Allocasuarina torulosa, commonly known as forest oak, rose sheoak,[1] river oak or Baker's oak,[2] is a species of flowering plant in the family Casuarinaceae and is endemic to eastern Australia. It is a slender, usually dioecious tree that has drooping branchlets up to Шаблон:Cvt long, the leaves reduced to scales in whorls of four or five, and the fruiting cones Шаблон:Cvt long containing winged seeds Шаблон:Cvt long.
Description
Allocasuarina torulosa is slender, usually dioecious tree that typically grows to a height of Шаблон:Cvt. Its branchlets are drooping, up to Шаблон:Cvt long, the leaves reduced to erect, scale-like teeth Шаблон:Cvt long, arranged in whorls of four or five around the branchlets. The sections of branchlet between the leaf whorls are Шаблон:Cvt long, Шаблон:Cvt wide and more or less square in cross-section when young. Male flowers are arranged in spikes Шаблон:Cvt long, with 7 to 12 whorls per centimetre (per 0.39 in.), the anthers Шаблон:Cvt long. Female cones are on a peduncle Шаблон:Cvt long, and mature cones warty, shortly cylindrical to barrel-shaped, Шаблон:Cvt long and Шаблон:Cvt in diameter, containing brown, winged seeds Шаблон:Cvt long.[1][2][3]
Taxonomy
Forest oak was first formally described in 1789 by William Aiton, who gave it the name Casuarina torulosa in Hortus Kewensis from specimens collected by Joseph Banks.[4][5] In 1982, Lawrie Johnson transferred the species to Allocasuarina as A. torulosa in the Journal of the Adelaide Botanic Gardens.[6][7] Since it was the first species of the genus Allocasuarina to be named by Johnson, it is the type species of that genus.[8]
Distribution and habitat
Allocasuarina torulosa grows in open forest and on rainforest fringes in moister, more nutrient rich soils than A. littoralis at altitudes from Шаблон:Cvt. It is widespread in north-eastern and central-eastern Queensland and on the coast and ranges of New South Wales, as far south as Macquarie Pass and Jenolan Caves. There is also an isolation population on Cape York Peninsula.[1][2][3]
Uses
The timber is reddish pink to brown.[9] It is prized by woodworkers and woodturners as a rare and exotic timber, often used in wood turnings, knife handles and other specialist items.[10] The rose she-oak has the largest contraction along the grain (12%) of any Australian wood and needs to be dried carefully to get full value as a useful timber.[11]
Ecology
The seeds of A. torulosa have been found to be a food source for the yellow-tailed black cockatoo.[12]
Use in horticulture
It grows from seed,[13] and cut or broken trees will often regenerate from the trunk.
This is a low-maintenance tree that will grow in a variety of soils and tolerate light frosts.[13] In the US, it is suitable for USDA hardiness zones 8–11. It may be susceptible to Armillaria and Phytophthora.[14]
