 than them and the keel, without callosities : alae oblong- linear, 

 connivent, sometimes slightly cohering together by their spurs

 falcate in the upper part, terminated by a smooth polished acute 

 beak. Stamens diadelphous (9 and 1), alternately longer: an- 

 thers alternately longer and ovate. Style long and slender ; its
