Casuarina, also known as she-oak, Australian pine [3] [4] [5] and native pine, [6] is a genus of flowering plants in the family Casuarinaceae, and is native to Australia, the Indian subcontinent, Southeast Asia, islands of the western Pacific Ocean, and eastern Africa.
Casuarina equisetifolia, commonly known as coastal she-oak, horsetail she-oak, [3] ironwood, [4] beach sheoak, beach casuarina, whistling tree [5] or Australian pine [6] is a species of flowering plant in the family Casuarinaceae and is native to Australia, New Guinea, Southeast Asia and India.
Casuarina cunninghamiana is a dioecious tree that typically grows to a height of 15–35 m (49–115 ft), has a DBH of 0.5–1.5 m (1 ft 8 in – 4 ft 11 in). Its bark is finely fissured, scaly and greyish brown.
Casuarina obesa is a dioecious shrub or small tree that typically grows to a height of 3–15 m (9.8–49.2 ft) and has corky, deeply fissured bark. The branchlets are drooping or spreading to erect, up to 300 mm (12 in) long, the leaves reduced to scale-like teeth 0.3–1 mm (0.012–0.039 in) long, arranged in whorls of 12 to 16 around the branchlets and erect on new shoots.

Casuarina glauca, commonly known as swamp she-oak, swamp buloke, swamp she-oak, marsh sheoak, grey she-oak, grey she-oak, [2] native pine, [3] or guman by the Gadigal people, [4] is a species of flowering plant that is endemic to eastern Australia.
The genera Allocasuarina was created out of a grouping of plants formerly placed in Casuarina, because of subtle but consistent differences – Casuarina species have 6 to 20 scale-like teeth in each whorl of leaves, their samaras are grey or yellowish-brown, and the bracteoles of the fruiting cones are thin, woody and extend well beyond the ...
At one time, all species were placed in the genus Casuarina. Lawrence Alexander Sidney Johnson separated out many of those species and renamed them into the new genera of Gymnostoma in 1980 and 1982, [3] [4] Allocasuarina in 1982, [4] and Ceuthostoma in 1988, with some additional formal descriptions of new species in each other genus.

Allocasuarina littoralis, commonly known as black she-oak, [3] is a species of flowering plant in the family Casuarinaceae and is endemic to eastern Australia. It is dioecious, or less commonly a monoecious tree or shrub, that has its leaves reduced to scales, usually in whorls of six to eight, the mature fruiting cones 10–30 mm (0.4–1 in) long containing winged seeds 4.0–10 mm (0.2–0. ...
