Eucalyptus ravida is a species of small mallet that is endemic to Western Australia. It has smooth, shiny bark, lance-shaped adult leaves, flower buds in groups of seven, white flowers and conical to hemispherical fruit.
Description
Eucalyptus ravida is a mallet that has fluted stems and typically grows to a height of Шаблон:Cvt but does not form a lignotuber. It has smooth shiny greyish to brownish bark. Young plants and coppice regrowth have glaucous branchlets and bluish green to glaucous leaves that are Шаблон:Cvt long and Шаблон:Cvt wide and petiolate. Adult leaves are the same shade of green on both sides, glaucous at first, glossy later, Шаблон:Cvt long and Шаблон:Cvt wide, tapering to a petiole Шаблон:Cvt long. The flower buds are arranged in leaf axils in groups of seven on a flattened, unbranched peduncle Шаблон:Cvt long, the individual buds sessile or on pedicels up to Шаблон:Cvt long. Mature buds are oval, Шаблон:Cvt long and Шаблон:Cvt wide with a conical operculum. Flowering occurs from September to December and the flowers are creamy white. The fruit is a woody, conical to hemispherical capsule Шаблон:Cvt long and Шаблон:Cvt wide with the valve protruding strongly.[1][2][3]
Taxonomy and naming
Eucalyptus ravida was first formally described in 1991 by Lawrence Alexander Sidney Johnson and Ken Hill in the journal Telopea.[3][4] The specific epithet (ravida) is from the Latin word ravidus meaning "greyish", referring to the appearance of the tree caused by the glaucous twigs.[3]
Eucalyptus ravida is one of the six true gimlet species that have buds in groups of seven. The other true gimlets are E. campaspe , E. effusa , E. salubris, E. terebra and E. tortilis. The non-glaucous E. salubris is easily distinguished from E. ravida and E. campaspe both of which have conspicuously glaucous branchlets.[1]
Distribution and habitat
This mallet is found on undulating plains and shallow depressions between Callion, Norseman and Zanthus in the Avon Wheatbelt, Coolgardie, Mallee and Murchison biogeographic regions.[2]
Conservation status
This eucalypt is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[2]
