Root slender, tapering. Stems several, from six to ten inches 
long, round, branched, ascending, clothed as is the rest of the plant 
with soft pubescence. Leaves alternate, on short stalks, leaflets ob- 
cordate, unequally toothed, the mid-rib stout, and the lateral veins 
prominent. Stipules large, broadly ovate, pale, thin, and membra- 
nous, veiny, toothed on the margin, and hairy. Inflorescence a 
globose head of crowded flowers, elevated on a peduncle. Calyx 
very downy, ten ribbed, its teeth when in flower bristle-shaped, erect, 
longer than the corolla, in fruit much enlarged and dilated at the 
base, becoming veiny, and spreading in a star-like manner, its mouth 
closed with a tuft of hairs. Corolla small, pink, concealed by the 
calyx teeth. Legume inclosed in the calyx, containing a single pale 
ovate seed. 
Habitat—Sea shore, Sussex, between Shoreham harbour and the 
sea, abundant. 
Annual ; flowering in July and August. 
This curious species of Clover, it is supposed, has been introduced 
and become naturalized. It is frequent in Italy, but is by no means 
confined to the sea shore, but is, perhaps, more common in moun- 
tainous districts than near the sea. It docs not appear to possess 
any agricultural merits.

nous, downy, ribbed. Inflorescence terminal cylindrical heads of 
numerous crowded flowers, elevated on a slender peduncle. Calyx 
sub-cylindrical, ten ribbed, very downy, its teeth bristle-shaped, erect 
in flower, spreading in fruit. Corolla small, pink, inconspicuous. 
Legume inclosed within the calyx, single seeded, 
Habitat.—Corn fields, dry pastures, and waste places ; common. 
Annual; flowering in July and August. 
This common species is a pretty ornamental plant, producing an 
abundance of its pink soft downy heads. It does not appear to be a 
plant selected as food by any class of animals, nor is it applied to any 
other use than as an ornamental plant for adorning chimney pieces
