 stipellate. Flowers in axillary racemes, solitary or twin along the 

 rhachis, rarely solitary in the axils of the leaves ; bracts caducous ; 

 bractt'oles 0. Calyx-teeth not accrescent, the 2 upper more or less 

 connate. Coi'oUa included or exserted ; standard obovate or orbicular 

 with inflexed auricles at the base ; wings narrow ; keel incurved at the
