Herb varying much in luxuriance, always considerably hairy. Stems 
spreading, branched, clothed with soft horizontal hairs. Leafits strongly 
ribbed. Flowers in round or ovate heads. Calyx very hairy, furrowed ; 
its orifice is surrounded with an elegant red and white circle when about 
half grown. Standard of the blossom red; the other petals pale red or 
white. E. Bot. (In nothing so remarkable as in the enlarged spread seg¬ 
ments of the calyx , of a rich brown colour when the seeds are ripe. El.

Starry-headed Trefoil. T. stellatum. Linn. Discovered by Mr. Ror-

(Stems numerous, spreading, often decumbent, about a foot long, branched, 
cylindrical, scored, slightly hairy. Bloss. pale red. One of those Tre¬ 
foils distinguished by the teeth of the calyx becoming remarkably leafy, 
and much dilated, as the flower fades, and the seed ripens. In this it 
agrees with T. stellatum, but differs from pratense and its allies, as well as 
from arvense, whose teeth, though permanent and rigid, do not become 
leafy or dilated. Sm. E.)
