Description

Habit:

Vines. Stems decumbent or twining, mostly cylindrical, glabrous or less often appressed-tomentose.

Leaves:

Leaves with petioles mostly 1cm long, the blades narrowly lanceolate to elliptical, 4-8 cm long, (0.5-)1-2 cm wide, basally obtuse to acute, apically obtuse to acuminate, mucronate, glabrous or with scattered appressed indumentm above and below, especially along the veins.

Inflorescences:

Inflorescences usually solitary in the leaf axils, at times cymose, with 2-3 flowers.

Flowers:

Flowers on peduncles 3-8 long, mostly glabrous, the bracts elliptic, 2-3 mm long, caducous or persistent, the pedicels 4-5 mm long, mostly glabrous. Sepals unequal, the outer two larger than inner, 12-20 mm long, 9-12 mm wide, the inner shorter and narrower, decurrent on the pedicels, basally cordate to obtuse, apically acuminate to acute, pubescent or glabrous; corollas campanulate, white, 25-30 mm long, about as wide, rarely smaller, the interplicae sericeous; stamens 13-15 mm long, the filaments glandular pubescent basally, the anthers 3-4 mm long, white, ovoid; ovary ovoid, attenuate to the style, glabrous, the style 15-16 mm long, the disc white or inconspicuous, the stigmas ± globose, white.

Fruits:

Fruits capsular, ovoid, apiculate, glabrous, 15-20 mm long, surrounded basally by the somewhat acrescent sepals, 2-locular, 2-4-valvate

Seeds:

Seeds 3-4, ovoid to obovoid, 5-6mm long, dark brown to almost black, glabrous or with hilar tuft and short trichomes along margins. 2n = 60 (Miège 1960, Lewis et al. 1967).
