Description: (subsp. orientalis (Hallier f.) van Ooststr.): "Perennial, creeping, sprawling, or twining vine...;the stems with white latex and becoming woody; petioles 1.5-10 cm long; leaf blades entire, narrowly deltoid to broadly ovate, 4-12 (-16) cm long, truncate to cordate or hastate at base, usually long-acuminate; sepals broadly elliptic or oblong to orbicular, 5-10 mm long, subequal or the outer ones slightly the shorter; corolla hypocrateriform, 2-3 (-3.5) cm long, yellow (sometimes white or orange); fruit ovoid to conical, 10-12 mm long, the seeds dark brown, 5-6.5 mm long, densely pubescent" (Smith, 1991; pp. 48-49).
Habitat/ecology: In Fiji, "cultivated and also occasionally naturalized in thickets and on edges of forest from near sea level to about 400 m" (Smith, 1991; pp. 48-49). "Locally common near the airport on Tutuila" (Whistler, 1988; p. 15). In New Caledonia, "assez commun à l'état spontané aux alentours du village de Koné" (MacKee, 1994; p. 42). "Fort curieusement cette espèce n'a jamais été récoltée, avant 1958, en Nouvelle-Calédonie; il est pourtant absolument sûr qu'il ne s'agit pas d'une introduction récente. Se rencontre communément dans les terrains vagues, aux alentours des villages" (Heine, 1984; pp. 40, 42). Moist uplands in the Galápagos Islands (McMullen, 1999; p. 307).
Propagation: Seed
Native range: Pantropical; the Old World population is now generally referred to as subsp. orientalis (Smith, 1991; pp. 48-49).
