dilated at apex into a short cup. Calyx inserted with corolla and 

 stamens at top of tube ; lobes 5, deep membranous unequal ; superior 

 lobes connate to a greater height, broader ; lowest narrower ; aesti- 

 vation much imbricated. Petals unequal or nearly equal ; standard 

 orbicular ; wings obliquely oblong ; keel curved subrostrate. Sta- 

 mens 10; filaments 1-adelphous; tube closed below; anthers 5 

 longer subbasifixed ; 5 short, often subglobose, versatile, either all 

 fertile or 2, 3 sometimes minute or entirely abortive. Gormen 

 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 aclnate to dilated base of petiole ; 

 flowers 1 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 aclnate stipules, usually 1-foliolate by abortion 

 of lateral leaflets- {Tropical Asia and Africa, northern and tropical
