It has a single thin leaf fused to the flowering stem and up to twenty small reddish-brown to dark purplish flowers. It is known from one population with only six plants in forest near a swamp. DescriptionCorunastylis leptochila is a terrestrial, perennial, deciduous, herb with an underground tuber and a single thin leaf {{convert|100-150|mm|in|sigfig=1|abbr=on}} long. Between five and twenty reddish-brown to dark purplish flowers are densely crowded along a flowering stem {{convert|8-15|mm|in|sigfig=1|abbr=on}} tall. The flowers lean downward and are {{convert|4-5|mm|in|sigfig=2|abbr=on}} wide. The flowers and are inverted so that the labellum is above the column rather than below it. The dorsal sepal is egg-shaped, {{convert|2-2.5|mm|in|sigfig=1|abbr=on}} long and about {{convert|1.5|mm|in|sigfig=1|abbr=on}} wide. The lateral sepals are linear to lance-shaped, {{convert|3.5-4.5|mm|in|sigfig=1|abbr=on}} long, {{convert|1|mm|in|sigfig=1|abbr=on}} wide with a small white gland on the tip. The petals are egg-shaped, about {{convert|2.5|mm|in|sigfig=1|abbr=on}} long and {{convert|1|mm|in|sigfig=1|abbr=on}} wide and also have a small gland on the tip. The labellum is narrow elliptic to narrow oblong, about {{convert|2|mm|in|sigfig=1|abbr=on}} long and {{convert|1|mm|in|sigfig=1|abbr=on}} wide. There is an oblong callus in the centre of the labellum and extending nearly to its tip. Flowering occurs in November and December.[1]Taxonomy and namingCorunastylis leptochila was first formally described in 2017 by David Jones from a specimen collected near Lavers Hill and the description was published in Australian Orchid Research.[2] The specific epithet (leptochila) is derived from the Ancient Greek words leptos meaning "fine" or "small"[3]{{rp|488}} and cheilos meaning "lip" or "rim".[3]{{rp|486}} Distribution and habitatCorunastylis leptochila grows in forest near a swamp near Lavers Hill where only six plants are known.[1]References1. ^1 {{cite web|last1=Jeanes|first1=Jeff|title=Corunastylis leptochila|url=https://vicflora.rbg.vic.gov.au/flora/taxon/43f2910c-5d59-481c-96cf-f07f96dac704|publisher=Royal Botanic Gardens Victoria|accessdate=16 February 2018}} 2. ^1 {{cite web|title=Corunastylis leptochila|url= https://id.biodiversity.org.au/instance/apni/9608781|publisher=APNI|accessdate=16 February 2018}} 3. ^1 {{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.}} External links
