Leaflets small, 2 to 3.5 cm. long, obtuse at both 



ends. 



Leaflets usually 3 or 4-jugate, obovate or 

 oval-roundish, rounded at the top, glands 

 between the leaves; racemes few-flowored; 

 pedicels 3 to 6 mm. long; legume coria- 

 ceous, dehiscent along the sutures. 



Leaflets usually 5-jugate, oval or ellipticalj 

 rounded at the top, a gland between the 

 lower leaves; racemes long and many- 

 flowered; pedicels 2 to 3 cm. long. 



Leaflets large, ovate-oblong or ovate-lanceolate, 

 acuminate, 5 to 8 cm. long; petiole with ob- 

 long glands between the leaflets; legume te- 

 rete. 

 Legume flattened-compressed, membranous, bivalved, 

 convex; seeds compressed j)arallel to the dissepiments; 

 petiole with obtuse glands near the base. (Section 

 Oncolobium Vog.) 

 Leaflets 4 or 5-jugatej ovate or elliptic lanceolate, 2.5 

 to 5 cm. long. 

 Legume compressed-tetragonal, linear; seeds compressed 

 parallel to the valves, their larger diameter likewise 

 parallel to the valves. (Section Phososperma Vog.)

 to 5 cm. long; legume 10 to 20 cm. long, 4 to 6 mm. 



wide. 



Legume flat-compressed^ bivalved; seeds compressed 

 parallel to the valves, with their longer diameter trans- 

 verse to them. (Section Ohamaesenna DC.) 



Legume winged with a broad longitudinal wing on 

 each valve; leaves 30 to CO cm. long; leaflets 9 to 

 12-jugate, oblong, truncate at the subsessile biu^e, 

 7.5 to 17.5 cm. long; petiole 3-angular, eglandular. f). C. alata 



Legume not winged. 



Leaves very small; leaflets 5 to 15-jugate, obo- 

 vate-oblong, ciliato on the margins, otherwise 

 glabrous; leaves fasciculate at the nodes; le- 

 gumes narrow. 

 Leaves nuich larger, pilose; leaflets 3 to 5-jugate, 

 rarely 2-jugatc, broadly oval-oblong, very ob- 

 tuse, upper surface pubescent, lower surface 

 tomentose, eglandular; legume coriaceous, 

 linear, straight, glabrous, tumid at the mar- 

 gins. 

 Stamens 10 or fewer, all perfect, similar and but slightly une- 

 qual (rarely 2 or 3 abortive); anthers linear; pedicels soli- 

 tary, in pairs or fascicles, axillary or superaxillary ; common 

 peduncle very short; legumes flat, linear, elastic, 2-valved.
