Distribution and Ecology
Occurs in NEQ, south-eastern Queensland and southwards to eastern Victoria. Altitudinal range in NEQ from 850-1000 m. Usually grows in drier wet sclerophyll forest but in NEQ it may occur on the margin of mountain rain forest.
This species may have medicinal properties. (http://farrer.riv.csu.edu.au/ASGAP/APOL10/jun98-6 .html)
