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 vv^ould 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.

A slender vine, the branches terete, 1 to 1.5 mm in diameter, 

 brownish when dry, the younger ones more or less pubescent, 

 the older ones glabrous. Leaves chartaceous, subolivaceous

 somewhat narrowed to the rounded, slightly cordate, and mi- 

 nutely peltate base, the apex acuminate, margins irregularly 

 undulate, the upper surface glabrous, the' lower surface with 

 rather numerous short, stiff stinging hairs from bulbous bases 

 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 

 oblong, 0.5 mm long, usually curved and persisting after the 

 flowers fall. Flowers sessile, 2 mm in diameter, 4-merous. 

 Sepals oblong, acuminate, 1 mm long. Stamens 4, rarely 3,
