The adult leaves are the same glossy green on both sides, lance-shaped, Шаблон:Convert long, Шаблон:Convert wide on a petiole Шаблон:Convert long. The flower buds are arranged in leaf axils in groups of eleven, thirteen or fifteen on a peduncle Шаблон:Convert long, the individual flowers on a pedicel Шаблон:Convert long. Mature buds are oval, Шаблон:Convert long, Шаблон:Convert wide with a rounded operculum. Flowering mainly occurs from August to October and the flowers are a creamy-white colour.

Taxonomy and naming
Eucalyptus brownii was first formally described by Joseph Maiden and Richard Hind Cambage from specimens collected by Nicholas Daley along the Reid River near Townsville in 1912.[3][4][5][6] The specific epithet (brownii) honours Robert Brown.[4]
Distribution and habitat
Brown's box grows on plains and gentle slopes in central eastern Queensland. It is found between the Connors River south of Sarina, Barcaldine, Hughenden, Charters Towers and Townsville.[7] It is often found as part of open woodland communities along with Eucalyptus persistens with a shrub layer of Eremophila mitchellii, Psydrax oleifolia, Flindersia maculosa and Lysiphyllum species on clay soils in Cainozoic plains or in association with Eucalyptus cambageana and E. crebra in woodlands on low metamorphic rises.[8]
