Description
Allocasuarina gymnanthera is a dioecious shrub or tree that typically grows to a height of 2–5 m (6 ft 7 in – 16 ft 5 in). Its branchlets are more or less erect, up to 200 mm (7.9 in) long, the leaves reduced to erect, scale-like teeth 0.4–0.7 mm (0.016–0.028 in) long, arranged in whorls of six to eight around the branchlets. The sections of branchlet between the leaf whorls (the "articles") are 5–12 mm (0.20–0.47 in) long and 0.5–1.0 mm (0.020–0.039 in) wide. Male flowers are arranged like a string of beads, in spikes 25–60 mm (0.98–2.36 in) long, with three to five whorls per centimetre (per 0.39 in.), the anthers 0.8–1.4 mm (0.031–0.055 in) long. Female cones are cylindrical, on a peduncle 3–8 mm (0.12–0.31 in) long, the mature cones 14–40 mm (0.55–1.57 in) long and 9–12 mm (0.35–0.47 in) in diameter, the samaras dark brown to black and 4.5–7.0 mm (0.18–0.28 in) long.[2][3][4]
