Description
Eucalyptus semiglobosa is a shrub Шаблон:Cvt tall or mallee that typically grows to a height of Шаблон:Cvt, and forms a lignotuber. It has smooth grey or light brown bark. Young plants and coppice regrowth have stems that are square in cross-section and leaves that are the same shade of green on both sides, elliptic to egg-shaped, Шаблон:Cvt and Шаблон:Cvt wide. Adult leaves are broadly lance-shaped, the same shade of dull to slightly glossy green on both sides, Шаблон:Cvt and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The flower buds are arranged in leaf axils in groups of seven on an unbranched peduncle Шаблон:Cvt long, the individual buds on pedicels Шаблон:Cvt long. Mature buds are oval, ribbed, Шаблон:Cvt and Шаблон:Cvt wide with a hemispherical operculum about the same length as the floral cup. The fruit is a woody, shortened spherical or hemispherical, ribbed or wrinkled capsule Шаблон:Cvt and Шаблон:Cvt wide with the valves protruding above the rim.[1][2]
Taxonomy and naming
This species was first formally described in 1976 by Ian Brooker in the journal Nuytsia and given the name Eucalyptus goniantha subsp. semiglobosa.[3][4] In 1992, Lawrie Johnson and Ken Hill raised the subspecies to species status as E. semiglobosa in the journal Telopea and the change has been accepted at the Australian Plant Census.[5] The specific epithet (semiglobosa) is from the Latin semi- meaning "half" and globosa meaning "globose",[6] referring to the operculum.[1]
Distribution and habitat
This eucalypt is found in scattered populated growing on shallow sand over granite between the Cape Le Grand and Cape Arid National Parks in the Esperance Plains and Mallee biogeographic regions.[1][7]
Conservation status
Eucalyptus semiglobosa is classified as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife[7] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[8]
