Choricarpia subargentea) is a rare Australian rainforest tree,[2] growing near Mullumbimby in northeastern New South Wales and from Boonah to Imbil in southeastern Queensland.

The New South Wales habitat of Backhousia subargentea is dry rainforest thickets on hillsides near Mullumbimby.

The trunk can be smooth and glossy, of an attractive orange-brown or pinkish mauve colour, or green where bark has recently been shed.

At other times, the bark sheds irregularly resulting in a mottled trunk, similar to the spotted gum and the leopardwood.

The leaves are opposite, simple and entire, lanceolate or broad with a fine leaf tip, around 4 to 8 cm long.
