Commersonia bartramia, commonly known as brown kurrajong,[2] is a species of flowering plant in the family Malvaceae and is native to Southeast Asia, the Northern Territory, Queensland and New South Wales.

It is a tree or shrub with heart-shaped to egg-shaped leaves much paler on the lower surface, and sometimes with fine, irregular teeth on the edges.

Commersonia bartramia is a shrub or tree that typically grows to a height of up to 25 m (82 ft), the trunk up to 50 cm (20 in) in diameter and sometimes forming buttress roots.

[2][3] Brown kurrajong was first formally described in 1759 by Carl Linnaeus who gave it the name Muntingia bartramia in Amoenitates Academicae.

[4][5] In 1917, Elmer Drew Merrill changed the name to Commersonia bartramia in his book, An Interpretation of Rumphius's Herbarium Amboinense.
