Description:  "Stems climbing, slender and often reddish.  Leaves subsessile or with petiole to 1-(2) cm long, commonly with small irregular tubers in their axils.  Lamina 2-11-(13) x 1.75-10-(11) cm, broadly ovate, often involute, scarcely succulent to succulent according to degree of exposure, shining; base subcordate or cordate; apex obtuse.  Racemes simple or 2-4-branched, pendent, to ca 18 cm long excluding common peduncle, with numerous small, white, fragrant flowers.  Pedicels 2-3 mm long; bracts 1.5-1.8 mm long, lanceolate-subulate.  Lower bracteoles 0.5-1 mm long, cupulate; upper bracteoles ca 2-2.5 mm long, suborbicular.  Tepals 2-3 mm long, elliptic-oblong to broadly elliptic.  Filaments narrow-triangular, widely divergent, bending outwards near base.  Style 1, shorter than stamens; branches 1/2-3/4 length of fused part; stigmas clavate"  (Webb et al., 1988; pp 352-353).

Habitat/ecology:  "...in Queensland and New South Wales [Australia], it is a weed of riparian vegetation, the edges of rainforest, tall open forest and damp sclerophyll forests". (Csurhes & Edwards, 1998; p. 93).  In New Zealand, "Waste land, especially scrub-covered areas such as coastal gullies. Where it has become naturalised its smothering habit makes it a nuisance and this is even more true on tropical Pacific Islands to the north [of New Zealand]" (Webb et al., 1988; pp 352-353).  In Hawai‘i, "commonly cultivated and often escaping, now sparingly naturalized"  (Wagner et al., 1999; p. 381, 1864). In New Caledonia, "aujourd'hui assez rare en terrains vagues et fourrés secondaires" (MacKee, 1994; p. 21).

Propagation:  Rhizomes and stem tubers. Axillary tubers break off and are transported by water. Cultivated as an ornamental and thus spread by humans.

Native range:  Tropical South America.

Comments:  A serious problem on the Kermadec Islands (Raoul). A weed species in Australia and New Zealand.

Control: 

Physical:  "Manual removal must include the removal of all tubers".

Chemical:  "Effective chemical control is done by applying glyphosate or fluoroxypyr.  Repeated applications are necessary to achieve long-term control"  (Weber, 2003; p. 48).
