Apostasia, commonly known as grass orchids,[2][3] 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.
