Pterostylis nutans has a rosette of between three and six egg-shaped to elliptic leaves, each leaf 15–30 mm (0.6–1 in) long and 10–20 mm (0.4–0.8 in) wide. The leaves are dark green, have a wavy edge and a distinct petiole. A single translucent white flower with green stripes and brown colouration is borne on a flowering spike 80–300 mm (3–10 in) high, the flower strongly "nodding" or leaning forwards. The flowers are 18–25 mm (0.7–1 in) long, 10–14 mm (0.4–0.6 in) wide. There is a wide gap at each side of the flower between the petals and the lateral sepals. The lateral sepals curve forwards, have a tapering tip, 10–18 mm (0.4–0.7 in) long and there is a deeply notched sinus between them. The labellum protrudes from the flower and is 14–18 mm (0.6–0.7 in) long, 4 mm (0.2 in) wide, curved, blunt, green and brown and covered with short, bristly hairs. Flowering occurs from March to December.
