About

Corymbia calophylla, commonly known as marri, is a species of flowering plant in the family Myrtaceae and is endemic to the southwest of Western Australia. It is a tree or mallee with rough bark on part or all of the trunk, lance-shaped adult leaves, branched clusters of cup-shaped or pear-shaped flower buds, each branch with three or seven buds, white to pink flowers, and relatively large oval to urn-shaped fruit, colloquially known as honky nuts. Marri wood has had many uses, both for Aboriginal people, and in the construction industry.

Where it grows

Marri is widely distributed in the Southwest region of Western Australia, from north of Geraldton (28° S) to Cape Riche (34° S), and inland beyond Narrogin (32°56′S 117° E). It is found displaying its adaptability to the different environments on the Swan Coastal Plain and the Darling Scarp.

Uses

Marri trees played a significant role in Noongar culture, the applications of its products were adapted and exported by the people occupying the Southwest of Australia.
