In vegetative characters this species is exceedingly variable, the leaflets varying 

 from one to seven, and on some specimens the same branches bearing 1-3- and 

 5-foliolate leaves. The flower and fruit characters appear to be rather constant. 



This species has been reported from the Feejee Islands by A. Gray,' but possibly 

 on an erroneous identification, or on a wrongly localized plant. Otherwise not 

 reported from outside the Philippines.
