Distribution and Ecology
Endemic to Queensland, occurs in NEQ and southwards as far as south-eastern Queensland but not in coastal central Queensland. Altitudinal range from 450-850 m. Grows as an understory tree in drier, more seasonal rain forest often associated with Kauri Pine (Agathis robusta).
