A swamp loving species 50–160 mm high with four to six leaves forming a ground-hugging basal rosette 8–16 mm across, two to three cauline leaves and one (rarely two) translucent, green and white flowers 4–5 mm across.

It is distinguished from the related Long-sepaled Snail Orchid (Pterostylis gracillima) by its usually smaller rosette of leaves and swampy rather than granite outcrop habitat.
