This greenhood has a translucent white flower with pale to yellowish-green stripes.
Pterostylis patens is a species of greenhood orchid endemic to New Zealand. Flowering have plants spreading leaves on the flowering stem and a single green and white flower with spreading, tapering lateral sepals.

Pterostylis prasina, commonly known as the mallee leafy greenhood, is a plant in the orchid family Orchidaceae and is endemic to southern continental Australia. Non-flowering have a rosette of leaves on a short stalk, but flowering plants lack the rosette and have up to eight pale green and translucent green flowers with darker green lines.

Pterostylis silvicultrix, commonly known as the Chatham Island greenhood or tutukiwi, is a species of orchid which is endemic to Chatham Island and nearby islands. Non-flowering plants have a rosette of leaves but flowering plants have leaves on the flowering stem, some of which reach above the single translucent white flower with dark green stripes. It is similar to Pterostylis banksii which occurs on both of the main islands of New Zealand but that species lacks the orange or reddish-brown tips on the flowers of this species.
Pterostylis stenosepala, commonly known as the narrow-sepalled leafy greenhood, is a plant in the orchid family Orchidaceae and is endemic to New South Wales.

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.
