Rhynchosia. | LEGUMINOS& (Harv.) 255 
Has. Port Natal, 7. Williamson! (Herb. D., Hk, Bth.) 
The whole plant is very pale green, the stems, petioles, and inflorescence softl 
downy. Stems slender, striate, stipules very small and withering. Petioles 14 in 
long. Leaflets 1-1} inch long, the Secintndl on a petiole 3—4 lines long, wider than 
long, generally acute, lateral oblique, all pale green, the younger puberulous above, 
the old becoming glabrous. Flowers yellow, 5-6 in a lax raceme, 6 lines long. 
Pedicels slender, 1-2 lines long. Calyx 4-5 lines long, very pale, densely black- 
dotted, the segments taper-pointed. Legume sometimes minutely downy, (the un- 
ripe) 9-10 lines long, 3 lines wide, acute, tapering at base, and almost stipitate. 
22. R. gibba (E. Mey.! Linn. 7. p. 170); voluble or prostrate, thinly 
pubescent ; petioles longish, leaflets ovato-rhomboid, acute or obtuse, 
membranous ; stipules minute ; racemes longer than the leaves, laxly 
several flowered ; upper calyx-segments short and broad, acute, lowest 
conspicuously longer, subulate ; vexillum glabrous ; legume falcate, much 
longer than the calyx, thinly pilose (or hirsute). #. & Z.! 1667; also

Stems several, climbing or trailing, elongate, slender, mostly densely and shortly 
pubescent. Petioles uncial, the terminal leaflet remote. Leaflets very variable in 
form, sometimes almost orbicular and very obtuse, sometimes rhomboid-acuminate, 
the lateral very unequal-sided, 4-1} inch long and broad, pale or darkish green. 
Peduncles 34 inches long, floriferous above the middle ; flowers 6-8 lines long, the 
ovate vexillum streaked with brown. Ovary very hairy. Legume 12 lines long, 4 
lines wide, acute at each end. The common form is well characterized by its 
Glycine trilobaand G. secunda, Thund./ both seem to belong to this species, but the 
specimens in Herb. Upsal are very imperfect. 8. has thicker, somewhat rugulose 
leaflets, pale underneath, and the upper calyx-lobes are longer and narrower. It 
closely approaches R. argentea, but differs in the vexillum. 
23. BR. puberula (Harv.) ; prostrate or subvoluble, nearly glabrous 
or silky-puberulous ; petioles very short ; leaflets elliptic-oblong or ob- 
long, rigid, netted-veined; stipules lanceolate, striate, patent; pedun- 
cles 1-2 flowered, shorter than the leaves; calyx villous, its segments 
longer than the tube, shorter than the glabrous vexillum ; legume 
sessile, very villous. Copisma tottum, E. Mey.! Comm. p. 133. Eriosema

Root thick and woody. Stems several, spreading every way, 1-2 feet long, chiefly 
branched near the base, flexuous, mostly thinly covered with long, white, slender 
hairs. Stipules brown, narrow, 1-1} lines long. Petioles 1-2 lines, rarely 4-6 lines 
long. Leaflets 1-11 inch long, 4-8 lines broad, always longer than broad, but vari- 
able in shape and proportions, green on both sides and conspicuously netted. Flowers 
4 lines long. Legumes 6-8 lines long, 3-4 lines wide, oblique but not falcate ; seed 
‘ oblique, subtransverse, nearly as in Eriosema, but the hilum is medial, not linear.
