Caleana nigrita (Flying Duck Orchid)

Caleana nigrita, commonly known as the small duck orchid or flying duck orchid is a species of orchid endemic to the south-west of Western Australia. It is the most common of the flying duck orchids and has the widest distribution of the Western Australian species. It has a single smooth leaf and is distinguished from the others by its labellum which has a hump in the middle and calli covering two thirds of its outer end. Its dull colouration makes it difficult to find, especially in areas that are blackened by fire.

Caleana nigrita is found in near-coastal areas between Eneabba and Esperance in the Swan Coastal Plain, WarrenAvon Wheatbelt, Esperance Plains, Jarrah Forest and Mallee biogeographic regions where it usually grows in woodland and shrubland.
