Taxonomy and naming

Diuris oporina was first formally described in 1991 by David Jones from a specimen collected near Watsonville, Queensland on the Atherton Tableland and the description was published in Australian Orchid Research.[4] The specific epithet (oporina) is derived from the Ancient Greek word oporinos meaning "autumnal",[5] referring to the flowering period of this species.[3]

Distribution and habitat

The autumn donkey orchid grows on ridges and sloped in forest and woodland on the drier parts of the Atherton and Evelyn tablelands.[1][3]
