About Pterostylis bicolor M.A.Clem. & D.L.Jones
Pterostylis bicolor is a terrestrial, perennial, deciduous herb that grows from an underground tuber. It produces a rosette of between five and twelve dark green leaves, with each leaf measuring 10–35 mm (0.4–1 in) long and 3–15 mm (0.1–0.6 in) wide. When in flower, this species produces between three and ten well-spaced, bright shiny green flowers that are 8–11 mm (0.3–0.4 in) long and 4–5 mm wide, growing on a flowering spike that stands 80–300 mm (3–10 in) tall. Between six and eleven stem leaves wrap around the flowering spike. The dorsal sepal and petals form a hood, also called a "galea", that covers the column. The lateral sepals are turned downwards, measure 6–7 mm (0.2–0.3 in) long and 7–8 mm (0.28–0.31 in) wide, are dished, and are joined for most of their length. The labellum is egg-shaped, 3 mm (0.1 in) long and 2 mm (0.08 in) wide, and bears a greenish-black, blunt, ridged, forward-pointing appendage. Flowering occurs from August to November. This species, commonly known as the black-tip greenhood, is widespread across New South Wales and occurs in scattered populations in Victoria. It grows in grassy woodland and forest.
