A swamp loving species 30–140 mm high with three to five basal leaves that form an ascending rosette 12–36 mm across, two to five cauline leaves and one (rarely two) translucent, green and white flowers 3.5–4 mm across.

It is distinguished from the closely related Clubbed Snail Orchid (Pterostylis glebosa) predominantly by its south-easterly distribution. Otherwise they are very similar and may be forms of the same species.
