Description

Eucalyptus drummondii is a mallee that typically grows to a height of Шаблон:Cvt or sometimes a tree to Шаблон:Cvt and forms a lignotuber. It has smooth, powdery bark that is white, pink or grey in colour. Young plants and coppice regrowth have leaves arranged alternately, egg-shaped to more or less round, Шаблон:Cvt long and Шаблон:Cvt wide. Adult leaves are grey-green in colour, narrow elliptical to egg-shaped, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The flower buds are arranged in groups of seven in leaf axils on an unbranched peduncle Шаблон:Cvt long, the individual buds on a pedicel Шаблон:Cvt long. Mature buds are oval, Шаблон:Cvt long and Шаблон:Cvt wide with a conical to rounded operculum with a small point on the top. Flowering mainly occurs from September to December and the flowers are white. The fruit is a woody, hemispherical capsule Шаблон:Cvt long and Шаблон:Cvt wide with the valves extending beyond the level of the rim.[1][2][3][4]

Taxonomy

Eucalyptus drummondii was first formally described in 1867 by George Bentham in his book Flora Australiensis. Bentham based the species on a specimen collected "between Swan River and King George's Sound" by James Drummond.[5][6] The specific epithet (drummondii) honours Drummond.[2]

Distribution and habitat

Drummond's mallee grows in hilly country in soils derived from laterite, sometimes over granite and is found between Eneabba, Wongan Hills, Bridgetown and Woodanilling in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest, Swan Coastal Plain and Warren biogeographic regions.[1][2][3]

Conservation status

Eucalyptus drummondii is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife[1]
