Corymbia greeniana
Corymbia greeniana is a species of tree that is endemic to northern Australia. It has rough bark on some or all of the trunk and larger branches, smooth bark above, broadly lance-shaped to egg-shaped adult leaves, flower buds usually in groups of seven, creamy white flowers and urn-shaped fruit with a distinct neck. Description. "Corymbia greeniana" is a tree that typically to a height of and forms a lignotuber. It has rough, loose, flaky, tessellated brownish bark on some or all of the trunk, sometimes also on the larger branches, smooth white and pale grey  bark above. Young plants and coppice regrowth have dull green, more or less round to broadly egg-shaped leaves that are long, wide and petiolate. Adult leaves are more or less the same shade of green on both sides, broadly lance-shaped to egg-shaped, long and wide on a petiole long. The flower buds are arranged on the ends of branchlets on a branched peduncle long, each branch of the peduncle with seven, sometimes nine buds, on pedicels long. Mature buds are oval to pear-shaped, long and wide with a rounded operculum that has a small point in  the centre. Flowering occurs from January to May and the flowers are creamy white. The fruit is a woody urn-shaped capsule long and wide with a short vertical neck and the valves enclosed in the fruit. Taxonomy and naming. This eucalypt was first formally described in 1987 by Denis Carr and Stella Carr and was given the name "Eucalyptus greeniana". In 1995 Ken Hill and Lawrie Johnson changed the name to "Corymbia greeniana". The specific epithet ("greeniana") honours Marjorie Free (née Marjorie Green), an herbarium curator. Distribution and habitat. "Corymbia greeniana" grows on red and yellow sand soils, sometimes  on basalt or volcanic rocks in open savannah woodland. It occurs in the Kimberley, Western Australia region of Western Australia and east through the Top End between Katherine and Mataranke in the Northern Territory to Doomadgee and scattered areas of the southern Cape York Peninsula in Queensland.
