}} Caladenia applanata subsp. applanata, commonly known as the broad-lipped spider orchid, is a species of orchid endemic to the south-west of Western Australia. It is a relatively common orchid with a single erect, hairy leaf and up to three flowers which may be red, cream, green or yellow and have a broad, flattened, red-tipped labellum. DescriptionCaladenia applanata subsp. applanata is a terrestrial, perennial, deciduous, herb with an underground tuber and a single, broad, hairy leaf, {{convert|90-200|mm|in|sigfig=1|abbr=on}} long and {{convert|4-10|mm|in|sigfig=1|abbr=on}} wide. Up to three (rarely four) flowers {{convert|70-90|mm|in|sigfig=1|abbr=on}} long and {{convert|60-80|mm|in|sigfig=1|abbr=on}} wide are borne on a stalk {{convert|250-500|mm|in|sigfig=1|abbr=on}} tall. The sepals have narrow, light brown, club-like glandular tips. The dorsal sepal is erect, {{convert|40-80|mm|in|sigfig=1|abbr=on}} long, {{convert|2.5-3.5|mm|in|sigfig=1|abbr=on}} wide and the lateral sepals are {{convert|40-80|mm|in|sigfig=1|abbr=on}} long, {{convert|3-6|mm|in|sigfig=1|abbr=on}} wide and spread stiffly near their bases, then turn downwards. The petals are {{convert|30-50|mm|in|sigfig=1|abbr=on}} long and {{convert|2-4|mm|in|sigfig=1|abbr=on}} wide and arranged like the lateral sepals. The labellum is {{convert|20-23|mm|in|sigfig=1|abbr=on}} long and {{convert|11-15|mm|in|sigfig=1|abbr=on}} wide with a dark maroon tip. The sides of the labellum have many spreading teeth up to {{convert|4|mm|in|sigfig=1|abbr=on}} long and there are four or more rows of crowded, deep red calli up to {{convert|3|mm|in|sigfig=1|abbr=on}} long along its centre. Flowering occurs from September to late October. This subspecies differs from subspecies erubescens which has pink flowers.[1][2][3]Taxonomy and namingCaladenia applanata was first formally described in 2001, Stephen Hopper and Andrew Phillip Brown. Hopper and Brown described two subspecies including the autonym Caladenia applanata subsp. applanata and the description was published in Nuytsia.[4] The specific epithet ("applanata") is a Latin word meaning "flattened",[5] referring to the broad labellum.[2]Distribution and habitatThe broad-lipped spider orchid is found in low heath, often over limestone, in coastal areas between Yallingup and Albany in the Jarrah Forest and Warren biogeographic regions[1][2][3][6] ConservationCaladenia applanata subsp. applanata 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=66}} {{Taxonbar|from=Q26202438}}2. ^1 2 {{cite book|last1=Brown|first1=Andrew|last2=Dixon|first2=Kingsley|last3=French|first3=Christopher|last4=Brockman|first4=Garry|title=Field guide to the orchids of Western Australia : the definitive guide to the native orchids of Western Australia|date=2013|publisher=Simon Nevill Publications|isbn=9780980348149|page=98}} 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=123|edition=3rd}} 4. ^1 2 {{cite web|title=Caladenia applanata subsp. applanata|url= https://id.biodiversity.org.au/instance/apni/573806|publisher=APNI|accessdate=16 February 2017}} 5. ^{{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.|page =97}} 6. ^1 {{FloraBase|name=Caladenia applanata subsp. applanata|id=15328}} 6 : Caladenia|Orchids of Western Australia|Endemic orchids of Australia|Plants described in 2001|Taxa named by Stephen Hopper|Taxa named by Andrew Phillip Brown |
