This is certainly the G/ye. Pondicheriensis of Sprengel, and we have no 
doubt of its being also G. rufescens of Willdenow. Sprengel’s description of 
a plant under the latter name in Willdenow's herbarium is no doubt slightly at 
variance, in as far as he states the stem to be erect and the legumes glabrous ; 
but the former appears to twine but very slightly, and perhaps only at the 
extremities, and the legume, when old, has much of the pubescence rubbed 
off: it is possible, however, that the plant in the herbarium is not that origi- 
nally described, (for Willdenow does not seem to have had a specimen when 
he published the genus Glycine in his spec. plant), and we are almost certam 
that ours is the plant of Rottler. It is very variable in the quantity and co- 
lour of its pubescence. 
736. (6) R. (Ph.) Heynei (W. & A.:) diffuse, with the extremities slender 
but scarcely twining, densely and softly pubescent : leaflets ovate ; upper side 
nearly even, under with prominent nerves and transverse, veins : peduncles 
axillary, bearing 1-2 fascicles of short pedicelled flowers : fascicles distant, 
few-flowered, subtended by a roundish cordate bractea: calyx-segments 
cordate-oblong, obtuse, nearly as long as the legume : legume oblong, with a 
short oblique point, 2-seeded, constricted and with a cellular partition be- 
ed the seeds, pubescent.—Cylista reticulata, Heyne! in Wall.! L. n. 
Whether this be retained in Rhynchosia, or be separated with R. rufescens, 
the specific appellation given by Heyne is totally inapplicable when com- 
pared with its congeners. 
Subgen. 3. Prycnocentrum. Calyx 4-cleft ; segments acuminated, nearly 
equal ; upper one bifid. Vexillum with the margins of the spurs and of the 
claw folded in: keel faleate. Ovary 2-ovuled. Legume sessile, oblong, 2- 
seeded. Seeds with a large fleshy bifid caruneulus.—Erect shrubby pubes- 
cent plants. Leaves trifoliolate, dotted. Peduncles 1-2-flowered. 
_ 491. (7) R. (Pt.) suaveolens (DC.:) shrubby, erect, covered all over with a 
viscous pubescence : extreme young branches sometimes slender and diffuse, 
but scarcely twining: leaves trifoliolate ; leaflets broadly ovate, acute or 
acuminated, inconspicuously dotted on the under side with yellowish glands: 
peduncles 1-2-flowered, filiform, jointed, and with a bractea at the separa- 
tion of the pedicels : calyx deeply bilabiate ; segments long-subulate, curved 
upwards, nearly as long as the corolla : legume a little compressed, pubescent, 
2-seeded, contracted and with a cellular partition between the seeds.—DC.

_ This is almost the only instance that we know (R. Heynei being another) 
in Rhynchosia of a legume with a cellular partition between the seeds ; but 
notwithstanding that structure, we consider it more allied to the followmg 
species than to the plants with which Dr Graham has associated it: it is, 
however, an additional proof of the necessity of separating this subgenus. 
738. (8) R. (Pt.) cana (DC.:) shrubby, quite erect, pubescent : leaves 
trifoliolate ; Pda on the older oec Pradig peior or acumi- 
nated, on the young shoots oblong-lanceolate acuminated, minutely dotte 
with resinous glands on both sides ; upper slightly pubescent ; under dense- 
ly pubescent or almost velvetty, rugose and reticulated with the nerves and 
veins : peduncles axillary, 2-flowered, filiform, with a small bractea and j 
at the separation of the pedicels: calyx 4-cleft to the middle, scarcely bila-
