THE root is perennial, fibrous: the stem is herbaceous, climbing, 
cylindrical, hairy, divided into many branches, which twist round 
the neighbouring trees, and rise to a considerable height: the 
leaves are ternate, and stand upon long footstalks, placed alter- 
nately at the distance of a foot from each other: each pinna, or 
lobe, is entire, ovate, pointed, smooth on the upper side, on the 
under hirsute; the lateral lobes are oblique, and somewhat larger 
than that in the middle, which is of a rhomboidal shape: the: 
proper footstalks are short, and furnished with small stipulae: the 
flowers are large, of a purplish or viclet colour, and placed mostly 
in ternaries upon short peduncles, and form pendant spikes, which. 
arise from the axillz of the leaves, and are about a foot in length: 
the calyx is bell-shaped, gibbous at the base, lax, downy, divided 
into two lips, of which the upper is semi-ovate ;. the under separates. 
into three lance-shaped segments: the corolla is of the papiliona- 
ceous order, consisting of a vevill:um (standard) which is roundish, 
entire, concave, obtuse, and double the length of the calyx: two. 
aie (wings) which are oblong, obtuse, concave, and iwice the 
length of the vexillum; a carina (keel) which is scythe-shaped, 
of the length of the ala, compressed, and at the apex furnished 
on each side with a short concave spur: the filaments are ten, 
nine of which are united at the base; they are alternately longer 
and shorter; the former are four times the breadth of the others, 
and supplied with incumbent anthere; but the anthera of the 
Jatter are placed vertically: the germen is oblong, villous, and 
supports a slender style about the length of the filaments, termi- 
nated by a small orbicular stigma: the fruit isan oblong pod, in 
the form of the letter /; four or five inches in length, diteied with
