Шаблон:Short description Шаблон:Speciesbox
Eucalyptus georgei, commonly known as Hyden blue gum,[1] is a species of tree or mallet that is endemic to Western Australia. It has smooth bark, glossy green, lance-shaped adult leaves, glaucous flower buds in groups of between seven and eleven, creamy white flowers and conical to cup-shaped fruit.
Description
Eucalyptus georgei is a tree or mallet that typically grows to a height of Шаблон:Cvt but does not form a lignotuber. It has smooth, pale grey and coppery-orange coloured bark that detaches in long ribbons. Young plants and coppice regrowth have glaucous, egg-shaped to broadly lance-shaped leaves that are Шаблон:Cvt long and Шаблон:Cvt wide. Adult leaves are either glossy green or glaucous, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The flower buds are arranged in leaf axils in groups of seven, nine or eleven on a thick, glaucous, unbranched peduncle Шаблон:Cvt long, the individual buds on pedicels about Шаблон:Cvt long. Mature buds are glaucous, oval to pear-shaped, about Шаблон:Cvt long and Шаблон:Cvt wide with a conical or rounded operculum. Flowering occurs between February and March and the flowers are creamy white. The fruit is a woody, usually glaucous, conical to cup-shaped capsule Шаблон:Cvt long and Шаблон:Cvt wide with the valves near rim level. The seeds are glossy red-brown, flattened oval and Шаблон:Cvt long.[1][2][3][4]
Taxonomy and naming
Eucalyptus georgei was first formally described in 1978 by Ian Brooker and Donald Blaxell from a specimen collected by Blaxell in 1975, Шаблон:Cvt east of Hyden on the track to Norseman.[4][5]
In 1993 Brooker and Stephen Hopper described two subspecies and the names have been accepted by the Australian Plant Census:[6]
- Eucalyptus georgei subsp. fulgida Brooker & Hopper[7][8] differs from subspecies georgei in having shiny green, non-glaucous leaves and smaller, shorter fruits;
- Eucalyptus georgei Brooker & Blaxell subsp. georgei.[9][10]
The specific epithet honours the botanist Alex George for his assistance to both the authors.[4] The epithet fulgida is from the Latin fulgidus meaning "shining".[4]
Distribution
The Hyden blue gum is found in a small area where the Wheatbelt region meets the Goldfields-Esperance region between Hyden to east of Kalgoorlie. It grows on lateritic rises and in depressions in calcareous loam, clayey sand or sandy soils.[1]
