Pterostylis longicurva, commonly known as the long-tongued greenhood, is a species of orchid endemic to eastern Australia. As with similar greenhoods, plants in flower differ from those that are not. Those not in flower have a rosette of leaves lying flat on the ground, but plants in flower have a single flower with leaves on the flowering stem. This species has a white and green flower with brown markings and a long, curved, brown labellum.
