Pterostylis is a terrestrial deciduous genus of some 70 species.


Plants are found mainly in New Zealand, Australia, Papua New Guinea and New Caledonia.


In a number of species, the flower has a hinged lip that swings backwards when touched by an insect, forming a tube with the column and wings. The trapped insect is then forced to crawl out of the tube, removing the pollinia in the process.


Plants usually grow in cool temperatures with partial shade. In the summer to fall the plant usually goes dormant. During dormancy, the mix dry and until plant begins to sprout. Slowly water the plant until it starts to grows and water regularly. Pot in soil or peat with perlite.


The common name of this orchid is Greenhood because a number of species have green flowers with the dorsal sepal forming a "hood" over the rest of the flower. The name Pterostylis is based on the Greek words meaning winged column (pteron - a wing, stylis - a column).
