Pterostylis valida is a distinctive orchid with small underground tubers. The species is recognised by its stout appearance and large greenish flowers that have narrow, curved lateral sepals with sparsely hairy margins. The leaves are either broad and clustered in a basal rosette or narrow and stem-clasping. There are four to eight oval-shaped leaves, approximately 2 cm long and 1.2 cm wide, with short leaf-stalks. The leaves are sometimes absent at the flowering stage.
