Pterostylis pulchella (Pterostylis pulchella)
Description
Pterostylis pulchella is a terrestrial, perennial, deciduous, herb with an underground tuber and when not flowering, a rosette of between three and five egg-shaped leaves lying flat on the ground. Each leaf is 10–25 mm (0.4–1 in) long and 6–15 mm (0.2–0.6 in) wide. Flowering plants have a single flower 25–35 mm (0.98–1.4 in) long and 15–18 mm (0.6–0.7 in) wide which leans slightly forwards on a flowering stem 60–150 mm (2–6 in) high with between three and five spreading stem leaves. The flowers are greenish-white near the base, reddish-brown above. The dorsal sepal and petals are fused, forming a hood or "galea" over the column, the dorsal sepal with a thread-like tip 5–12 mm (0.2–0.5 in) long. The lateral sepals are fused near their base, partly closing off the front of the flower and have erect, thread-like tips 30–35 mm (1.2–1.4 in) long. The labellum is 16–18 mm (0.6–0.7 in) long, about 4 mm (0.2 in) wide, curved, dark reddish-brown and protrudes above the sinus. Flowering occurs from February to May
