Taxonomy

This species was first described, along with a number of other new species in this genus, in 2018 by the Australian botanists Anthony Bean and Paul Forster who published it in the Journal Austrobaileya. The type specimen was collected by Forster in 2003 at Walshs Pyramid, about 20 km (12 mi) south of Cairns, Queensland.[3][4]

Etymology

The genus name Argophyllum is derived from Ancient Greek Árgos meaning white or shining, and phúllon meaning leaf. It refers to the white colouration of the underside of the leaves.[4] The species epithet heterodontum is from héteros meaning different, and odóntos meaning tooth. It refers to the variable size of the teeth on the leaf margin.[2][4]

Distribution and habitat

A. heterodontum is restricted to a small area of the Wet Tropics of Queensland, mostly in the area of Walsh's Pyramid, and with a disjunct population around Butchers Creek Falls to the south-west.[3][4] It inhabits open forest and the margins of rainforest on a variety of soils.[3][4]

Conservation

This species is listed by the Queensland Department of Environment and Science as least concern.[1] As of 30 August 2021^[update], it has not been assessed by the IUCN.
