Habitat/ecology:  In Hawai‘i, "occasionally cultivated and sparingly naturalized" (Wagner et al., 1999; p. 1034).  In Fiji, "occurring at elevations of sea level to about 400 m as a weed along roadsides, in plantations, on damp ground in shady places near houses, and occasionally along forest trails" (Smith, 1981; p. 89).  In Samoa, "occasional in croplands and waste places" (Whistler, 1988; p. 33). In New Guinea, "a weed of gardens, nurseries and plantations, in damp shady conditions; only troublesome where large weeds have been eliminated, leaving bare ground. From sea level to 700 m" (Henty & Pritchard, 1975; p. 133).
