A terrestrial orchid with a slender flowering stem to 40 cm with up to 5 closely sheathing stem leaves. Leave are elliptic to ovate, up to 3.5 cm long and 15 mm wide. Up to 8 leaves form the basal rosette that slightly ascends the stem. The 4 - 10 (12) flowers are 1.5 cm long, semi-erect, transparent with red-brown suffusions.


Recorded in Queensland and NSW. In NSW it is currently known from 18 scattered locations in a relatively small area between Taree and Kurri Kurri, extending to the south-east towards Tea Gardens and west into the Upper Hunter, with additional records near Denman and Wingen. There are also isolated records from the Sydney region. The species occurs in two conservation reserves, Columbey National Park and Wingen Maid Nature Reserve.

Habitat and ecology

  • The preferred habitat is seasonally moist, dry sclerophyll forest with a grass and shrub understorey.
  • The most commonly observed habitat is vegetation characterised by grassy open forests or derived native grasslands of Eucalyptus amplifolia and Eucalyptus moluccana on gentle flats, or that are dominated by Corymbia maculata with any of Eucalyptus fibrosa, Eucalyptus sideroploia or Eucalyptus crebra.
  • Flowers from September to November. Vegetative reproduction is not common in this group of Greenhoods, but some species may form more than one dropper annually. Fails to flower in dry seasons.
  • Plants are deciduous and die back to the large, underground tubers after seed release. New rosettes are produced following soaking autumn and winter rains.
  • Flowers are pollinated by fungus gnats (family Keroplatidae).
