Observation. Root apparently both annual and 

 perennial, (perennial by cultivation.) Stems nume- 

 rous and decumbent, a little pubescent, scarcely ex- 

 ceeding a span in length. Stipules subulate, ad- 

 hering to the stem. Leaflets five to eight pair, smooth, 

 and often deeply emarginated above. Peduncles 

 producing mostly two flowers, sometimes three, which 

 are also unusually small, and of a pale blue color. 

 The divisions of the calix are subulated. The le- 

 gumes curving upwards, are at length black, and of a 

 thinnish substance, broad and flat beneath, present- 

 ing two carinated or angular margins, distinctly two 

 celled. The seeds flattish, and situated so near to 

 each other as to be mutually truncated at the extre- 

 mities.
