Allocasuarina grevilleoides

Allocasuarina campestris is a spreading dioecious shrub that typically grows to a height of 15–30 cm (5.9–11.8 in). Its branchlets are more or less erect and sharply pointed, 10–30 mm (0.39–1.18 in) long, the leaves reduced to erect, overlapping, scale-like teeth 0.3–0.6 mm (0.012–0.024 in) long, arranged in whorls of four around the branchlets, but withering as they age. The sections of branchlet between the leaf whorls (the "articles") are 10–24 mm (0.39–0.94 in) long and 0.5–0.8 mm (0.020–0.031 in) wide. Male flowers are arranged in dense spikes 2–5 mm (0.079–0.197 in) long, the anthers 0.6–0.7 mm (0.024–0.028 in) long. Female cones are oval and sessile, the mature cones 9–14 mm (0.35–0.55 in) long and 6–9 mm (0.24–0.35 in) in diameter, the samaras dark brown and 5.5–7.0 mm (0.22–0.28 in) long.

Allocasuarina grevilleoides is restricted to the Jurien Bay-Mogumber area in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia.
