Southern greenhood

Pterostylis australis, commonly known as the southern greenhood, is a species of orchid endemic to New Zealand. Unlike many other greenhood orchids, this species lacks a rosette of leaves but instead only has leaves on the flowering stem. The leaf's shape differs according to it position on the stem and there is a single green and white-striped flower. This greenhood occurs on both of the main islands of New Zealand and often forms large colonies.
