 Corolla papilionaceous. Keel of 2 distinct petals. Stamens 

 joined into 2 5-anthered bundles. Carpel ■> 2, 1 -styled. Le- 

 gume compressed, slraiglit, articulated ; joints striated, 1- 

 fieeded. This genus is allied to Dafbergia and jEscIiinomefie, 

 in the stamens be'njr equally dladelphous, but the fruit is arti- 

 culated as in Hedysarum, and the plant is therefore placed in 

 the same tribe.
