The genus is new to the Philippines. While the specimen 
cited above differs in some details from Smith’s species, as 
described, I can detect no differences, in the absence of named 
material for purposes of comparison, that would warrant me 
in distinguishing the Philippine form as specifically or varietally 
distinct. According to Hooker the species extends from the 
Himalayan region to Java; it extends at least as far to the 
southeast as Amboina, as it was figured by Rumphius, Herb.

1 mm long or less ; petioles 5 to 10 mm long, sparingly hirsute, 
ultimately glabrous; lateral nerves 6 or 7 on each side of the 
midrib, distinct, spreading, anastomosing, the reticulations lax. 
Staminate inflorescences spicate, slender, axillary, solitary or 
fascicled, puberulent, 5 to 7 cm long, the bracteoles narrowly
