Related Orchid species
Calochilus
Calochilus, commonly known as beard orchids, is a genus of approximately 30 terrestrial orchid species belonging to the family Orchidaceae. These orchids are distinctive for their densely hairy labellum, which gives them their common name. Primarily found in Australia, with some species extending to New Zealand, New Guinea, and New Caledonia, they are terrestrial herbs that typically have a single leaf or are leafless, and reproduce through self-pollination if cross-pollination fails.
Corybas
Corybas, commonly known as helmet orchids, is a genus of about 120 species of small, perennial, terrestrial herbs in the orchid family. Native to a wide range including Australia, New Zealand, Southeast Asia, and the Himalayas, these orchids are distinctive for their single, fungus-like flower, dominated by a large dorsal sepal and labellum, often resembling a helmet.
Cryptostylis
Cryptostylis, commonly known as tongue orchids, is a genus of terrestrial orchids found in South Asia, Southeast Asia, and the South Pacific. These orchids are distinguished by their prominent labellum, which is the most conspicuous part of the flower, and their unique pollination strategy involving wasps attempting to mate with the flowers. At least some species are pollinated through a process called pseudocopulation, where male wasps mistake the flower for a female wasp.
