238 LEGUMINOS JE. Ruyncnosia. 
(9 and 1). Ovary 1-2-ovuled. Style glabrous. Legume obliquely ovate 
or oblong, or falcate, slightly compressed, 1-2-seeded. Seeds with a carun- 
eulus at the hilum.—Usually twining perennial or shrubby plants. Leaves 
generally pinnately trifoliolate, rarely simple. Flowers yellow, axillary, ra- 
cemose or solitary. 
This pou, as it stands in De Candolle’s prodromus, contains several species that 
are much at variance with the generic character there given ; and, on the other hand, 
there is nothing in that character to separate it from Dolichos and some other ge- 
nera. We have already separated one genus, and perhaps the followin subgenera 
are equally distinct. R. virgata, Graham ! in Wall. T n. 5503 (with which Crotalaria 
tuberosa of Don and De Candolle is the same), obviously belongs to neither of these 
genera; it is Pyrrhotrichia tuberosa, herb. Arn. : the calyx is much shorter than the 
corolla, about equally 5-cleft, the segments triangular and acute; the vexillum has 
a callous ring at the base of the limb, and the spurs each a membranaceous appen- 
dage; the fruit resembles that of Nomismia, to which genus it is allied in character, 
but not in habit. 
Subgen. 1. Evruyncnosta. Calyx-segments acuminated or subulate, the 
lowest one the longest. Keel falcate. Ovary 2-ovuled. Legume 2-seeded. 
Hilum and carunculus small.—T wining plants. 
a. Bracteas minute or wanting: calyx shorter than the corolla : legume scimitar- 
shaped, several times longer than the calyx. 
731. (1) R. velutina (W. & A.:) twining; branches, petioles, and pe- 
duncles, softly pubescent: leaves trifoliolate ; leaflets roundish, cuneate at 
the base, mucronate ; upper side slightly and softly pubescent ; under hoary 
with a soft short tomentum, without glands: peduncles axillary, 1-2-flower- 
ed ; flowers on longish pedicels: calyx somewhat campanulate ; middle seg- 
ment of the lower lip subulate, faleate upwards, a little shorter than the 
keel ; other segments lanceolate, nearly twice as short as the lowest one: 
vexillum very pubescent on the outside, eglandular, marked on the inside 
above the claw with two small gibbous projections : legume scimitar-shaped, 
attenuated at the base, pubescent, (about 14 lines long by 4 broad), 2-seed- 
ed.— Wight ! cat. n. 832. Negapatam. 
732. (2) R. nuda (DC.:) twining; branches, petioles, and racemes, pu- 
bescent: leaves trifoliolate ; leaflets cuneate-roundish, rounded or retuse, 
nearly glabrous on both sides except the pubescent nerves beneath, not dotted 
with glands: racemes filiform, few-flowered, longer than the leaves ; flowers 
distant, very Shortly pedicelled, deflexed : calyx-segments subulate, the 
lowest one a little longer than the others ; vexillum nearly glabrous, scarcely 
(or inconspicuously) dotted with glands, without gibbous projections on the 
inside: legume pubescent, scimitar-shaped, attenuated at the base, (about 7 
lines long and 2 broad), 2-seeded.— DC. mem. leg. p. 366 ; prod. 2. p. 385 
(where by mistake the leaves are said to be dotted) ; Wight! cat. n. 831 
(partly).—Hedysarum nudum, Rotti. 
This is only to be distinguished from the following by the want of glandu- 
lar dots on the under side of the leaves ; and although we retain it, we must 
remark that it seems to be a very doubtful species ; the presence and absence 
of glands, size of the leaves, and the length of the racemes, being characters | 
subject to much variation, according to the soil and exposure. e have be- 
fore us a label in Rottler's handwriting, but in the distribution of No. 831. 
it may have been attached to a specimen not from Rottler: the specimen 
along with it, however, and from which we have taken our description, agrees 
with the character given by De Candolle in his Mem. sur les Legum., p- 366. 
We rather suspect that Rottler did not intend to distinguish it from the next.
