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.

Amherstia nobilis is a tropical tree with large, showy flowers. It is the only member of the genus Amherstia.
