About

Pterostylis glebosa, commonly known as the clubbed snail orchid, is a species of orchid endemic to the south-west of Western Australia. Non-flowering plants have a rosette of leaves flat on the ground but flowering plants usually lack a rosette and have a single green and white flower with club-like lateral sepals. It sometimes forms colonies of thousands of plants.

Where it grows

The clubbed snail orchid usually grows in swampy places, often amongst sedges and under Melaleuca species, sometimes with part of its flowering stem in shallow water. It occurs between Eneabba and Manjimup in the Jarrah Forest and Swan Coastal Plain biogeographic regions.
