Root perennial. Stem ascending or erect, 2 — 3 feet high. Leaves 
ovate, finally serrulate, nearly glabrous. Floioers in ovate heads on short 
peduncles. Calyx and Rracteas very hairy. Corolla bright purple, much 
longer than the calyx. 
This, perhaps the most valuable species of Trifolium, is found occasion- 
ally in the low country of Carolina, like the preceding species it grows 
luxuriantly in the spring but disappears during the steady heat of summer. 
Grows in close rich soils.

Stem herbaceous, decumbent, 12 — 18 inches high, very pubescent. 
Leaves ternate, somewhat rhomboidal, pubescent, the upper ones acute, 
the lower emarginate. Petals 3 — 4 inches long. Flowers in compact, 
oblong heads, after expansion reflected; common peduncle scarcely an inch 
long. Calyx hairy, with the segments nearly equal. Vexillum of the 
corolla twice as long as the calyx, rose coloured : Wings and keel shoit, 
nearly white. Legume glabrous, compressed, slightly winged, 4-seeded. 
This species of Trifolium, which under the name of Buffalo Clover, 
grows I believe freely in the upper districts of Georgia, is rare in the 
low country. Its leaves and flowers are larger than those of any other of* 
our species. With our cattle it does not appear to be a favorite foodr
