Taxonomy and naming
Diuris hazeliae was first formally described in 2013 by David Jones and Christopher J. French in Australian Orchid Research, from a specimen collected at Tampu, near Karroun Hill Nature Reserve.[4] The specific epithet (hazeliae) honours the plant collector Hazel King from the property "Kings Park", where the type specimens were collected.[3]
Distribution and habitat
Yellow granite donkey orchid grows on and around granite outcrops in a broad band between East Yuna, Paynes Find, Coolgardie, Norseman and Esperance, in the Avon Wheatbelt, Coolgardie, Geraldton Sandplains, Mallee and Yalgoo bioregions of south-western Western Australia.[2][3][1]

Diuris hazeliae is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.[1]
