Allocasuarina dielsiana

Allocasuarina dielsiana, commonly known as the Northern sheoak, is a tree of the genus Allocasuarina native to the Mid West and Goldfields-Esperance regions of Western Australia..

The dioecious tree typically grows to a height of 4 to 9 metres (13 to 30 ft). It is found in stony red soils over granite in hilly country.

The species was first described as Casuarina dielsiana by the botanist Charles Austin Gardner in 1936 in the Journal of the Royal Society of Western Australia. It was subsequently reclassified into the Allocasuarina genera by Lawrence Alexander Sidney Johnson in 1982 in a revision of the sheoaks published in the Journal of the Adelaide Botanic Gardens.
