Description
Chiloglottis sylvestris is a terrestrial, perennial, deciduous, herb with two leaves {{convert|30-60|mm|in|sigfig=1|abbr=on}} long and {{convert|12-20|mm|in|sigfig=1|abbr=on}} wide. A single greenish pink flower {{convert|20-26|mm|in|sigfig=1|abbr=on}} long and {{convert|5-6|mm|in|sigfig=2|abbr=on}} wide is borne on a flowering stem {{convert|30-50|mm|in|sigfig=1|abbr=on}} high. The dorsal sepal is linear to spatula-shaped, {{convert|10-13|mm|in|sigfig=1|abbr=on}} long and {{convert|2-2.5|mm|in|sigfig=1|abbr=on}} wide. The lateral sepals are linear, {{convert|10-14|mm|in|sigfig=1|abbr=on}} long, about {{convert|0.5|mm|in|sigfig=1|abbr=on}} wide and curve downwards and away from each other. There is a glandular tip {{convert|2-3|mm|in|sigfig=1|abbr=on}} long on all three sepals. The petals are lance-shaped, {{convert|7-10|mm|in|sigfig=1|abbr=on}} long, about {{convert|2|mm|in|sigfig=1|abbr=on}} wide and turn downwards towards the ovary. The labellum is diamond-shaped, {{convert|7-10|mm|in|sigfig=1|abbr=on}} long and {{convert|5-6|mm|in|sigfig=2|abbr=on}} wide. There is a reddish black, insect-like callus covering about two-thirds of the middle of the base of the labellum. This large callus is surrounded by many fine, radiating, reddish, club-shaped calli and smaller red calli. The column has narrow wings. Flowering occurs from December to May.{{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|pages =140–141}}{{cite web|last1=Jones|first1=David L.|title=Chiloglottis sylvestris|url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Chiloglottis~sylvestris|publisher=Royal Botanic Garden Sydney|accessdate=23 April 2018}}{{cite book|last1=Bishop|first1=Tony|title=Field guide to the orchids of New South Wales and Victoria|date=2000|publisher=UNSW Press|location=Sydney|isbn=0868407062|page=120|edition=2nd}}
