Pterostylis dilatata (original) (raw)

Pterostylis dilatata, commonly known as the robust snail orchid, is a species of orchid which is endemic to the south-west of Western Australia. Non-flowering plants have a rosette of leaves but flowering plants lack a rosette and have a single green and white flower on a flowering stem with stem leaves. The flowers appear in winter and have lateral sepals which almost close off the front of the flower.
