like. Leaf simple. 

 (TENI'STA Lam. Standard oblong-oval. Keel oblong, not wholly includ- 



ing the stamens and pistils. Leaves with 3 leaflets, or, in some, simple. 

 CYiisus Dec. Standard ovate. Keel very obtuse, including the stamens 



and pistil. Leaves, in all, with 3 leaflets. 

 ADENOCA'RPUS Dec. Stamens with the filaments connate. Legume bear-

 ONO X NIS L. Calyx with 5 linear segments. Standard striate. Legume 



containing few seeds ; in most, turgid. 

 AMO'RPHA L. Corolla consisting of the standard only.

 connate in one of three modes; the 10 connate; 9 connate and one 

 distinct; or connate by fives: in a few cases all are distinct. Legume 

 dividing transversely into 1-seeded joints, called loments. Embryo with 

 the radicle beside the edges of the cotyledons, which are flattish, and, in 

 germination, are converted into leaves furnished with stomata. Leaves 

 simply pinnate, or simple. 



COROM'LLA AVr/-. Calyx campanulate, usually shorter than the claws 

 - of the petals. Carina acute. Stamens diadelphous. Seeds ovate, or 

 cylindrical.
