}} Caladenia thinicola, commonly known as the Scott River spider orchid, is a species of orchid endemic to the south-west of Western Australia. It has a single erect, hairy leaf and up to four yellowish-green and red flowers with a fringe of long teeth on the sides of the labellum and thick brown, club-like glandular tips on the sepals. DescriptionCaladenia thinicola is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, 130–260 mm long and 5–7 mm wide. Up to four yellowish-green flowers with red markings and 70–90 mm long and 50–70 mm wide are borne on a stalk 450–500 mm tall. The sepals have thick brown, club-like glandular tips. The dorsal sepal is erect, about 40 mm long and 2 mm wide. The lateral sepals are 40 mm long and 3 mm wide, spread apart from each other and turned downwards. The petals are about 35 mm long and 2 mm wide and curve downwards. The labellum is 15–16 mm long, 12–13 mm wide and yellowish green with a dark red tip which curls downwards. The sides of the labellum have thin greenish teeth up to 8 mm long and there are four crowded rows of dark red calli up to 1.5 mm long, along the mid-line of the labellum. Flowering occurs from September to November.[1][2][3]Taxonomy and namingCaladenia thinicola was first formally described in 2001 by Stephen Hopper and Andrew Phillip Brown from a specimen collected near Pemberton and the description was published in Nuytsia.[4] The specific epithet (thinicola) is derived from the Ancient Greek word thinos meaning "beach", "shore" or "sand heap"[5]{{rp|707}} and the Latin suffix -cola meaning "dweller in"[5]{{rp|48}} referring to the sand dunes where this species is often found.[2]Distribution and habitatThe Scott River spider orchid is found between Cape Naturaliste and the Warren River in the Jarrah Forest, Swan Coastal Plain and Warren biogeographic regions where it grows in deep sand in woodland in coastal areas.[1][2][3][6] ConservationCaladenia thinicola is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[6]References1. ^1 {{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 =84}} {{Taxonbar|from=Q9674005}}2. ^1 2 {{cite book|last1=Brown|first1=Andrew|last2=Dundas|first2=Pat|last3=Dixon|first3=Kingsley|last4=Hopper|first4=Stephen|title=Orchids of Western Australia|date=2008|publisher=University of Western Australia Press|location=Crawley, Western Australia|isbn=9780980296457|page=107}} 3. ^1 {{cite book|last1=Hoffman|first1=Noel|last2=Brown|first2=Andrew|title=Orchids of South-West Australia|date=2011|publisher=Noel Hoffman|location=Gooseberry Hill|isbn=9780646562322|page=133|edition=3rd}} 4. ^1 {{cite web|title=Caladenia thinicola|url=https://id.biodiversity.org.au/instance/apni/574134|publisher=APNI|accessdate=22 March 2017}} 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.}} 6. ^1 {{FloraBase|name=Caladenia thinicola|id=18040}} 7 : Caladenia|Endemic orchids of Australia|Orchids of Western Australia|Plants described in 2001|Endemic flora of Western Australia|Taxa named by Stephen Hopper|Taxa named by Andrew Phillip Brown |
