Taxonomy and naming
Diuris oraria was first formally described in 2016 by David Jones and Christopher J. French in Australian Orchid Review, from a specimen collected by French near the western end of the State Barrier Fence in 1999.[4] The specific epithet (oraria) means "of the coast", referring to the coastal or near-coastal distribution of this species.[3][5]
Distribution and habitat
Northern coastal donkey orchid grows in coastal and near-coastal areas on shallow sand over limestone from south of Kalbarri to north of the Zuytdorp Cliffs in the Geraldton Sandplains and Yalgoo bioregions of Western Australia.[1][2][3]
Conservation
Diuris oraria is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.[1]
