Eucalyptus ravida
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 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 long and wide and petiolate. Adult leaves are the same shade of green on both  sides, glaucous at first, glossy later, long and wide, tapering to a petiole long. The flower buds are arranged in leaf axils in groups of seven on a flattened, unbranched peduncle long, the individual buds sessile or on pedicels up to long. Mature buds are oval, long and 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 long and wide with the valve protruding strongly. Taxonomy and naming. "Eucalyptus ravida" was first formally described in 1991 by Lawrence Alexander Sidney Johnson and Ken  Hill in the journal "Telopea". The specific epithet ("ravida") is from the Latin word "ravidus" meaning "greyish", referring to the appearance of the tree caused by the glaucous twigs. "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. 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. Conservation status. This eucalypt is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
