 plus minus coalitis. Corolla papilionacea ; vexillo lateralibus reflexis ; alis antice infra medium 

 externe foveolato-plicatis, postice superne conglutinatis ; carina acuminata, genitalia includente ;

 subulatis pubescentibus ; floribus purpureo-cseruleis, racemis elongatis ; calycibus bracteatis, 

 labio supcriore-obsolete dentato inferiore, acuto integerrimo ; pedunculis calyce brevioribus. 



Shrub covered with silky hairs, erect ; leaves longly petiolate, upper surface smoothish, under
