dilated at apex into a short cup. Calyx inserted with corolla and 
stamens at tup of tube; lobes 5, deep membranous unequal; superior 
lobes connate to a greater height, broader; lowest narrower; esti- 
vation much imbricated. Petals unequal or nearly equal; standard 
orbicular ; wings obliquely oblong; keel curved subrostrate. Sta- 
mens 10; filaments l-adelphous; tube closed below; anthers 5 
longer subbasifixed ; 5 short, often subglobose, versatile, either all 
fertile or 2, 3 sometimes minute or entirely abortive. Germen 
inserted in bottom of tube, subsessile; ovules few; style slender 
elongated, minutely stigmatiferous at apex, finally breaking off a little 
above base or at middle; lower part persistent, often dilated recurved. 
Legume sessile; segments 1, 2, reticulated or muricated, 1-seeded. 
Seeds compressed lenticular exarillate-— Herbs, often rigid or viscous ; 
leaves pinnate 3-foliolate ; stipules adnate to dilated base of petiole ; 
flowers’ 1, 2 in axil of each bract, in dense, cylindrical or capituliform, 
terminal or more rarely axillary, spikes; bracts similar to leaves, 
and furnished with 2 adnate stipules, usually 1-foliolate by abortion 
of lateral leaflets? (Zropical Asia and Africa, northern and tropical 
America’).

unequal ; 2 superior longer, connate to a greater height, 2 lateral 
usually smaller ; lowest oblong or lanceolar, nearly equal to superior.

curved, rather obtuse or subrostrate. Stamens 10, 1-adelphous; 
anthers of 2 forms; 5 subbasifixed longer, 5 alternate versatile. 
Germen sessile; ovules «©; style slender; apex minute stigmati- 
ferous. Legume compressed ; sutures 2, generallydissimilar ; inferior 
usually sinuate; segments oc, glabrous or echinate, indehiscent.
