About

Apostasia, commonly known as grass orchids, is a genus of eight species of primitive orchids in the family Orchidaceae. They are terrestrial, evergreen, grass-like plants, barely recognisable as orchids and are distributed in humid areas of the Himalayan region, China, India, Sri Lanka, Southeast Asia, New Guinea, and Queensland. They have many narrow leaves and small yellow or white, non-resupinate, star-like flowers usually arranged on a branched flowering stem.

Where it grows

Species in the genus Apostasia are found from north-eastern India, Nepal and Bhutan to southern Japan, and through Southeast Asia to New Guinea and northern Australia. Three species, one of which is endemic, are found in China and one is endemic to Queensland.
