monoecious, the stems brown when dry, emitting numerous roots 
along the lower side, the internodes 3 to 5 cm long. Leaves 
alternate, when dry brownish-green, slightly shining, membran- 
aceous, subobliquely broadly ovate, 8 to 15 cm long, nearly as 
wide, shortly acuminate, margins repand, sometimes also spar- 
ingly denticulate, the base broadly truncate or subcordate-trun- 
cate, slightly inequilateral; basal nerves about 6; petioles up to 
8 cm long; stipules brown, persistent, ovate to oblong-ovate, 1.5 
to 2 cm long. Flowers pink and white, in the upper axils, fas- 
cicled, numerous male and few female ones in the same fascicle, 
the former short-pedicelled, the latter apparently long-pedicel- 
led, the fascicles subtended by several large, persistent, brown, 
bracts. Male flowers : Sepals 2, membranaceous, broadly elliptic- 
ovate, about 12 mm long, 10 mm wide. Petals none. Stamens 
about 30, on an elongated torus; anthers narrowly elliptic- 
oblong, obtuse, 2 mm long, their filaments shorter. Female 
flowers not seen. Capsules obovoid to turbinate, subequally 3- 
winged, about 3 cm long, including the wings about 2 cm wide, 
the apex rounded-truncate, the base acute, dehiscent near the 
wings, the placentae cleft, ovulate on all sides ; peduncles slender,

A very characteristic species well distinguished by its scandent habit, 
its fascicled, comparatively large flowers, and its unusually large capsules. 
It has no close allies among the Philippine species.

A slender, monoecious glabrous, branched, scandent plant, 
the stems creeping along the trunks of trees, when dry reddish 
or reddish-brown. Leaves small, ovate, chartaceous when dry,
