Allocasuarina thuyoides, commonly known as the horned sheoak, is a shrub of the genus Allocasuarina native to a large area in the Mid West, Wheatbelt, South West and Goldfields-Esperance regions of Western Australia.[3]

The monoecious or dioecious shrub typically grows to a height of 0.3 to 2 metres (1.0 to 6.6 ft). It flowers from January to December and produces cones with long spines. A. thuyoides is found heathland, sandplains and foothills and grows in clay or sandy lateritic soils.
Taxonomy

First described as Casuarina thuyoides in 1845 by Friedrich Anton Wilhelm Miquel,[4][5] it was assigned to the new genus, Allocasuarina, by L.A.S.Johnson, in 1982.[1][2]
