Male flowers are arranged in spikes Шаблон:Cvt long, in whorls of seven to eight per centimetre (per 0.39 in.), the anthers about Шаблон:Cvt long. Female cones are on a peduncle Шаблон:Cvt long, the mature cones are Шаблон:Cvt long and Шаблон:Cvt in diameter, the winged seeds Шаблон:Cvt long.[1][2]

Taxonomy

This sheoak was first formally described in 1936 by Charles Gardner who gave it the name Casuarina tessellata in the Journal of the Royal Society of Western Australia from specimens collected in 1931.[3][4] It was reclassified in 1982 as Allocasuarina tessellata by Lawrie Johnson in the Journal of the Adelaide Botanic Gardens.[5] The specific epithet (tessellata) means "in a pattern of small squares".[6]

Distribution and habitat

Allocasuarina tessellata is only known from the Avon Wheatbelt and Yalgoo bioregions of inland Western Australia, where it grows in loamy and sandy soils near greenstone and dolerite boulders.

Conservation status

Allocasuarina tessellata is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.[2]
