Prasophyllum stygium

Prasophyllum stygium, commonly known as the elfin leek orchid, is a species of orchid endemic to Victoria. It has a single tube-shaped leaf and up to twenty greenish-brown flowers with a white labellum. It is a recently described plant, previously included with P. fitzgeraldii, but distinguished from that species by its greenish-brown flowers with their white labellum and narrower brown callus. It is only known from a single population of about thirty plants.
