Pterostylis fischii, commonly known as Fisch's greenhood, is a species of orchid endemic to south-eastern Australia. As with similar greenhoods, the flowering plants differ from those which are not flowering. The non-flowering plants have a rosette of leaves flat on the ground but the flowering plants have a single flower with leaves on the flowering spike. This greenhood has tawny-coloured flowers, a dorsal sepal with a long thread-like tip and a labellum which is hidden inside the flower.
