Appearance

Cryptostylis erecta is a terrestrial, perennial, deciduous, herb with one to several egg-shaped to lance-shaped leaves 60–130 mm (2–5 in) long and 13–30 mm (0.5–1 in) wide on a petiole 10–100 mm (0.4–4 in) long. The leaves are dark green on the upper surface and purple below. Between two and twelve flowers 25–30 mm (0.98–1.2 in) long and 10–15 mm (0.4–0.6 in) wide are borne on a flower spike 300–800 mm (10–30 in) high. The most prominent feature of the flower is its hood- or bonnet-shaped labellum which is 20–30 mm (0.8–1 in) long and 10–15 mm (0.4–0.6 in) wide, greenish to lilac-coloured with a network of purple or maroon veins and a few purple spots. The base of the labellum is narrow and surrounds the column. The sepals are green, 18–25 mm (0.7–1 in) and 1.5–2 mm (0.06–0.08 in) and the petals are 10–15 mm (0.4–0.6 in) and about 1 mm (0.04 in) wide, all spreading apart from each other. Flowering occurs from September to April.

Its range extends from the Kroombit Tops National Park in Queensland south through New South Wales to east Gippsland in Victoria. It occurs mostly in coastal districts, although it is also found in the Upper Blue Mountains.
