Caleana is commonly referred to as the Duck Orchid. This is because, the labellum looks just like a flying duck with its wings raised high. The lip, in particular, looks clearly like the beak of a duck. The flower is reddish brown in colour, and in rare cases, it is greenish with dark spots, and a single leaf appears near the base of the stalk. This small terrestrial orchid is found in the Australia, from Queensland to South Australia, and even Tasmania.
