Endemic to Queensland, occurs in NEQ and northern part of CEQ, from Murray Falls near Cardwell to Mt Elliot, south of Townsville. Altitudinal range from 50-600 m. Usually grows in open forest but also occurs on rain forest margins and in permanent openings in rain forest caused by factors such as rock slabs and outcrops particularly on granite substrates.
