Information
Climber or trailer to 8 m.; stems hispid-hairy or densely shortly or shaggy-hairy with colourless hairs. Leaf-blade ovate-, broadly reniform-, suborbicular-, or pentagonal-cordate in outline, sparsely to densely short- to long-hairy above and especially on the nerves beneath, becoming hispid or scabrid especially above, sinuate-toothed, often sharply so, 51–180 mm. long, 70–260 mm. broad, palmately 5-lobed; lobes triangular, broadest below, or ovate or ovate-elliptic, narrowed below and then often themselves 3-lobulate, acute to obtuse and apiculate; petiole hispid-hairy, 18–130 mm. long. Probracts sessile, oblanceolate-spathulate, cucullate, up to 12–18 mm. long and 8 mm. broad. Male flowers solitary or 4–13 in an 80–360 mm. long bracteate raceme, sometimes a solitary flower and a raceme coaxillary; peduncle of raceme 30–210 mm. long; pedicels of racemose flowers 3–25 mm. long, of solitary flowers 39–250 mm. long; bracts broadly obovate to lanceolate, cucullate, inrolled at the margins, 8–31 mm. long, 5–22 mm. broad, pale greenish-yellow; flowers 40–80 mm. in diameter, sweet-scented, night-flowering; receptacle-tube sparsely hairy, cylindrical or obconic-cylindrical, often slightly bulbous at the base, 15–32 mm. long; lobes linear-lanceolate, 6–13 mm. long; petals white to pale yellow, obovate-apiculate, 19–48 mm. long, 14–40 mm. broad. Female flowers on 10–55 mm. long stalks; ovary densely white-hairy or woolly, pale green, ellipsoid, 15–26 mm. long, 10–14 mm. across; receptacle-tube obconic-cylindrical, 11–22 mm. long; lobes linear-lanceolate, 6–13 mm. long; petals 26–38 mm. long, 20–22 mm. broad. Fruit on an 18–68 mm. long stalk, elongated-ellipsoid to ovoid or almost spherical, 42–141 mm. long, 29–50 mm. across, bright red and sparsely setose or ± lanate. Seeds elliptic in outline, smooth, lenticular, blackish, 6–10 × 3–5 × 1–1.5 mm. Fig. 11/1–7.

Notes
Plants from drier areas in the range tend to have the leaf-lobes narrowed towards the base, while those from rain-forest areas have rather uniform leaves with broadly triangular lobes; these differences have been used for specific distinction in the past, but although undoubtedly genetic seem to be of varietal order. However, some degree of heterophylly has been d in the material examined, and it seems that leaf-shape is not a reliable character for the establishment of taxonomic units. The shape and hairiness of the mature fruit and seed-size may prove of more value in defining variants, if indeed discontinuity of variation exists, but more material of these organs needs to be examined before definite conclusions can be drawn. Further collecting and field observations are very desirable, but in the meantime it seems better to treat all the variants within one species unit, rather than to try to define variants on leaf-shape alone.
