Bat for the more slender and glabrous stems there is no character to separate 

 VAR. gracilis from P. calcaratus which is otherwise a safi&ciently variable species. 

 Except that it is described as having subtorulose pods even when old, the writer 

 would have no hesitation in referring P. luteus Bl. to var. gracilis. As a matter 

 of fact the pods of all the varieties of P. calcaratus are subtorulose when young, 

 and in B;Oxburgh's P. toi'osus, which is referable to P. calcaratus, they continue so ; 

 but, not having seen specimens, the writer does not feel justified in formally 

 reducing Blume's plant, and would leave the matter to be settled by the botanists 

 of the Dutch Indies.
