Lizard Point; the cultivated crimson variety has only established itself in 
a few places in southern England, 7. swmmer. 
2, Trarvense, Linn. (fig. 246).  Hare’s-foot Clover.—A slender, 
branching, erect annual, seldom reaching a foot in height, and clothed 
with short soft hairs. Stipules and leaflets narrow. Flowers small, in 
pedunculate heads, which are at first nearly globular but soon become 
oblong or cylindrical, 6 to 9 lines long, appearing very soft and feathery 
owing to the fine hairy teeth of the calyx projecting beyond the very small 
corolla. 
In cornfields, dry pastures, on sandy banks, etc., throughout Europe and 
western Asia, except the extreme north. Abundant in Britain, but more 
in the south than in the north. JU. summer and autumn. 
3. ©. stellatum, Linn, (fig. 247). Starry Clover.—A low but rather 
coarse annual, covered with soft hairs, and seldom above 6 inches high. 
Leaves broadly obovate or obcordate. Flower-heads globular, softly hairy, 
on rather long peduncles above the last leaves. Calyx remarkable for the 
long subulate-lanceolate teeth, spreading like a star after flowering, whilst 
the mouth is closed over the pod by a tuft of hairs. Corolla shorter than 
the calyx-teeth, of a pale cream-colour. 
In dry pastures and waste places, in southern Europe, common round 
the Mediterranean, reappearing in south-western France, and in Britain, 
on the coast of Sussex near Shoreham, and perhaps ina few other localities, 
introduced with ballast. #7. early summer, and sometimes again in 
autumn. 
4, 'T. ochroleucum, Linn. (fig. 248). Sulphur Clover.—A perennial, 
with the habit and foliage as well as the inflorescence of Z. pratense, and 
the same-sized flowers, but the leaflets are usually rather narrower, the 
flower-heads more ovoid, and the flowers cream-coloured, with rather 
shorter teeth to the calyx, the lowest tooth twice as long as the others. 
In pastures, dry meadows, and open woods, in central and southern 
Europe to the Caucasus, but not crossing the Baltic. In Britain, confine 
to a few of the eastern counties of England. FU. summer. 2 
5. T. pratense, Linn. (fig. 249). Red or Purple Clover.—Stock 
usually perennial, but of few years’ duration. Stems decumbent or nearly 
erect, 1 to 2 feet long, and hairy. Stipules rather large, ovate, veined, 
with long green points. Leaflets obovate or obcordate. Flowers of a 
reddish purple, about 6 lines long, in dense terminal, ovoid or globular 
heads, with 2 sessile, trifoliolate leaves close at their base, or very rarely 
the heads are shortly stalked above them. Calyx-teeth subulate and hairy, 
the lowest longer than the others. After flowering the petals turn brown, 
the calyx remains erect, enclosmg the pod, which has usually a single 
seed. 
In meadows and pastures, throughout Europe and central and northern 
Asia, from the Mediterranean to the Arctic Circle, ascending high up into 
mountain regions. It has however been so long cultivated, that in some 
localities it may not be truly indigenous. Abundant in Britain. FJ. the 
whole summer. [The only presumed indigenous state of this plant is a 
small one with a shorter corolla, Var. parviflora, Bab. |
