About

Allocasuarina luehmannii, commonly known as buloke or bull-oak, is a species of flowering plant in the family Casuarinaceae and is endemic to south-eastern continental Australia. It is a dioecious tree, that has its leaves reduced to scales in whorls of ten to fourteen, and the mature fruiting cones are 5–12 mm (0.2–0.5 in) long containing winged seeds (samaras) 4–5 mm (0.16–0.20 in) long.

Where it grows

Allocasuarina luehmannii usually grows in scattered places in woodland from Mareeba and south through central Queensland, New South Wales and the Australian Capital Territory to north-western Victoria and nearby areas of South Australia. It rarely occurs near the coast, except in the Hunter Valley and near Rockhampton.
