Taxonomy and naming

Diuris tinkeri was first formally described in 2013 by David Jones and Christopher J. French in Australian Orchid Review, from a specimen collected in the Western Flora Caravan Park near Eneabba in 1997. The specific epithet (tinkeri) honours Allan Tinker, who recognised the distinctiveness of the species.

Distribution and habitat

Arrowsmith donkey orchid grows in woodland, shrubland and kwongan in near-coastal areas, from near Geraldton to near Yanchep in the Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia.
