The names, Belah and Black Oak, have also been applied to
Casuarina cristata, with some confusion over the scientific names of the two species. Casuarina cristata is a tree of central to eastern New South Wales and south-east Queensland. Differs from Swamp Sheoak (Casuarina obesa) in that its reduced leaves (teeth) are generally less than 12/whorl and spreading or recurved and its branchlets are more or less covered in hairs. Produces a very dense wood suitable for fencing, fuel, construction and wood-turning.
