Taxonomy and naming

Diuris porphyrochila was first formally described in 2016 by David Jones and Christopher French in Australian Orchid Review from specimens collected near Wellington Dam in 1997.[4] The specific epithet (porphyrochila) means "purple lip", referring to the colour of the labellum.[3]

Distribution and habitat

Yalgorup donkey orchid grows in forest in sand in near-coastal areas from south of Mandurah to Busselton, possibly as far south as Margaret River in the Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia.[1][2][3]

Conservation

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