Шаблон:Short description Шаблон:Speciesbox
Eucalyptus preissiana, commonly known as bell-fruited mallee,[1] is a species of small tree or shrub that occurs in an area between Albany and Esperance in Western Australia. It has a spreading habit, smooth bark, elliptical to egg-shaped or oblong leaves, flower buds in groups of three, yellow flowers and cup-shaped, conical or bell-shaped fruit.
Description
Eucalyptus preissiana is a mallee that typically grows to a height of Шаблон:Cvt with a sprawling habit, and forms a lignotuber. It has smooth, greyish and brown bark. Young plants and coppice regrowth have stems that are square in cross-section and elliptical to egg-shaped leaves that are the greyish green, Шаблон:Cvt long, Шаблон:Cvt wide and arranged in opposite pairs. Adult leaves are sometimes arranged alternately, the same shade of dull greyish green on both sides, elliptical to egg-shaped or oblong, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The flower buds are arranged in leaf axils on a flattened, unbranched peduncle Шаблон:Cvt long, the individual buds on pedicels Шаблон:Cvt long. Mature buds are oval, Шаблон:Cvt long and Шаблон:Cvt wide with a conical to rounded operculum. Flowering occurs from September to November and the flowers are yellow. The fruit is a woody, cup-shaped, conical or bell-shaped capsule Шаблон:Cvt long and Шаблон:Cvt wide with lobes between the valves.[1][2][3][4][5]
Taxonomy and naming
Eucalyptus preissiana was first formally described in 1844 by the Johannes Conrad Schauer and the description was published in Lehmann's book Plantae Preissianae.[6] The specific epithet honours Ludwig Preiss who collected the type specimen near Cape Riche in 1840.[7]
In 1995 Ian Brooker and Andrew Slee described two subspecies and the names have been accepted by the Australian Plant Census:[8]
- Eucalyptus preissiana subsp. lobata Brooker & Slee[9] differs from subspecies preissiana in having large lobes between the valves of the fruit;[8]
- Eucalyptus preissiana Schauer subsp. preissiana[10] has fruit that lack lobes or have small lobes below the rim of the fruit.[8]
Distribution
Bell-fruited mallee is found in coastal and sub-coastal areas among limestone and laterite and grows in gravelly sandy-clay soils. It occurs in coastal and near-coastal areas from the Stirling Range to the Fitzgerald River National Park and almost to Esperance to the east.[1][2] Subspecies lobata only occurs in coastal areas in a few places between Esperance and Hopetoun.[2]
Conservation status
Subspecies preissiana is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife,[11] but subspecies lobata is classified as "Priority Four" by the Government of Western Australia Department of Parks and Wildlife,[12] meaning that is rare or near threatened.[13]
Use in horticulture
Bell-fruited mallee can be cultivated in temperate areas of Australia but performs poorly in tropical environments. It is propagated from seeds and germinates easily. It prefers a position in full sun and in well-drained soils.[4]
