 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 inermis 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. rukarn 

 has dioecious flowers. I refer to Flacourtia rukam the following Philippine

 surface glabrous, shining, the lower softly brown-pubescent, the 

 apex acuminate, base acute; lateral nerves about 12 on each 

 side of the midrib, somewhat curved-ascending, prominent; pe- 

 tioles stout, 5 mm long or less. Flowers yellowish, axillary, few,
