Casuarinaceae is a family of dicotyledonousflowering plants placed in the order Fagales, consisting of 3 or 4 genera and approximately 70 species of trees and shrubs native to the Old World tropics (Indo-Malaysia), Australia, and the Pacific islands. At one time, all of the species were placed in the Genus Casuarina, but these are now split among Allocasuarina, Casuarina, and Gymnostoma. Members of this family are characterized by drooping equisetoid (meaning to look like Equisetum) twigs, are evergreen, and monoecious or dioecious. The roots have nitrogen-fixing nodules.
Casuarina equisetifolia L. is a widespread seashore tree known as Common Ironwood, Beefwood, Bull-oak, and Whistling-pine and is often planted as a windbreak. The wood of this tree is used for shingles, fencing, and is said to make excellent, hot burning, firewood.
Casuarinaequisetifolia is a deciduous tree with a pine-like appearance.
Casuarina species are reported to tolerate annual precipitation of 6.4 to 43 dm, annual temperatures of 22.1 to 26.9°C, and pH of 5.0 to 7.7 (Duke 1983).
equisetifolia was introduced to Florida in the late 1800's and planted widely for the purposes of ditch and canal stabilization, shade, and lumber (Swearingen 1997).
