Шаблон:Short description Шаблон:Speciesbox
Eucalyptus distans, commonly known as the Katherine box,[1] is a species of small tree that is endemic to northern parts of Australia. It has rough, fibrous grey bark, dull, narrow lance-shaped adult leaves, flower buds in groups of seven, creamy white flowers and cup-shaped to hemispherical or conical fruit.
Description
Eucalyptus distans is a tree that typically grows to a height of Шаблон:Cvt and forms a lignotuber. It has rough, fibrous, finely fissured grey bark with white patches. Young plants and coppice regrowth have narrow lance-shaped leaves Шаблон:Cvt long and Шаблон:Cvt wide. Adult leaves are the same dull, light green to grey-green colour on both sides, lance-shaped to curved, 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 on a thin, branched peduncle Шаблон:Cvt long, the individual buds on a pedicel up to Шаблон:Cvt long. Mature buds are cylindrical to oval, Шаблон:Cvt long and about Шаблон:Cvt wide with a conical to rounded operculum. Flowering occurs between March and April and the flowers are creamy white. The fruit is a woody cup-shaped to hemispherical or conical capsule Шаблон:Cvt long and wide on a pedicel up to Шаблон:Cvt long. The valves extend well beyond the rim and the seeds are blackish brown.[2][3][4]
Taxonomy and naming
Eucalyptus distans was first formally described in 1980 by Ian Brooker, Douglas Boland and David Kleinig from samples gathered near Katherine Gorge by Clyde Dunlop in 1977 and the description was published in Australian Forest Research.[5][6] Eucalyptus epruinata was described in 2000 by Ken Hill and Lawrie Johnson in the journal Telopea from specimens collected in Queensland but the name is listed as a synonym by the Australian Plant Census.[7] The specific epithet (distans) is a Latin word meaning "remote", "far apart" or "distant"[8] indicating that this species is separated from the similar E. microtheca.[2]
Distribution and habitat
Katherine box grows on low stony ridges. There are scattered populations through the Northern Territory between Katherine and Gove with disjunct populations near Fitzroy Crossing in Western Australia and near Croydon in Queensland.[1][2][4]
Conservation status
Eucalyptus distans is classified as "Priority One" by the Government of Western Australia Department of Parks and Wildlife,[1] meaning that it is known from only one or a few locations which are potentially at risk.[9] In 2019 the International Union for the Conservation of Nature listed E.Шаблон:Nbspdistans as a least concern species with a severely fragmented although stable population with a total estimated area of occupancy of Шаблон:Cvt and an estimated extent of occurrence of Шаблон:Cvt .[10]
