Ruddy greenhood (Pterostylis squamata)
Description
Pterostylis squamata, is a terrestrial, perennial, deciduous, herb with an underground tuber. Non-flowering plants have a rosette of between four and eight oblong leaves, each leaf 10–30 mm (0.4–1 in) long and 7–12 mm (0.3–0.5 in) wide. Flowering plants have up to ten translucent green flowers with reddish-green markings, on a flowering spike 100–300 mm (4–10 in) high. There are between two and six stem leaves wrapped around the flowering spike. The dorsal sepal and petals are fused, forming a hood or "galea" over the column with the dorsal sepal having an upturned, thread-like tip about 2 mm (0.08 in) long. The lateral sepals are about the same width as the galea, egg-shaped and turned downwards, joined for part of their length and taper to a narrow or thread-like tip 4–7 mm (0.2–0.3 in) long. The labellum is insect-like, about 4 mm (0.2 in) long, 2 mm (0.08 in) wide, dark reddish brown and fleshy. There are five to seven hairs up to 2 mm (0.08 in)on each side of the labellum and many shorter hairs on the "head" end. Flowering occurs from October to March.
