Distribution and Ecology
Occurs in NEQ and southwards to coastal central Queensland. Altitudinal range from near sea level to 900 m. Grows along roads and in clearings in rain forest. Also occurs in Malesia and the Pacific islands.
In upper Naitasiri Province, Fiji, the name viavia tobacco has been noted, and an extract from the leaves is used for sore eyes (St John 19287). A.C. Smith (991).
