Allocasuarina mackliniana is a species of flowering plant in the family Casuarinaceae and is endemic to southern continental Australia. It is a dioecious, rarely a monoecious shrub that has more or less erect branchlets up to 200 mm (7.9 in) long, the leaves reduced to scales in whorls of seven to ten, the fruiting cones 12–22 mm (0.47–0.87 in) long containing winged seeds (samaras) 5–8 mm (0.20–0.31 in) long.
Allocasuarina mackliniana is a dioecious, or rarely a monoecious shrub that typically grows to a height of 0.5–3 m (1 ft 8 in – 9 ft 10 in) and has smooth bark. Its branchlets are more or less erect, up to 200 mm (7.9 in) long, the leaves reduced to spreading or curved, scale-like teeth 0.7–2 mm (0.028–0.079 in) long, arranged in whorls of seven to ten around the branchlets. The sections of branchlet between the leaf whorls (the "articles") are 7–17 mm (0.28–0.67 in) long, 0.8–1.4 mm (0.031–0.055 in) wide. Male flowers are arranged in thick, dense spikes 10–40 mm (0.39–1.57 in) long, the anthers 0.8–1.5 mm (0.031–0.059 in) long. Female cones are cylindrical and sessile or on a peduncle up to 3 mm (0.12 in) long. Mature cones are cylindrical, mostly 12–22 mm (0.47–0.87 in) long and 8–14 mm (0.31–0.55 in) in diameter, the samaras dark reddish-brown to black, and 5–8 mm (0.20–0.31 in) long.[2][3]
