Eucalyptus perriniana
Template:Short description Template:Speciesbox
Eucalyptus perriniana, commonly known as spinning gum, is a tree or mallee which is native to New South Wales, the Australian Capital Territory, Victoria and Tasmania.[1] Spinning gum is a sub-alpine species and grows in areas which are normally snow covered for several months in winter. However domestic cultivars can grow in almost any temperate climate.
Description
Eucalyptus perriniana is a tree which sometimes grows to a height of Script error: No such module "convert". or a mallee with smooth, copper-coloured bark which often turns white, grey or greenish as it ages before being shed in short ribbons each year. Its adult leaves are lance-shaped, greyish-green, Script error: No such module "convert". long and Script error: No such module "convert". wide. The juvenile leaves are arranged in opposite pairs, more or less round and lack a peduncle. The flowers are arranged in groups of three and the flower buds are Script error: No such module "convert". long and Script error: No such module "convert". in diameter. The flower caps are cone-shaped or hemispherical and the fruit is Script error: No such module "convert". long and Script error: No such module "convert". in diameter.[1][2][3][4]
Taxonomy and naming
Eucalyptus perriniana was first formally described in 1894 by Leonard Rodway from an unpublished description by Ferdinand von Mueller. Rodway's description was published in Papers and Proceedings of the Royal Society of Tasmania.[5][6] Rodway did not give a reason for the specific epithet (perriniana) but George Samuel Perrin was Conservator of Forests in Tasmania in 1886 and 1887 before being appointed Conservator of Forest in Victoria in 1888.[7] The common name refers to the detached but persistent juvenile leaves that can spin in the wind.[8]
Distribution and habitat
Spinning gum grows in woodland on high, cold plains in New South Wales, the Australian Capital Territory, Victoria and Tasmania.[1][2][3]
Conservation
This eucalypt is listed as "rare" under the Tasmanian Government Threatened Species Protection Act 1995. Only about one thousand individual plants are known from that state.[3]
Uses
Catechin-7-O-glucoside and catechin-5-O-glucoside can be produced by biotransformation of (+)-catechin by cultured cells of E. perriniana.[9]
