About

Pterostylis micromega, commonly known as the swamp greenhood, is a species of greenhood orchid endemic to New Zealand. Both flowering and non-flowering plants have a rosette of leaves while flowering plants also have a single, relatively large whitish flower with a pointed dorsal sepal. The flower colour and pointed dorsal sepal are unique in New Zealand Pterostylis.

Where it grows

The swamp greenhood grows in swampy areas sometimes in colonies of up to fifty. It has been recorded on the North, South and Chatham Islands but its distribution is now much reduced. It has not been observed on Chatham Island since the 1800s but is still present near Waikato, on the Volcanic Plateau, near Wanganui and in the Wairarapa.
