Taxonomy
Eucalyptus argutifolia was first formally described in 1992 by Peter Grayling and Ian Brooker from a specimen that was collected at Parrot Ridge near Yanchep in 1987. The description was published in the journal Nuytsia.[4][5] The specific epithet (argutifolia) is derived from the Latin words argutus meaning "clear", "bright" or "sharp"[6]Template:Rp and folium meaning "leaf",[6]Template:Rp referring to the shiny adult leaves of this species.[2]
It is placed in the Eucalyptus sub-genus Symphyomyrtus, section Dumaria, series Rufispermae.[2]
Distribution and habitat
Wabling Hill mallee occurs naturally on Wabling Hill and Parrot Ridge to the north of Yanchep and to the south of Seabird on shallow soils of limestone ridges, on slopes and in gullies.[1]

This eucalypt is classified as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and as "Threatened Flora (Declared Rare Flora — Extant)" by the Department of Environment and Conservation (Western Australia).
