Eucalyptus cooperiana
Eucalyptus cooperiana, commonly known as the many-flowered mallee, is a species of mallee that is endemic to an area along the south coast of Western Australia. It is described as being "of striking appearance by reason of its smooth, white bark and acutely angled branchlets". It has lance-shaped adult leaves, flower buds in groups of between nine and thirteen or more, creamy yellow flowers and urn-shaped fruit. Description. "Eucalyptus cooperiana" is a mallee that typically grows to a height of and has a lignotuber. The bark is smooth, powdery and white over pale grey to  pinkish over most of the tree with some rough grey fibrous bark at the base. Charles Gardner described the species as being "of striking appearance by reason of its smooth, white bark and acutely angled branchlets". Young plant and coppice regrowth have sessile, elliptic to lance-shaped leaves arranged in opposite pairs, long and wide. Adult leaves are arranged alternately, lance-shaped, the same glossy green or bluish on both sides, long and wide on a petiole long. The flower buds are arranged in groups of nine, eleven or thirteen or more in leaf axils on a downturned peduncle long , the individual buds on a pedicel long. Mature buds are oval or cylindrical, long and wide with a flattened to rounded operculum that is shorter than the floral cup. Flowering occurs between October and December or between January and March and the flowers are creamy yellow. The fruit is a woody, urn-shaped capsule long and wide on a down-turned pedicel long.

The type specimen was collected by George Maxwell. The specific epithet ("cooperiana ) honours Ellwood Cooper, a Californian horticulturalist, who introduced many species of Eucalyptus" to the United States and wrote "Forest Culture and Eucalyptus trees". Distribution and habitat. The many-flowered mallee is found on sand plains along south coast of Western Australia between Esperance and Israelite Bayin the Goldfields-Esperance region where it grows in sandy-clay soils over limestone.
