This sheoak was first formally described in 1845 by Friedrich Anton Wilhelm Miquel who gave it the name Casuarina trichodon in Lehmann's Plantae Preissianae. In 1982, Lawrie Johnson transferred the species to Allocasuarina as A. trichodon in the Journal of the Adelaide Botanic Gardens. The specific epithet (trichodon) means "hair-like tooth", referring to the leaves. ==Distribution and habitat==

Allocasuarina trichodon grows in tall heath, often in rocky skeletal soils on granitic hillsides from Albany to east of Esperance and in the Stirling Range National Park in the Esperance Plains, Jarrah Forest and Warren bioregions of southern Western Australia. ==References==
