Family: Orchidaceae
A very large family. 763 genera. 28,000 species.
Colourful, fragrant flowers.
Perennial herbs with no hard wood.

Pollination. Many specific unusual systems. Chance of pollination is often scare. Therefore, flower remains receptive and blooming for a long period of time.

Tuber of the orchid is spherical and lasts a year. As it groins It produces another tuber to replace itself.
The fruit of the orchid produces 500 tiny seeds.
Joseph Banks was probably the first European botanists to see the greenhood orchid but many of his specimens were lost. Labillardiere was first to formally describe the orchid. A specimen from Bruny island.
Pollination of greenhoods is by tiny flies or mosquitoes. Often the pollinating insect is trapped in the flower.
Three species occur on the Domain.
Species: Pterostylis Curta: Blunt Greenhood.
Species: Pterostylis Nutans: Nodding Greenhood.
Species: Pterostylis Pedunculata: Maroonhoods.
They are similar except for the shape and colour of the flowers.
