
has been almost universally called Bromus arvensis, while ` 
a less luxuriant condition it has been confused with a non- - 
pubescent variety of Bromus mollis, under the name 
romus racemosus. The specimens received from the Bo 
tanical Societies of Edinburgh and of London, and from 
various individuals, under the name of B. arvensis, all provê 
to be B. commutatus; and as Smith had evidently com ` 
founded the two species, all his specimens of the true B 
arvensis being foreign, I begin to doubt whether the lattet 
has ever been found wild in this country. I had long bee? - 
puzzled by receiving what appeared to be specimens of the
