Pterostylis pedoglossa, commonly known as the prawn greenhood, is a species of orchid endemic to south-eastern Australia. There is a rosette of leaves at the base and flowering plants have a single white flower with green stripes, sometimes with a brownish tinge on the tip, and a long, thread-like labellum.
Pterostylis pedoglossa is a terrestrial, perennial, deciduous, herb with an underground tuber and a rosette of egg-shaped, greyish-green leaves, each leaf 5–25 mm long and 4–20 mm wide. Flowering plants have a single flower 15–20 mm long and 5–6 mm wide borne on a spike 60–150 mm high. The flowers are white with green stripes, sometimes brown near the tip. The dorsal sepal and petals are fused, forming a hood or "galea" over the column, the galea flat or slightly turned downwards on the tip. The dorsal sepal has a thread-like tip 10–25 mm long. The lateral sepals are held closely against the galea, have an erect, thread-like tip 15–30 mm long and a V-shaped sinus between their bases. The labellum is about 4 mm long, 2 mm wide, greenish, thick, straight and not visible from outside the flower. Flowering occurs from March to June.
