Corybas globulus

Corybas globulus is a terrestrial, tuberous, herbaceous plant that forms loose clonal colonies. It has a single heart-shaped leaf 15–30 mm (0.6–1 in) long, 10–30 mm (0.4–1 in) wide and bright green with reddish edges and lower surface. The flower is more or less spherical and 10–11 mm (0.39–0.43 in) on a pinkish peduncle 5–8 mm (0.2–0.3 in) long. The dorsal sepal is dark reddish purple, 10–12 mm (0.4–0.5 in) long on a stalk 5–6 mm (0.20–0.24 in) long. The lateral sepals are 10–11 mm (0.39–0.43 in) long and the petals are about 5 mm (0.2 in) long, all in close contact with the labellum. The labellum is about as long as the dorsal sepal, tube-shaped and has three lobes. There are crowded rows of pink to red calli about 1 mm (0.04 in) long in a ridge about 2 mm (0.08 in) wide around the edge of the labellum. Flowering occurs from early May to mid June.

The orchid grows in open forest with a dense shrubby understorey. It is only known from the Washpool and Gibraltar Range National Parks.
