Allocasuarina paludosa, commonly known as swamp she-oak[1] or scrub sheoak,[2] is a species of flowering plant in the family Casuarinaceae and is endemic to south-eastern continental Australia. It is a monoecious or dioecious shrub that has branchlets up to Шаблон:Cvt long, the leaves reduced to scales in whorls of six to eight, the fruiting cones Шаблон:Cvt long containing winged seeds Шаблон:Cvt long.

Description

Allocasuarina paludosa is a spreading, monoecious or dioecious 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 or spreading, scale-like teeth Шаблон:Cvt long, arranged in whorls of six to eight around the branchlets. The sections of branchlet between the leaf whorls are Шаблон:Cvt long and Шаблон:Cvt wide. Male flowers are arranged in spikes Шаблон:Cvt long, with 7 to 9 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 oval, Шаблон:Cvt long and Шаблон:Cvt in diameter, the winged seeds dark brown to black and Шаблон:Cvt long.[1][2][3][4]

Taxonomy

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in 1826 by Kurt Polycarp Joachim Sprengel who gave it the name Casuarina paludosa in Systema Vegetabilium, from an unpublished description by Franz Sieber.[5][6] In 1989 Lawrie Johnson transferred the species to the genus Allocasuarina as A. paludosa in the Journal of the Adelaide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

Distribution and habitat

Allocasuarina paludosa grows in heath and in poorly drained soils near swamps at the edge of woodland on the coast and nearby tablelands of New South Wales south from Broken Bay, through southern Victoria to the far south-east of South Australia.[1][2][3][4]
