It has two broad leaves and a single greenish brown flower with a callus of many glands covering most of the top of the labellum. DescriptionChiloglottis platyptera is a terrestrial, perennial, deciduous, herb with two elliptic to oblong leaves {{convert|40-75|mm|in|sigfig=1|abbr=on}} long and {{convert|14-22|mm|in|sigfig=1|abbr=on}} wide on a petiole {{convert|3-8|mm|in|sigfig=1|abbr=on}} long. A single greenish brown flower {{convert|10-12|mm|in|sigfig=1|abbr=on}} long and {{convert|8-9|mm|in|sigfig=2|abbr=on}} wide is borne on a flowering stem {{convert|50-100|mm|in|sigfig=1|abbr=on}} high. The dorsal sepal is spatula-shaped, more or less erect, about {{convert|13|mm|in|sigfig=1|abbr=on}} long and {{convert|3|mm|in|sigfig=1|abbr=on}} wide. The lateral sepals are linear, {{convert|7-10|mm|in|sigfig=1|abbr=on}} long, about {{convert|1|mm|in|sigfig=1|abbr=on}} wide, spread apart from each other and curve downwards. There is a glandular tip less than {{convert|1|mm|in|sigfig=1|abbr=on}} long on all three sepals. The petals are lance-shaped with the narrower end towards the base, about {{convert|10|mm|in|sigfig=1|abbr=on}} long, {{convert|3|mm|in|sigfig=1|abbr=on}} wide, slightly curved and turned down against the sides of the ovary. The labellum is shaped like a bricklayer's trowel with the narrower end towards the base. It is {{convert|9-10|mm|in|sigfig=2|abbr=on}} long, about {{convert|8|mm|in|sigfig=1|abbr=on}} wide and most of the upper surface of the labellum is covered with a callus of many short reddish, yellowish, bright green or black glands, the one nearest the base of the labellum about {{convert|1.5|mm|in|sigfig=1|abbr=on}} long and shaped like handlebars. The column is pale green with purple streaks, about {{convert|9|mm|in|sigfig=1|abbr=on}} long, {{convert|6|mm|in|sigfig=1|abbr=on}} wide with broad wings. Flowering occurs from September to November.[2][3][4][5]Taxonomy and namingChiloglottis platyptera was first formally described in 1991 by David Jones from a specimen collected in Barrington Tops National Park and the description was published in Australian Orchid Research.[6] The specific epithet (platyptera) is derived from the Ancient Greek words platys meaning "broad, wide, flat (or) level"[7]{{rp|474}} and pteron meaning "feather" or "wing",[7]{{rp|859}} referring to the brown wings on the column of this orchid.[4]Distribution and habitatThe winged ant orchid grows with grass in tall forest and on the edges of rainforest between Dungog and Yarrowitch, including in the Barrington Tops, Oxley Wild Rivers and Ben Halls Gap National Parks.[2][3] ConservationChiloglottis platyptera is listed as "vulnerable" under the New South Wales Government Biodiversity Conservation Act 2016. The main threats to the species are grazing by domestic stock, weed invasion (especially by scotch broom), the activities of feral pigs and land clearing.[8][3]References1. ^1 {{WCSP | 38980 | Chiloglottis platyptera }} 2. ^1 2 {{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 =142}} 3. ^1 2 {{cite web|title=Chiloglottis platyptera (a terrestrial orchid) - vulnerable species listing|url=http://www.environment.nsw.gov.au/determinations/ChiloglottisPlatypteraVulSpListing.htm|publisher=New South Wales Government Office of Environment and Heritage|accessdate=21 April 2018}} 4. ^1 {{cite journal|last1=Jones|first1=David L.|title=New taxa of Australian Orchidaceae|journal=Australian Orchid Research|date=1991|volume=2|pages=39–40}} 5. ^{{cite web|last1=Jones|first1=David L.|title=Chiloglottis platyptera|url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Chiloglottis~platyptera|publisher=Royal Botanic Garden Sydney|accessdate=21 April 2018}} 6. ^{{cite web|title=Chiloglottis platyptera|url= https://id.biodiversity.org.au/instance/apni/551598|publisher=APNI|accessdate=21 April 2018}} 7. ^1 {{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.}} 8. ^1 {{cite web|title=Barrington Tops Ant Orchid - profile|url=http://www.environment.nsw.gov.au/threatenedSpeciesApp/profile.aspx?id=10165|publisher=New South Wales Government Office of Environment and Heritage|accessdate=21 April 2018}} External links
