Description

Allocasuarina distyla is a dioecious shrub that typically grows to a height of Шаблон:Cvt and usually has smooth bark. Its branchlets are more or less erect, up to Шаблон:Cvt long, the leaves reduced to erect, scale-like teeth Шаблон:Cvt long, arranged in whorls of six to eight around the branchlets. The sections of branchlet between the leaf whorls (the "articles") are Шаблон:Cvt long and Шаблон:Cvt wide. Male flowers are arranged in spikes Шаблон:Cvt long, in whorls of 4.5 to 6.5 per centimetre (per 0.39 in.), the anthers Шаблон:Cvt long. Female cones are cylindrical, on a peduncle Шаблон:Cvt long or sometimes longer. Mature cones are Шаблон:Cvt long and Шаблон:Cvt in diameter, the samaras dark brown to black and Шаблон:Cvt long.[1][2][3]

Hybrids with A. littoralis are common between Broken Bay and Port Hacking.[1][2]

Taxonomy

This species was first described in 1802 by Étienne Pierre Ventenat who gave it the name Casuarina distyla in his book, Description des Plantes Nouvelles et peu connues, cultivees dans le Jardin de J.M. Cels.[4][5] It was reclassified in 1982 into the genus Allocasuarina as A. distyla by Lawrie Johnson in the Journal of the Adelaide Botanic Gardens.[6][7] The specific epithet, (distyla) means "distylous".[8]

Distribution and habitat

Scrub she-oak grows in tall heath on sandstone ridges on the coast of New South Wales between Port Stephens and Eden, and inland as far as Wollemi National Park and Cooma.[1][3]
