Pterostylis timothyi, commonly known as the brittle snail orchid or fawn snail orchid is a species of orchid which is endemic to the south-west of Western Australia. It has a rosette of leaves at its base, and when flowering, a single green, fawn and white with erect lateral sepals.
Pterostylis timothyi is a terrestrial, perennial, deciduous, herb with an underground tuber and a rosette of bright green, pointed leaves 5–11 mm (0.2–0.4 in) long and 4–6 mm (0.16–0.24 in) wide with prominent veins. A single bright green, fawn and white flower, 11–13 mm (0.4–0.5 in) long and 3–4 mm (0.1–0.2 in) wide is borne on a stalk 60–130 mm (2–5 in) high. The dorsal sepal and petals are fused, forming a hood or "galea" over the column, the sepal and petals with a sharp point on the end. The lateral sepals are erect, in close contact with the galea and have thread-like tips 12–18 mm (0.5–0.7 in) long. The sinus between the lateral sepals has a small notch in the centre a brownish central area. The labellum is 3–4 mm (0.1–0.2 in) long, about 2 mm (0.08 in) wide and hidden inside the flower. Flowering occurs in July and August.
