Vine or clambering shrub; young branchlets green, compressed, sparsely or moderately (but unevenly) pilose in strips down opposite sides with slender and unbranched trichomes 0.2-1 mm long; older branches terete, glabrous, developing brown or grayish-brown bark. Leaves with petioles 1.5-7(-15) mm long which are pilose (but not densely so) with trichomes to 1 mm long; blades ovate to ovate-lanceolate or elliptic, apically acuminate or sometimes acute, basally acute to rounded or cordate, 4-12 cm long, 1.5-5 cm broad, membranous to subcoriaceous, very sparsely pilose along the principal veins (above and below) and along the margins with simple trichomes 0.2-1 mm long, less frequently entirely glabrous, 3(5)-plinerved, the primary nerves raised below and somewhat impressed above, the reticulation on both surfaces ranging from apparent to prominulous (rarely obscure above). Infloresences terminal, cymose. Flowers with pedicels obsolete to ca 3.5 mm long (in each 3-flowered dichasial component of the terminal cyme the central pedicel is manifestly shorter than the 2 lateral pedicels, the central flower thus often appearing subsessile); calyx-lobes slender-lanceolate to slightly ovate-lanceolate, 2.5-4 mm long, marginally ciliate but otherwise glabrous, the tube absent to ca 0.5 mm long; corolla salverform, white to green or yellow, ex-ternally minutely papillose (not with well defined trichomes), the tube 13-24 mm long, 1-2.5 mm broad, conspicuously pilose internally with trichomes to 1 mm long except near the throat and base, the lobes linear-lanceolate, 3-4.5 mm long, densely papillose internally; anthers 0.7-1 mm long, glabrous, exserted from the corolla-tube by 1.5-3 mm on filaments adnate to the corolla-tube to the throat but extending beyond; ovary 1-1.5 mm long, 2-locular, passing almost imperceptibly into the long tapering style, the style exserted by 2-4 mm, terminated by a small capitate and unlobed stigma. Fruit globose, 2.5-8 cm in diameter, frequently turn-ing orange, the pulp yellowish or light orange, several to oo-seeded.
