Pterostylis karri, commonly known as the karri snail orchid, is a species of orchid endemic to the south-west of Western Australia. Both flowering and non-flowering plants usually have a small rosette of leaves and flowering plants have a single green and white flower with unusually long, erect lateral sepals. Like some similar greenhoods, it often forms dense colonies.
