About Pterostylis concinna R.Br.
Pterostylis concinna R.Br., commonly known as the trim greenhood, produces a rosette of between four and ten dark green, egg-shaped to oblong leaves. Each leaf measures 6–30 mm (0.2–1 in) long and 5–15 mm (0.2–0.6 in) wide. A single dark green and white flower with an orange-red to brownish tip grows on a flowering spike 80–300 mm (3–10 in) high. The flower itself is 12–15 mm (0.5–0.6 in) long and 6–9 mm (0.2–0.4 in) wide. The dorsal sepal and petals are fused and curve forward to form a hood called the "galea" that covers the column, with the dorsal sepal longer than the petals. The pointed tip of the dorsal sepal is 2–3 mm (0.08–0.1 in) long, and the lateral sepals are pressed against the galea. A broad, flat notch (sinus) sits between the lateral sepals, which bear erect, thread-like tips 14–20 mm (0.6–0.8 in) long. The labellum is 7–10 mm (0.3–0.4 in) long, about 4 mm (0.2 in) wide, curved, brown with a notch at its end, and is just visible behind the sinus. Flowering takes place between May and October. This species is distributed in New South Wales south of Mudgee, where it is widespread and locally common in Victoria. It also grows in Tasmania, and only occurs in two colonies in South Australia. It grows in moist forest and coastal scrub, often in sandy soil.
