Description:  "Tuberous vine, tubers usually globose or pear-shaped, sometimes lobed, some edible (in cultivated races), others (in wild races) causing nausea or fatal; flesh yellowish; stems generally bearing bulbils, twining to the left (clockwise); leaves broadly cordate, 20-30 cm long, 20-30 cm wide, 5-nerved, lower surface duller green than upper,  short to long petiolate, petioles sometimes slightly winged, but stems not so; male flowers on pendent inflorescence, from bracteate (rarely leafy) stems, up to 50 (even 100) cm long; whitish or pinkish; female flowers on pendent axillary inflorescences; capsules winged, wings to 20 x 9 mm, rounded at both ends"  (Stone, 1970; pp. 127-128).

Habitat/ecology:  "Probably an intentional aboriginal introduction into Polynesia. It is common to locally abundant in plantations and on roadsides, as well as being naturalized in secondary and sometimes in primary forests" (Whistler, 1983; p. 80).

In Hawai‘i, "a Polynesian introduction, naturalized primarily in mesic areas, especially shaded mesic valleys and disturbed mesic forest, 5-670 m" (Wagner et al., 1999; p. 1437).  In Fiji, "cultivated and also naturalized, occurring in various types of forest from near sea level to 900 m" (Smith, 1979; pp. 168-169).  "Common in plantations and secondary forest" (Whistler, 1988; p. 45).

Propagation:  Seed

Native range:  East Africa to Polynesia (Stone, 1970; pp. 127-128), probably an early introduction to Pacific islands.
