Brid, GipP, WaP. Scattered in near-coastal areas of Victoria west from Wilsons Promontory where found in swamps and watercourses dominated by Leptospermum lanigerum.
This is the last species of Corybas to flower in Victoria.
Can be distinguished from C. diemenicus by the labellum auricles which are obscured by the lamina, the later flowering period and unique habitat.
