pubescent on the back, greenish yellow, the basal lobules remote from the claw and 
subacute, the claw about 3 mm. long, obliquely inserted, the blade about 13 mm, 
long and 13.2 mm. broad; wings and keel purplish or light mauve, the former oblong, 
auriculate on the vexillar side, truncate-obtuse at the apex, sparsely villous along 
the carinal side down to the claw, adhering to the carina, 
the claw 4.5 to 5 mm. long, the blade 10 mm. long, 4.5 
mm. broad; carinal petals falcate, convex, subacute, au- 
riculate, plicate, slightly cohering, pubescent without 
along the carinal side and on the claw and within at the 
base of the blade, the claw 5 mm. long, the blade about 
10 mm. long and 3.5mm, broad. Staminal tube broadly 
dilated at the base, sparsely hairy along the vexillar 
side; upper end of the filament villous; vexillar stamen 
free at the base. Ovary linear, somewhat attenuate at 
the base, densely villous, about 7 mm. long, 8-ovulate; 
style arcuate, villous at the base; stigma inconspicuous. 
Legume stipitate, acute at the apex, 3 to 8 cm. long,

A small tree, the branchlets, rachises of the leaves, and those of the inflorescences 
more or less ferruginous-pubescent, the bark of the branchlets brownish or grayish, 
lenticellate. 
Leaves 7 to 13-foliolate, the rachis 7.5 to 11 cm. long, canaliculate, the groove 
broader at the insertion of the leaflets, the pubescence dense at first, more or less 
evanescent later. Leaflets coriaceous, the costa and veins deeply impressed above, 
prominent beneath, the petiolules 4 to 6 mm, long, more or less ferruginous-hairy, 
obscurely canaliculate, the blades ovate, obovate, or oblong, rounded at the base, 
rounded-obtuse or shortly obtuse-acuminate at the apex, 3.5 to 9 cm. long, 2.5 to 
3.5 cm. broad, minutely puberulous above at first, glabrous at later stages, minutely 
pubescent, principally on the costa and veins, beneath. Stipules ovate, obtuse, 
densely ferruginous-hairy, about 3 mm. long, caducous. 
Racemes solitary in the axils of the upper leaves, the rachis (velvety-hairy at first, 
glabrous in fruiting specimens) 9 to 24 cm. long. Peduncles and pedicels densely 
ferruginous-pubescent, the former solitary, or 2 or 3 together and then 2-flowered, 
about 3 mm. long, the latter 2 to 4 mm. long; bracts and bractlets ovate-orbicular, 
the latter opposite and approximate to the calyx. Calyx cupulate, subtruncate or 
remotely sinuate-toothed, about 5 mm. long, densely ferruginous-pubescent without. 
Petals pinkish or purplish; standard suborbicular (broader than long), biauriculate 
and callous at the base, emarginate at the apex, flat, the claw 2.5 mm. long, the blade 
11.5 to 12 mm. long, 14.5 mm. broad, densely silky-pubescent without, and within 
above the claw; wings adhering to the carina, rounded-auriculate at the base on the 
vexillar side, obtuse at the apex, slightly silky-pubescent without, the claw 4.5 mm.
