Pterostylis scabra, commonly known as green-veined shell orchid, is a species of orchid endemic to the south-west of Western Australia. As with similar orchids, the flowering plants differ from those which are not flowering. The non-flowering plants have a rosette of leaves but the flowering plants lack a rosette and have a single flower with leaves on the flowering spike. This greenhood has a white flower with green and pale brownish-fawn stripes and a long, curved protruding labellum. It is found in inland areas between Kalbarri and Esperance.
