About Pterostylis scabrida Lindl.
Pterostylis scabrida Lindl. is a terrestrial, perennial, deciduous herb that grows from an underground tuber. It produces a rosette of dark green leaves that loosely surround the base of its flowering stem. Each leaf measures 30 to 60 millimeters long and 8 to 10 millimeters wide. A single green and white flower, 20 to 25 millimeters long and 14 to 16 millimeters wide, grows on a rough flowering stem that stands 80 to 250 millimeters high. The dorsal sepal and petals are fused to form a hood, called a "galea", that covers the column. The dorsal sepal is the same length as the petals, curves forward, and ends in a pointed tip. There is a wide gap between the galea and the lateral sepals. The lateral sepals stand erect, have thread-like tips 14 to 16 millimeters long, and have a slightly bulging V-shaped notch called a sinus between them. The labellum is 12 to 15 millimeters long, about 3 millimeters wide, brown, curved, and protrudes above the sinus. Flowering of this species occurs from October to February. This species, commonly known as the rough greenhood, is widespread and common in wet forests, including rainforest, across all of Tasmania.
