black-tip greenhood

Pterostylis bicolor, commonly known as the black-tip greenhood, is a plant in the orchid family Orchidaceae and is endemic to south-eastern Australia. It has a rosette of leaves and when flowering, three to ten well-spaced, bright green flowers with a blunt, greenish-black appendage on the labellum. It is similar to the swan orchid, Pterostylis cycnocephala but that species has a beak-like appendage and crowded flowers.
