This species is widely distributed in the Philippines, and is somewhat 
variable in its vegetative characters. In general the leaves of the Philip- 
pine form average considerably larger than in our rather comprehensive 
set of Malayan forms, but there appears to be no specific difference. The 
species is very similar in vegetative characters to Flacourtia inemnis Roxb., 
with which the Philippine specimens have been confused. As indicated 
in the original description, as later noted by King, and as shown in our 
Malayan specimens, Flacourtia inermis has perfect flowers, while F. rukam 
has dioecious flowers. I refer to Flacourtia rukam the following Philippine
