Description
|
Shrub or woody vine; branchlets distally hirsutulous with ascending or up- wardly curving trichomes to ca 0.2 mm long, less frequently glabrate, the older branches glabrous, terete or subtetragonal. Leaves with petioles 3-10 mm long; blades ovate or ovate-lanceolate to elliptic-lanceolate or elliptic-obovate, apically acuminate or subacuminate, basally cuneate to rounded, 4-20 cm long, 2-7.5 cm broad, essentially glabrous (occasionally sparsely and minutely puberulent below on the primary nerves and above toward the base of the medvein), grayish-green and sublustrous on drying, 3(5) -plinerved, the primary nerves conspicuously raised below, the reticulation intricate and prominulous to prominent on both surfaces. Inflorescences axillary, thyrsoid, rather elongate, the main axis bearing several pairs of opposite floriferous branchlets. Flowers with pedicels virtually obsolete to 4.5 mm long and hirsutulous to essentially glabrous; calyx-lobes ovate to deltoid- or rhombic-ovate, apically acute or subacuminate, to 1.5 mm long, ex- ternally glabrous to papillose or minutely hirsutulous, marginally rather con- spicuously ciliate; corolla white, saverform, externally papillose but otherwise glabrous, the tube 1.5-4 mm long, internally pilose, the lobes 2-5.5 mm long, linear-lanceolate, often recurved, lanate on the whole inner surface; anthers 1.5-2 mm long, glabrous, linear or narrowly trullate, basally rounded, exserted by 1.5-4.5 mm, the filaments becoming free at the throat of the corolla; ovary subglobose, ca 1 mm long, passing manifestly into the style, the style glabrous, exserted by 2-5 mm from the corolla-throat, the stigma small and barely aparent (only slightly enlarged), single or 2-parted. Fruit ovoid to subglobose, ca 2 cm long, 1.5-2 cm broad, yellowish-green, with 1 or 2 large black seeds.
