disposed in racemes (f. 43. g. f. 44. c.). Legumes compressed 

 (f. 43. 1. f. 44. g.). 



CXL. DI'PHACA (from etc, dis, twice, and (JXIKTI, phake, a 

 lentil or pea ; in reference to the pods being composed of 2 1 - 

 seeded joints). Lour. coch. p. 454. D. C. prod. 2. p. 313. 



LIN. SYST. Diadelphia, Decandria. Calyx 5-cleft, perma-

 joined into 2 5-anthered bundles. Carpels 2, 1 -styled. Le- 

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

 seeded. This genus is allied to Dalbergia and JEschinomene, 

 in the stamens being equally diadelphous, but the fruit is arti- 

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

 the same tribe.
