In all the provinces, very common. Distrib. Throughout tropical 

 S.-E. Asia. 



Thougli very like the preceding this is quite easily distinguished hy its thicker 

 stems, larger and differently shaped leaflets, much longer pedicels and rather hroader 

 pods, the joints of which usually dehisce along the lower snture. 



The distribution in India and Malaya of these two species, is reversed. In India 

 this is quite a rare plant, D. trijlorum being common everywhere ; in Malaya, on 

 the other hand, D. triflorum is very rare while D. heterophi/llum is extremely common 

 and is apparently the representative of the other.
