Taxonomy and naming
Diuris recurva was first formally described in 1991 by David Jones from a specimen collected near Northampton, and the description was published in Australian Orchid Review.[5] The specific epithet (recurva) is a Latin word meaning "recurved", referring to the petals and lateral sepals that are curved backwards.[2]
Distribution and habitat
The mini donkey orchid grows mostly in winter-wet heath between Badgingarra and Kalbarri in the Avon Wheatbelt, Geraldton Sandplains and Jarrah Forest biogeographic regions.[3][6]
Conservation
Diuris recurva is classified as "Priority Four" by the Government of Western Australia Department of Parks and Wildlife,[6] meaning that is rare or near threatened.[7]
