Allocasuarina hystricosa is a small, dioecious sheoak shrub from south-western Western Australia, growing up to about 3 m. Grow it in full sun in free-draining soil, as it suits dry mallee and heath conditions.
Allocasuarina hystricosa is a species of flowering plant in the family Casuarinaceae and is endemic to the south of Western Australia. It is a dioecious shrub with more or less erect branchlets, the leaves reduced to scales in whorls of ten to twelve, the fruiting cones 13–30 mm (0.51–1.18 in) long containing winged seeds (samaras) 4.5–9 mm (0.18–0.35 in) long.
The species grows in mallee shrubland or heath, in association with Acacia ophiolithica, Hakea verrucosa and Allocasuarina campestris. It also forms small dense stands, sometimes with Melaleuca pauperiflora and Gahnia lanigera. It occurs on plains, slopes and hilltops in small populations between Bendalup Hill and the Eyre Range north-east of Ravensthorpe in the Esperance Plains bioregion of southern Western Australia.
