BRITISH GRASSES. 513

natifid ; lobes all entire ; lower linear ; terminal lobe broader and 
elongated. Sepals linear-lanceolate, acute, nearly as long as the 
petals. Petals pale yellow, deeper within, upper pair just touch- 
ing each other, lowest broadly obovate, marked at the base with 
five faint lines. Spur yellowish, gradually narrowed to a blunt 
apex, slightly exceeding the calycine appendages.—V. sabu- 
losa: Root long, slender, and fibrous. Stems slender, czespitose. 
Leaves hairy, somewhat fleshy ; lower ovate, lanceolate, crenate ; 
upper narrower. Stipules pinnatifid; marginal lobes linear, en- 
tire ; terminal lobe larger than the others and broader, bluntly cre- 
nate or nearly entire. Sepals lmear-lanceolate, narrowed gradu- 
ally to the apex, nearly as long as the petals. Petals larger than 
in the preceding; upper pair purplish, and slightly overlapping ; 
lowest yellowish, within purple at the circumference, broadly 
obovate, marked below with five purplish lines; spur purplish, 
narrowed gradually to a blunt apex, exceeding considerably the 
calycine appendages. 
From V. rothomagensis of Desfontaines, as represented in my 
collection by the plant of Rouen, sabulosa differs by the smaller 
proportion which its sepals bear to its petals, the smaller size of 
all its parts, by its less hispid stem and leaves, and by the crenate 
terminal lobe of its stipules. V.rothomagensis, of the ‘ Flora 
Tonbridgensis,’ according to an authenticated specimen from 
Mr. E. Edwards, is only one of the forms of tricolor ; but of 
these more hereafter.

The author of this useful work, in his general observations on 
the subject, states that “about 2000 species of Grasses are said 
to have been already collected. Dr. Lindley computes that their 
ratio to all other phzenogamous plants is as one to twenty: of 
these, 116 are indigenous to the British Isles, 96 to Scotland, and 
82 to Ireland.” The British Grasses are rather understated at
