Evergreen robust vine or climber, with large subterranean tubers; stems smooth (up to 30 m high) emitting a milky latex when damaged.
Leaves: Green, hairless above, purple veins below with scattered hairs, simple, almost round but abruptly tapering to a sharp point (7.5–30 cm long and 7–20 cm wide), held alternately on stems, leaf stalk attached to the underside of the leaf blade instead of at its base or margin (3–24 cm long).

Fruits: Capsule (dry fruit that opens at maturity) (15 mm long), splitting into many valves; seeds brown.
 
ORIGIN
Uncertain but assumed to be native to Pemba, Madagascar, Mauritius, Reunion, Seychelles, Malaysia, Indonesia, the Philippines, northern Australia and eastwards into Polynesia to the Society Islands. Different biotype may be invasive in Bukit Barisan Selatan National Park in Indonesia.
 
REASON FOR INTRODUCTION
Medicine, land restoration and ornament.
 
INVADES
Roadsides, disturbed land, wasteland, urban open space, fallow land, plantations, forest edges/gaps and woodland edges/gaps.
 
IMPACTS
Smothers native vegetation to the detriment of plant and animal life. In Vanuatu, it is considered to be one of the most important weeds of plantation forestry and is one of two major specie sthreatening natural regeneration in logged or disturbed areas (Bakeo and Qarani, 2005). In Indonesia, it also inhibits and/or prevents the movement of threatened and rare species such as elephants, rhinos and tigers.
