It has a single thin leaf fused to the flowering stem and up to fifteen small, yellowish green flowers with a reddish labellum. The flowers do not open widely and are self-pollinating. It grows in heath and shallow moss gardens on rock ledges from the Blue Mountains to Nerriga. DescriptionGenoplesium apostasioides is a terrestrial, perennial, deciduous, herb with an underground tuber and a single thin leaf {{convert|150-300|mm|in|sigfig=1|abbr=on}} long and fused to the flowering stem with the free part {{convert|15-25|mm|in|sigfig=1|abbr=on}} long. Between three and fifteen yellowish-green flowers are widely spaced along a flowering stem {{convert|20-40|mm|in|sigfig=1|abbr=on}} tall and much taller than the leaf. The flowers are {{convert|4-5.5|mm|in|sigfig=1|abbr=on}} long and open erratically, or do not open at all and are self-pollinating. As with others in the genus, the flowers are inverted so that the labellum is above the column rather than below it. The dorsal sepal is lance-shaped to egg-shaped, about {{convert|5|mm|in|sigfig=2|abbr=on}} long and {{convert|2.5|mm|in|sigfig=1|abbr=on}} wide with hairy edges. The lateral sepals are linear to lance-shaped, about {{convert|6.5|mm|in|sigfig=1|abbr=on}} long, {{convert|2|mm|in|sigfig=1|abbr=on}} wide, more or less parallel to each other and sometimes have a gland on the tip. The petals are lance-shaped to egg-shaped, about {{convert|4|mm|in|sigfig=1|abbr=on}} long, {{convert|1.5|mm|in|sigfig=1|abbr=on}} wide with hairy edges and a sharply pointed tip. The labellum is reddish, about {{convert|7.5|mm|in|sigfig=1|abbr=on}} long, {{convert|2|mm|in|sigfig=1|abbr=on}} wide, with hairy edges and a sharply pointed tip. There is a callus in the centre of the labellum and extending nearly to its tip. Flowering occurs from December to April.[2][3]Taxonomy and namingThe freak midge orchid was first formally described in 1888 by Robert D. FitzGerald who gave it the name Corunastylis apostasioides from a specimen collected near Berrima, and published the description in his book Australian Orchids.[4] In 1989, David Jones and Mark Alwin Clements changed the name to Genoplesium apostasioides.[5] Distribution and habitatGenoplesium apostasioides grows in forest and in moss gardens on rock shelves, on the tablelands between the Blue Mountains and Nerriga.[2][3]References1. ^{{WCSP | 89158 | Genoplesium apostasioides}} 2. ^1 {{cite book|last1=Jones|first1=David L.|title=A complete guide to native orchids of Australia including the island territories|date=2006|publisher=New Holland|location=Frenchs Forest, N.S.W.|isbn=1877069124|page =176}} 3. ^1 {{cite web|last1=Jones|first1=David L.|title=Genoplesium anthracinum|url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Genoplesium~apostasioides|publisher=Royal Botanic Garden Sydney|accessdate=28 January 2018}} 4. ^{{cite web|title=Corunastylis apostasioides|url= https://id.biodiversity.org.au/instance/apni/498151|publisher=APNI|accessdate=28 January 2018}} 5. ^{{cite web|title=Genoplesium apostasioides|url= https://id.biodiversity.org.au/instance/apni/473667|publisher=APNI|accessdate=28 January 2018}} External links
