Description
Eucalyptus ceratocorys is a mallee, rarely a straggly tree, that typically grows to a height of Шаблон:Convert and forms a lignotuber. It has rough flaky bark near the base of the trunks and shaggy, ribbony bark above that does not shed cleanly. Young plants and coppice regrowth have stems that are square in cross-section and greyish green, egg-shaped leaves Шаблон:Cvt long and Шаблон:Cvt wide. Adult leaves are the same glossy green on both sides, lance-shaped, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The flower buds are usually arranged in groups of seven or nine on a peduncle Шаблон:Cvt long, the individual buds on a pedicel Шаблон:Cvt long. Mature buds are oval to pear-shaped with ridges along the sides, Шаблон:Cvt long and Шаблон:Cvt wide with a beaked operculum Шаблон:Cvt long. Flowering occurs between July and December and the flowers are white to cream coloured, rarely red. The fruit is a woody, cylindrical capsule Шаблон:Cvt long and Шаблон:Cvt wide with ridges along the sides. The fruit have a pedicel Шаблон:Cvt long.[1][2][3]
Taxonomy and naming
The horn-capped mallee was first formally described in 1934 by William Blakely who gave it the name Eucalyptus angulosa var. ceratocorys from a specimen collected near Comet Vale. Blakely published the description in his book A key to the Eucalypts.[4] In 1988, Lawrie Johnson and Ken Hill raised the variety to species status as Eucalyptus ceratocorys.[5] The specific epithet (ceratocorys) is derived from the Ancient Greek words keras meaning "horn"[6]Шаблон:Rp and korys meaning "helmet",[6]Шаблон:Rp referring to the beaked operculum of this species.[1]
Distribution and habitat
Eucalyptus ceratocorys grows in sandy soil in shrubland between Koorda and the southern fringe of the Great Victoria Desert in the southern Wheatbelt and Goldfields-Esperance regions of Western Australia.[2]
Conservation status
This eucalypt is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[2]
