Pterostylis hamata (Pterostylis hamata)
Description
Pterostylis hamata, is a terrestrial, perennial, deciduous, herb with an underground tuber. It has a rosette of between six and fifteen egg-shaped leaves at the base of the flowering spike, each leaf 20–30 mm (0.8–1 in) long and 6–12 mm (0.2–0.5 in) wide. Between two and twelve transparent flowers with green and brown markings, each flower 19–22 mm (0.7–0.9 in) long and 7–8 mm (0.3–0.3 in) wide, are borne on a flowering spike 200–400 mm (8–20 in) tall. Two to eight stem leaves are wrapped around the flowering spike. The dorsal sepal and petals form a hood or "galea" over the column with the dorsal sepal having an downturned, thread-like point 4–7 mm (0.2–0.3 in) long. The lateral sepals turn downwards and are joined for about half their length and shallowly dished with the edges curved inwards. The lateral sepals also suddenly narrow to thread-like tips 12–15 mm (0.5–0.6 in) long which curve forwards with hooked ends. The labellum is brown, fleshy, insect-like, about 5 mm (0.2 in) long, 2 mm (0.08 in) wide and grooved and has long and short bristles around its edges. Flowering occurs from September to November.
