Description

Allocasuarina tortiramula is a dioecious shrub that typically grows to a height of up to about Шаблон:Cvt. Its branchlets are spreading and twisted, up to about Шаблон:Cvt long, the leaves reduced to scale-like teeth arranged in whorls of seven, 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, the anthers Шаблон:Cvt long. Female cones are sessile, mature cones Шаблон:Cvt long and about Шаблон:Cvt in diameter, the winged seeds brown and Шаблон:Cvt long.[1][2]

Taxonomy

Allocasuarina tortiramula was first formally described in 1989 by Eleanor Marion Bennett in the Flora of Australia from specimens collected near Lake King in 1987.[3][4] The specific epithet (tortiramula) means "twisted branchlet".[4]

Distribution and habitat

Twisted sheoak is only known from two populations growing in and near a nature reserve to the west of Lake King, where it grows in dense, tall heath.[1][2]

Conservation status

Allocasuarina tortiramula is listed as "threatened" in Western Australia.[1]
