Description

The Nabiac Casuarina is a straggling shrub of the sheoak family, 1 to 3 m in height. Like all sheoaks it has wiry foliage consisting of jointed branchlets rather than leaves. Leaves are reduced to ribs on the branchlets, projecting at the nodes as small teeth. In the Nabiac Casuarina the green, ridged branchlets grow to 20 cm long and at each joint there is a whorl of six tiny teeth. Male and female flowers are inconspicuous and occur on separate plants. Oblong woody cones to 3cm long contain the small winged seeds.

Distribution

The Nabiac Casuarina is restricted to the mid-north coast of NSW, from Nabiac to Forster and is very rare.
