south of Europe, and was introduced in 1822.

5 — TRIFOLIUM REFLEXUM, Lin. THE BUFFALO CLOVER 
Engraving. — Bot. Mag. t. 3471. 
Spfcipic Character. — Plant pilose ; stems ascending; leaflets obo- 
vatc, serrulated ; stipules foliaccous, obliquely-cordate, acuminated ; 
heads of flowers globose, axillary ; flowers on long pedicels, at length 
Description, &c. — This very handsome species has the flowers in heads, like those of the common clover, 
but very much larger. The flowers are pink and white, the standard being pink, and the wings and keel of a 
pure white. It is a native of Virginia and Mexico, and it was first introduced in 1794 ; it was, however, soon 
lost, and was not re-introduced till 1835, when it was sent by Mr. Drummond from Texas. It is quite hardy 
in the open air in Britain, and will grow in any common garden soil. 
C— TRIFOLIUM SPADICEUM, Lin. THE BAY-COLOURED CLOVER. 
Engraving. — Bot. Mag. t. 557. 
Specific Character. — Stem erect, almost simple, slender ; leaves 
stalked; leaflets oblong, ovate, sessile, denticulate; stipules leafy, 
naiTow, acuminated ; heads of flowers ovoid, on peduncles ; vexillum 
obcordate ; calycinc segments unequal ; the lower ones long and pilose, 
the two upper ones small and glabrous ; legume ovoid, compressed, 
one-seeded ; seeds irregularly egg-sh.aped, bay-coloured ; radicle promi- 
nent. 
Description, &c. — A very curious little plant, with delicate foliage and rich chestnut-brown spikes, crowned 
with golden yellow flowers. It is a native of most parts of Europe, but not of Great Britain, to which country 
it was introduced in 1778. It is quite hardy, and only requires to be planted in the open border. It is generally 
propagated by seeds, which it ripens in great abundance.

Description, &c. — This very singular plant produces its bright rose-coloured flowers in a kind of crest, 
which gives it a very singular appearance. It also diflfers from the other species in having five, and sometimes 
seven, leaflets instead of three; and in having a long fusiform root. It was introduced in 1763 from Siberia, 
and it has since been often lost and re-introduced, as it is very difiicult to keep, from being only propagated by 
seeds, which seldom ripen. In other respects it is quite hardy.

the tenth one is sometimes connected with the others at tho base. 
Legume length of calyx, valveless, one-seeded, sometimes ending in a 
beak. (G. Don.) 
Generic Character. — Sepals five, joined together to the middle 
into a five-cleft, permanent calyx, with the tube usually beset with 
glands ; the lobes acuminated, having the lower one a little more 
lengthened out than the others. Stameus ten, usually diadelphous j 
Description, &c. — The peculiarity of plants belonging to this genus consists in their being all more or less 
warted with glandular tubercles ; and from this the genus takes its name, Psoralea signifying warty or scurfy.
