It has a single relatively large, erect, fleshy, channelled leaf and up to thirteen deep blue, self-pollinating flowers. DescriptionThelymitra adorata is a tuberous, perennial herb with a single erect, dark green, fleshy, channelled, linear leaf {{convert|140-400|mm|in|sigfig=1|abbr=on}} long and {{convert|5-20|mm|in|sigfig=1|abbr=on}} wide with a purplish base. Up to eighteen deep blue flowers {{convert|14-22|mm|in|sigfig=1|abbr=on}} wide are arranged on a flowering stem {{convert|250-650|mm|in|sigfig=1|abbr=on}} tall. The sepals and petals are {{convert|6-12|mm|in|sigfig=1|abbr=on}} long, {{convert|3-6.5|mm|in|sigfig=1|abbr=on}} wide and light brown on their reverse side. The column is pink or purplish, {{convert|4.5-6.5|mm|in|sigfig=2|abbr=on}} long and {{convert|2.5-4|mm|in|sigfig=1|abbr=on}} wide. The lobe on the top of the anther is dark brown to blackish with a yellow tip, tubular and sharply curved with a notched tip. The side lobes curve upwards and have untidy, mop-like tufts of white hairs. Flowering occurs from September to November but the flowers are self-pollinating and only open on sunny days.[2][3][4]Taxonomy and namingThelymitra adorata was first formally described in 2011 by Jeff Jeanes and the description was published in Muelleria from a specimen collected near Wadalba.[5] The specific epithet (adorata) is a Latin word meaning "honor", "esteem" or "worship",[6] referring to the column which, in side view, "has been likened to a person in prayer".[4]Distribution and habitatThe Wyong sun orchid usually grows in grassy woodland in very small isolated colonies between Wyong, Warnervale and Wyongah.[2][3][7][8] ConservationThelymitra adorata only occurs in a small number of isolated sites and is threatened by weed invasion, habitat fragmentation and disturbance and inappropriate management activities. It is listed as "critically endangered" under the under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and under the New South Wales Government NSW Threatened Species Conservation Act.[2][7][8]References1. ^{{WCSP | 465987 | Thelymitra adorata }} 2. ^1 2 3 {{cite web|title=Conservation advice - Thelymitra adorata|url=http://www.environment.gov.au/biodiversity/threatened/species/pubs/84724-conservation-advice.pdf|publisher=Australian Government Department of the Environment|accessdate=23 May 2018}} 3. ^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 =238}} 4. ^1 {{cite journal|last1=Jeanes|first1=Jeffrey A.|title=Resolution of the Thelymitra aristata (Orchidaceae) complex of south-eastern Australiaa|journal=Muelleria|date=2004|volume=19|pages=50–52|url=https://www.rbg.vic.gov.au/documents/Muelleria_29%282%29%2C_pp110-129_-_Jeanes.pdf|accessdate=21 May 2018}} 5. ^{{cite web|title=Thelymitra adorata|url= https://id.biodiversity.org.au/instance/apni/707494|publisher=APNI|accessdate=23 May 2018}} 6. ^{{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.|page=418}} 7. ^1 {{cite web|title=Thelymitra sp.
