Description
Eucalyptus leptocalyx is a mallee that typically grows to a height of Шаблон:Convert and forms a lignotuber. It has smooth brownish over light pink bark. Young plants and coppice regrowth have leaves that are arranged alternately, egg-shaped, Шаблон:Cvt long, Шаблон:Cvt wide and have a petiole. Adult leaves are the same slightly glossy green on both sides, lance-shaped, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The flower buds are arranged in leaf axils in groups of between nine and fifteen on an unbranched peduncle Шаблон:Cvt long, the individual buds on pedicels Шаблон:Cvt long. Mature buds are cylindrical, Шаблон:Cvt long, Шаблон:Cvt wide with a conical operculum Шаблон:Cvt long. Flowering occurs from September to March and the flowers are creamy white. The fruit is a woody, barrel-shaped to cylindrical capsule Шаблон:Cvt long and Шаблон:Cvt wide with the valves enclosed below the rim.[1][2][3][4]
Taxonomy and naming
Eucalyptus leptocalyx was first formally described in 1934 by William Blakely from a specimen collected near Hopetoun by Joseph Maiden in 1909. The description was published in Blakely's book, "A Key to the Eucalypts".[5] The specific epithet (leptocalyx) is derived from the ancient Greek words leptos meaning "thin" or "slender" and calyx meaning "cup" or "calyx".[6]
In 2001, Lawrie Johnson and Ken Hill described two subspecies and published the descriptions in the journal Telopea:[4]
- Eucalyptus leptocalyx Blakely subsp. leptocalyx;[7]
- Eucalyptus leptocalyx subsp. petilipes L.A.S.Johnson & K.D.Hill has smaller leaves, buds and fruit.[8]
Distribution and habitat
Hopetoun mallee grows in coastal and near-coastal areas between the Fitzgerald River National Park and Israelite Bay where it grows in gravelly sandy-clay soils.[1][2]
Conservation status
This mallee is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[1]
