Paracaleana - Duck Orchids

These small orchids resemble flying ducks, hence the common name and due to their small size (1-2cm) and drab colour, are generally difficult to locate. As a group, they are relatively common throughout the lower south west and out toward the western wheatbelt. They prefer the same conditions as the hammer orchids, in sandy clearings, and are often found growing together with hammer orchid species.


Paracaleana nigrita - Flying Duck Orchid

The Flying Duck Orchid is distinguished from other Duck Orchids by the calli, which cover more than half of the length of the narrow labellum.The labellum also is distinctly humped about halfway along its length.
