Taxonomy and naming

Diuris luteola was first formally described in 1991 by David Jones and Bruce Gray from a specimen collected on the Atherton Tableland near Herberton and the description was published in Australian Orchid Research.[3] The specific epithet (luteola) is a Latin word meaning "yellowish",[4] referring to the colour of the flowers of this species.[2]

Distribution and habitat

The northern doubletail grows in shallow soil in grassy forest from Mount Windsor adjacent to the Daintree National Park to the Blackdown Tableland.[1][2]
