"Tree 10-20 m high, frequently producing suckers. Bark finely fissured or scaly, grey-brown."  (Flora of Australia)

All Casuarina spp. are dioecious except C. equisetifolia.

Within the Family Casuarinaceae, leaves are modified down to "teeth" observable as whorls. The whorls are located between portions of the branchlets, the portions being referred to as "articles". Casuarina cristata has 8-12 teeth at the junctions of the articles. Photographs below show these morphological features.

Usually found on heavy soils.

Seed collection in scale from this species requires lopping of branches and handling of that material on to drying tarps. Field drying is far more efficient if at all possible and usually results in less cleaning later. Branchlets which are reduced down to articles in the pre-cleaning material can be difficult to seperate without appropriate machinery.
