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.
Pterostylis montana is a species of greenhood orchid endemic to New Zealand. Flowering plants have erect, linear leaves on the flowering stem with a single green flower with translucent white stripes and an unusual twisted labellum.
Pterostylis paludosa, commonly known as swamp greenhood, is a species of greenhood orchid endemic to New Zealand. As with similar orchids, plants in flower differ from those that are not. Those not in flower have a rosette of leaves on a short stalk but plants in flower lack a rosette and have a single flower with leaves on the flowering spike. This greenhood has a translucent white flower with pale to yellowish-green stripes.
Pterostylis procera, commonly known as the short-lipped greenhood, is a species of orchid endemic to Queensland. It has a rosette of leaves and when flowering a single translucent white flower with green and reddish markings and a labellum which does not protrude through the lateral sepals.
Pterostylis reflexa, commonly known as the dainty greenhood, is a species of orchid endemic to New South Wales. As with similar greenhoods, the flowering plants differ from those which are not flowering. The non-flowering plants have a rosette of leaves flat on the ground but the flowering plants have a single flower with leaves on the flowering stem. This greenhood has a relatively large white, green and light brown flower with a long, curved dorsal sepal and a protruding labellum.
Pterostylis scoliosa, commonly known as the small kinked greenhood, is a species of orchid endemic to Queensland. As with similar greenhoods, the flowering plants differ from those which are not flowering.

This greenhood has a white, pale green and pale brown flower with a kinked or curved labellum protruding above the sinus between the lateral sepals.
Pterostylis subtilis, commonly known as the thin mountain greenhood, is a species of orchid endemic to New South Wales. It has a rosette of leaves and when flowering a single translucent white flower with dark green lines, a narrow, deeply notched sinus between the lateral sepals and a curved, protruding labellum.
Pterostylis torquata, commonly known as the collared greenhood, is a species of orchid endemic to New South Wales. As with similar greenhoods, the flowering plants differ from those which are not flowering. The non-flowering plants have a rosette of leaves flat on the ground but the flowering plants have a single flower with leaves on the flowering stem. This greenhood has a white flower with dark green and dark brown markings, although in some areas, the flowers lack the brown markings. The sinus between the lateral sepals is platform-like.
Pterostylis divaricata, commonly known as northern striped greenhood, is a species of orchid endemic to northern New South Wales. It grows in colonies of genetically identical plants. As with similar orchids, plants in flower differ from those that are not. Those not in flower have a rosette of leaves that lie flat on the ground. Plants in flower lack a rosette at the base but have up to ten translucent white flowers with green and brown stripes. This greenhood is similar to P. striata but has larger flowers and a longer tip on the dorsal sepal.
