86 XLII. LEGUMINOS&. 
straight, the 2 uppermost somewhat connate. Standard re- 
flexed; keel very obtuse, longer than the wings. Stamens 
diadelphous. Ovary sessile, several-ovuled; style subulate, 
glabrous; stigma obtuse. Legume turgid, about 6-seeded, 
constricted between the seeds, 2-valved. Seeds ovate, stro- 
phiolate, with a linear hilum.—FV. Cap. i. p. 247. 
A twining, strong-smelling, viscidly hairy shrub. Leaves pinnately 3- 
folioled, the terminal leaflet remote. Racemes axillary ; flowers yellow, 
the keel tipped with purple.—Common in the Western districts. 
58. RHYNCHOSIA, Lour. 
Calyx bell-shaped, mostly oblique, 4-5-fid, the 2 upper lobes 
more or less united, the lowest longest. Petals nearly of equal 
length or the wings shorter; standard obovate or orbicular, 
mostly with 2 minute, inflexed ears at base, naked or 2-callous 
within ; wings narrow, eared at base; keel broader, incurved, 
obtuse or subrostrate. Stamens diadelphous ; the vexillary 
filament quite free, mostly knee-bent. Ovary subsessile, with 
2 ovules ; style incurved beyond the middle, quite glabrous 
and mostly thickened above, filiform and often hairy at base. 
Legume compressed, oblique or falcate, rarely septate within. 
Seeds 1-2, compressed with a lateral short or oblong scar, and 
a subcentral seed-cord.—F7. Cap. ii. p. 247. 
Climbing or prostrate, rarely erect, herbs or undershrubs, mostly sprinkled 
with resinous dots, natives of warm countries. Leaves commonly pinnately 
3-foliolate, rarely 1-foliolate or pinnate, or 2-3-pinnate, plurijugate. Pe- 
duncles mostly racemose, rarely umbelled or 1-flowered. Flowers yellow, 
streaked with brown, rarely purple-—About 30 South African species (some 
new undescribed), dispersed, but chiefly Hastern. 
59. ERIOSEMA, DC. 
Calyx bell-shaped, 5-fid, the upper lobes sometimes connate. 
Petals subequal; standard obovate or oblong, with inflexed 
ears at base ; wings narrow, longer or shorter than the wider, 
incurved, obtuse keel. Stamens diadelphous. Ovary sessile, 
very hairy, 2-ovuled ; style filiform, quite glabrous above the 
middle, ineurved and often thickened upwards; stigma small 
or capitate. Legume compressed, obliquely orbicular-rhom- 
boid or broadly oblong, hairy. Seeds 2-1, compressed, oblong, 
obliquely transverse, the seed-cord fixed at one end of a linear 
sear.—LH1. Cap. ii. p. 258. 
Erect or prostrate, rarely twining, herbs or undershrubs of warm countries. 
Foliage and inflorescence of Rhynchosia, to which this genus is closely 
allied, and from which it is known by the obliquely transverse seeds and 
the excentrical seed-cords ; a character easily seen in the unripe fruit.— At 
least 9 Cape species, all Eastern or from Natal or Transvaal.
