Taxonomy and naming
Diuris curta was first formally described in 2006 by David Jones from a specimen collected near Hat Head and the description was published in Australian Orchid Research.[2] The specific epithet (curta) is a Latin word meaning "short",[3] referring to the short habit of this orchid, which is probably a result of adaptation to the exposed environment.[1]
Distribution and habitat
This orchid grows on coastal headlands between Byfield and Hat Head, often in places exposed to the sea.[1]
Conservation
Invasion by weeds including bitou bush and native shrubs in the absence of fire threaten D. curta.[1]
