Pterostylis procera is a terrestrial, perennial, deciduous, herb with an underground tuber and a rosette of dark green, wrinkled leaves. Each leaf is 6–60 mm (0.2–2 in) long and 8–20 mm (0.3–0.8 in) wide. When flowering, there is a single translucent white flower with green and reddish markings, 40–50 mm (1.6–2.0 in) long and 18–25 mm (0.7–1 in) wide which is borne on a flowering spike 200–350 mm (8–10 in) high. The dorsal sepal and petals are fused to form a hood or "galea" over the column, the dorsal sepal slightly longer than the petals and sharply pointed. There is a wide gap at each side of the flower between the petals and lateral sepals. The lateral sepals are erect or turned backwards with a tapering tip 20–25 mm (0.8–1 in) long and there is a broad bulging sinus with a small notch between them. The labellum does not protrude above the sinus. Flowering occurs from February to May.
