Taxonomy and naming

Diuris perialla was first formally described in 2012 by David Jones and Christopher J. French in Australian Orchid Review, from a specimen collected by French in 1998. The specific epithet (perialla) means "before all others", referring to the species' early flowering.

Distribution and habitat

Early donkey orchid grows in low, shrubby heathland on laterite breakaways, in the area between Regans Ford, Mogumber, Northampton and Mingenew in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia.

Conservation

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