It has a single long, curved leaf and up to seven or more white to pale blue flowers, green on their back side. DescriptionThelymitra aggericola is a tuberous, perennial herb with a single curved, linear to lance-shaped leaf {{convert|70-150|mm|in|sigfig=1|abbr=on}} long, {{convert|4-10|mm|in|sigfig=1|abbr=on}} wide and often as long as, or longer than the flowering stem. Up to seven or more white to pale blue flowers {{convert|24-48|mm|in|sigfig=1|abbr=on}} wide are arranged on a flowering stem {{convert|50-140|mm|in|sigfig=1|abbr=on}} tall. The sepals and petals are {{convert|8-13|mm|in|sigfig=1|abbr=on}} long, {{convert|3.5-4.5|mm|in|sigfig=1|abbr=on}} wide and green on the reverse side. The column is white, {{convert|5-6|mm|in|sigfig=2|abbr=on}} long and about {{convert|2.5|mm|in|sigfig=1|abbr=on}} wide. The lobe on the top of the anther is pale yellow to light brown, sharply curved with an inflated hood. The side lobes have dense, mop-like tufts of white hairs. Flowering occurs in October and November.[2][3]Taxonomy and namingThelymitra aggericola was first formally described in 1999 by David Jones from a specimen collected near Temma south of Arthur River and the description was published in The Orchadian.[4] The specific epithet (aggericola) is derived from the Latin words agger meaning "heap" or "mound" [5]{{rp|401}} and -cola meaning "dweller".[5]{{rp|217}} Distribution and habitatThe bleak sun orchid usually grows in rock crevices and shallow soil pockets close to the coast in the north-west and south-east of Tasmania. The plants open freely on warm to hot days and many seed capsules are produced, suggesting that the flowers are capable of self pollination.[2][3] References1. ^{{WCSP | 203709 | Thelymitra aggericola }} 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|pages =228–229}} 3. ^1 {{cite journal|last1=Jeanes|first1=Jeffrey A.|title=An overview of the Thelymitra nuda (Orchidaceae) complex in Australia including the description of six new species|journal=Muelleria|date=2013|volume=31|page=9|url=https://www.rbg.vic.gov.au/documents/MuelleriaVol-31-p3-Jeanes-PDF-Accessibility.pdf|accessdate=11 May 2018}} 4. ^{{cite web|title=Thelymitra aggericola|url= https://id.biodiversity.org.au/instance/apni/581271|publisher=APNI|accessdate=11 May 2018}} 5. ^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
