Description

Allocasuarina nana is a spreading, dioecious or rarely monoecious shrub that typically grows to a height of Шаблон:Cvt. 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 four to six around the branchlets. The sections of branchlet between the leaf whorls are Шаблон:Cvt long and Шаблон:Cvt wide. Male flowers are arranged in dense spikes Шаблон:Cvt long, with 16 to 20 whorls per centimetre (per 0.39 in.), the anthers Шаблон:Cvt long. Female cones are sessile or on a peduncle up to Шаблон:Cvt long, the mature cones cylindrical to barrel-shaped, Шаблон:Cvt long and Шаблон:Cvt in diameter, the winged seeds Шаблон:Cvt long.[1][2][3][4]

Taxonomy

This she-oak was first described in 1826 by Kurt Polycarp Joachim Sprengel who gave it the name Casuarina nana in Systema Vegetabilium, from an unpublished description by Franz Sieber.[5][6] In 1989 by Lawrie Johnson transferred the species to the genus Allocasuarina as A. nana in the Journal of the Adelaide Botanic Gardens.[7][8] The specific epithet, (nana) means "dwarf".[9]

Distribution and habitat

Allocasuarina nana grows in heath over sandstone in exposed places on the coast and tablelands of New South Wales south from Cowan and Glen Davis to the far north east of Victoria.[1][2][3]
