Taxonomy and naming

Caladenia orestes was first formally described in 2006 by David Jones who gave it the name Arachnorchis orestes. The specimen was collected near Burrinjuck village and the description was published in Australian Orchid Research.[2] In 2010 Gary Backhouse changed the name to Caladenia orestes and published the change in The Victorian Naturalist.[3] The specific epithet (orestes) is an Ancient Greek word meaning "mountaineer"[4] referring to the steep mountain slopes where this species grows.[1]

Distribution and habitat

This spider orchid grows with grasses or shrubs in forest on steep hillsides around Burrinjuck in the south-west slopes region of New South Wales.[1][5]
