Chiloglottis gunnii, commonly known as the tall bird orchid, is a species of orchid endemic to Tasmania. It has two broad leaves and a single green to purplish brown flower with a line of erect calli with swollen heads along the mid-line of the labellum. It is widespread but mainly in coastal districts and most commonly in moist to wet forest.
Description
Chiloglottis gunnii is a terrestrial, perennial, deciduous, herb with two leaves {{convert|40-60|mm|in|sigfig=2|abbr=on}} long and {{convert|15-20|mm|in|sigfig=1|abbr=on}} wide. A single green to purplish brown flower {{convert|20-24|mm|in|sigfig=2|abbr=on}} long and {{convert|20-25|mm|in|sigfig=1|abbr=on}} wide is borne on a flowering stem {{convert|60-100|mm|in|sigfig=1|abbr=on}} high. The dorsal sepal is egg-shaped to spatula-shaped with the narrower end towards the base, {{convert|20-24|mm|in|sigfig=1|abbr=on}} long and {{convert|7-11|mm|in|sigfig=1|abbr=on}} wide. The lateral sepals are linear to lance-shaped, {{convert|15-20|mm|in|sigfig=1|abbr=on}} long, about {{convert|2|mm|in|sigfig=1|abbr=on}} wide and taper towards their tips. There is a glandular tip {{convert|0.5-1.5|mm|in|sigfig=1|abbr=on}} long on the end of all three sepals. The petals are lance-shaped but curved, {{convert|15-17|mm|in|sigfig=1|abbr=on}} long, {{convert|4.5-6|mm|in|sigfig=2|abbr=on}} wide and spread widely apart from each other. The labellum is broadly egg-shaped to heart-shaped, {{convert|10-13|mm|in|sigfig=1|abbr=on}} long and {{convert|10-15|mm|in|sigfig=1|abbr=on}} wide with a line of pillar-like calli about {{convert|3|mm|in|sigfig=1|abbr=on}} high with large swollen heads up to {{convert|2|mm|in|sigfig=1|abbr=on}} wide. The column is {{convert|15-18|mm|in|sigfig=1|abbr=on}} long and {{convert|5-6|mm|in|sigfig=2|abbr=on}} wide and curved with narrow wings.{{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 =144}}{{cite journal|last1=Jones|first1=David L.|title=Contributions to Tasmanian Orchidology|journal=Australian Orchid Research|date=1998|volume=3|pages=64–65}}
Taxonomy and naming
Chiloglottis gunnii was first formally described in 1840 by John Lindley and the description was published in his book The Genera and Species of Orchidaceous Plants.{{cite web|title=Chiloglottis gunnii|url= https://id.biodiversity.org.au/instance/apni/471569|publisher=APNI|accessdate=20 April 2018}}{{cite book|last1=Lindley|first1=John|title=The Genera and Species of Orchidaceous Plants|date=1840|publisher=Ridgways|location=London|page=387|url=https://www.biodiversitylibrary.org/item/9889#page/399/mode/1up|accessdate=21 April 2018}} The specific epithet (gunnii) honours Ronald Campbell Gunn, who collected the type specimen which was sent to William Jackson Hooker who forwarded it to Lindley.{{cite web|title=Gunn, Ronald Campbell (1808 - 1881)|url=http://www.anbg.gov.au/biography/gunn-ronald.html|publisher=Australian National Botanic Garden|accessdate=21 April 2018}}
