Description
Eucalyptus extensa is a mallet that typically grows to a height of Шаблон:Cvt but does not form a lignotuber. It has smooth, powdery, grey or grey-brown to green or yellow bark. Adult leaves are narrow to broadly lance-shaped, the same glossy dark green on both sides, 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 an unbranched, flattened peduncle Шаблон:Cvt long, the individual buds on pedicels Шаблон:Cvt long. Mature buds are Шаблон:Cvt long and Шаблон:Cvt wide with a tapering operculum up to five times as long as the floral cup. Flowering has been recorded in March and October and the flowers are yellowish green. The fruit is a woody, hemispherical capsule Шаблон:Cvt long and Шаблон:Cvt wide with a narrow disc and three or four valves that extend well beyond the level of the rim. The seeds are brown to straw-coloured, cuboid to ovoid and Шаблон:Cvt long.[1][2][3]
Taxonomy
Eucalyptus extensa was first formally described in 1991 by the botanists Lawrence Alexander Sidney Johnson and Ken Hill in the journal Telopea, from a specimen collected near the road between Hyden and Norseman.[1][4] The specific epithet is taken from the Latin word extensus meaning "stretched out or extended" in reference to the long opercula on the buds.[2]
Distribution
This mallet occurs on sandplains and undulating areas along the south of Western Australia in the southern Wheatbelt and south western Goldfields-Esperance regions where it grows in red loam, grey sandy loam and sometimes gravelly soils.[3]
Conservation status
This eucalypt is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[3]
