Description.
Perennial climber. Stems up to 5 m, glabrous. Petiole 0.9-4.5 cm, glabrous. Leaves 7-12 cm
x
2.5-11 cm, 5-angularly subcordate, subhastate, rarely 3-lobate, auriculate. Lobes elliptical. Margin suspiciously dentate, whitish in living state, blackening when dried. Apex acute with final tooth. Upper leaf surface pale to white pustulate. Lower leaf surface glabrous, nerves often white-speckled. Probracts <1 mm, often missing. Tendrils simple, rarely bifid. Male flowers ebracteate, in glabrous racemes, occasionally accompanied a solitary flower. Common peduncle 0.7-1.5 cm, pedicel of flowers in raceme 2.5-8 mm, pedicel of solitary flower 5-10 mm. Perianth tube glabrous, calyx lobes 2-3 mm long, (0.75-)1.2-1.8 mm broad at base, erect. Corolla 0.8-1.5 cm long, yellow to (pale) orange, sometimes with greenish nerves. Corolla lobes up to 2 mm long. Filament column and anther head not seen, pollen sacs yellow to orange. Female flower solitary. Petiole 1.5-2.2 cm, glabrous. Hypanthium glabrous, calyx lobes and corolla not seen, but likely as in male plants. Ovary glabrous. Style and stigmas not seen. Fruit up to 20 cm long, c. 1 cm in diam., long cylindrical, unripe waxy green, ripe unknown. Seed size and shape unknown, face flat.
Phenology.
Flowering time: May-December.
Distribution.
Fig.

. Tropical West Africa: SW Ivory Coast, S Ghana, SE Benin, SW Nigeria. Elevation sea level to 460 m. Soil preference not known. In primary or secondary forests, in disturbed places (roadsides, near rivers).
Remarks
.
The broad calyx lobes are, apart from the long cylindrical fruit, the best character for identifying this species. An urceolate corolla (
Jongkind 2004
) also occurs in
Coccinia barteri
.
A single collection (
H.J. Beentje 602
from M) mentions a lilac corolla color, which would be unique in
Coccinia
. Although this might be possible, since there are also pinkish flowers reported in
Coccinia adoensis
, the fact that the WAG duplicate with the same collection number is a
Ruthalicia
makes it more likely that the observation is due to a mixed collection, eventually from a
Convolvulaceae
.
