Description

Dwarf Heath Casuarina is a member of the She-oak family. It is a straggly shrub to 2 m high growing from a tuber. Like all She-oaks 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 Dwarf Heath Casuarina the foliage is blue-green, the branchlets are up to 12 cm long and the leaf teeth may overlap. Male and female flowers are inconspicuous, and are both monoecious, occurring on separate plants, and dioecious,  found on the same plant. The cones are very irregular, 8 to 11 mm long, held on narrow stalks to 7 mm.

Distribution

Dwarf Heath Casuarina is found only in NSW from the Nabiac area, north-west of Forster, and at Crowdy Bay.

Habitat and ecology

  • Dwarf Heath Casuarina grows mainly in tall heath on sand, but can also occur on clay soils and sandstone.
