Allocasuarina grampiana is a dioecious shrub that typically grows to a height of Шаблон:Cvt and has smooth bark. Its branchlets are more or less erect, up to Шаблон:Cvt long, the leaves reduced to erect to slightly spreading, scale-like teeth Шаблон:Cvt long, arranged in whorls of six or seven around the branchlets. The sections of branchlet between the leaf whorls (the "articles") are Шаблон:Cvt long, Шаблон:Cvt wide and have a waxy covering. Male flowers are arranged in spikes Шаблон:Cvt long, the anthersШаблон:Cvt long. Female cones are cylindrical, on a peduncleШаблон:Cvt long. Mature cones are Шаблон:Cvt long and Шаблон:Cvt in diameter, the samaras Шаблон:Cvt long.[1][2]
