254 LEGUMINOSZ. Mucuna. 
$ 1. Legumes roundish or oblong, 1-3-seeded, deeply furrowed along the su- 
tures ; the valves furnished with oblique lamelle or plaits that anastomose 
and form long cells on the surface.—Citta, Lour. 
n (1) M. monosperma (DC.:) perennial: leaflets ovate, when young 
pubescent, adult ones nearly glabrous: racemes short, somewhat corymbi- 
form, short-peduncled, drooping: pedicels long : lowest calyx-segments long- 
ish pointed ; the others very short and inconspicuous: legume semi-oval, ob- 
liquely plaited, 1-seeded, armed with very stiff stinging hairs: seed reniform ; 
the hilum entirely surrounding the convex margin.— DC. prod. 2. p. 406. 
(without char.) ; Wall. L. n. 5623; Wight! in Hook. Bot. misc. 2. p. 346. 
Suppl. t. 12 ; cat. n. 752.—Carpopogon monospermum, Roxb. fl. Ind. 3. p. 289. 
- —Dolichos urens, Roxb. in E. I. C. mus. tab. 286. 
782. (2) M. atropurpurea (DC.:) perennial: leaflets ovate, acuminated, 
adult ones nearly glabrous: racemes drooping, long-peduncled, sometimes. 
compound ; the floriferous portion sometimes elongated ; pedicels long, slen- 
der, compressed: calyx-segments all broadly ovate, obtuse: legume oblong- 
oval, obliquely plaited, 2- (or sometimes 1-) seeded, copiously armed with 
brown stinging hairs: seed oval, more convex on the one side, and there fur- 
nished its whole length with the linear hilum.— DC. prod. 2. p. 406 (without 
char.) ; Wall.! L. n. 5620 ; Wight! cat. n. 151.—Carpopogon atropurpureum, 
Roxb. ! fl. Ind. 3. p. 287. Courtallum. Travancore. 
It is difficult to explain in words the nature of the plaits on the legume: 
in the present species there are (always?) four series of them, proceeding 
from the apex of the fruit; each of these takes a diagonal direction from 
right to left, for about half the breadth of the pod; it then makes a turn and 
proceeds upwards, parallel to and at no great distance from the former plait, 
and after having thus reached close to the starting point, it bends its course 
in obliquely downwards: the whole plaits from the apex to the base of 
legume are formed in this way ; so that each valve might be described as 
covered with only two long obliquely anfractuose lamella. In JM. mono- 
sperma the arrangement is not quite so regular or conspicuous in our speci- 
mens, but we have no doubt of its being similar. 
$ 2. Legumes oblong, deeply furrowed along the sutures: valves even (without 
plaits ).—Carpopogon. 
783. (3) M. gigantea (DC. :) perennial : leaflets ovate, acute, adult ones gla- 
brous: flowers almost umbellate, at the apex of long pendulous peduncles: 
pedicels long, slender: three lower calyx-segments short, tooth-like; the 
others very short and inconspicuous: legume linear-oblong, tapering at the 
base into a short stalk, deeply furrowed along the sutures, not plaited, armed 
with stiff brown stinging hairs, 3-6-seeded : seeds oval, surrounded on 
more convex margin with the long linear hilum.— DC. prod. 2. p. 405 (2);

$3. Legumes linear, not sulcated on the sutures: valves without plaits.— 
Stizolobium, Browne, 
784. (4) M. hirsuta (W. & A.:) branches, petioles, racemes and under 
side of the leaflets hirsutely tomentose: leaflets ovate, upper side hirsutely 
ubescent: racemes drooping, long-peduncled ; floriferous part somew 
Ong; pedicels as short as the calyx ; calyx-segments broadly lanceolate,
