Argophyllum heterodontum is a plant in the Argophyllaceae family endemic to a small part of north eastern Queensland.

[4][5] The inflorescences are panicles produced in the leaf axils - they are covered with dense, matted, woolly hairs, and may reach up to 9 cm (3.5 in) long.

The type specimen was collected by Forster in 2003 at Walshs Pyramid, about 20 km (12 mi) south of Cairns.

[6][a] Whilst this species is listed by the Queensland Department of Environment and Science as least concern,[1] Bean and Forster recommended in their paper that it should be given the rating of vulnerable, arguing that it may be affected by burning and weed invasion (while most of the population occurs in National Parks, some occurs on freehold land).

[4]: 219 As of 24 January 2024[update], Argophyllum heterodontum has not been assessed by the International Union for Conservation of Nature.
