Distribution and Ecology
Occurs in WA, NT, CYP, NEQ and southwards to Victoria. Altitudinal range from sea level to 1000 m. Grows in monsoon forest, well developed rain forest and wet sclerophyll forest. This species is favoured by disturbance. Also occurs in New Guinea.
Field evidence indicates that this species is a very important cause of sickness and death in livestock and its toxicity has been confirmed in feeding tests. Everist (1974).
Food plant for the larval stages of the Speckled Lineblue Butterfly. Common & Waterhouse (1981).
