About

Eucalyptus oligantha, commonly known as the broad-leaved box, is a species of tree that is native to the Kimberley region of Western Australia and parts of the Northern Territory. It has rough, fibrous or flaky greyish bark, broadly egg-shaped to almost round adult leaves that are lost in the dry season, flower buds in groups of three or seven, creamy yellow to whitish flowers and cup-shaped to more or less cylindrical, bell-shaped or conical fruit.

Where it grows

Broad-leaved box grows on flats and slopes, often near watercourses in forest and woodland in the Kimberley region between Wyndham and Derby with a few scattered populations in the Northern Territory, including some of its offshore islands.
