}} Caladenia applanata subsp. erubescens, commonly known as the rose 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 uniformly pink, sweet-smelling flowers which have a broad, flattened labellum. DescriptionCaladenia applanata subsp. erubescens is a terrestrial, perennial, deciduous, herb with an underground tuber and a single, broad, hairy leaf, {{convert|120-200|mm|in|sigfig=1|abbr=on}} long and {{convert|5-10|mm|in|sigfig=1|abbr=on}} wide. Up to three pink, sweetish-smelling flowers {{convert|80-100|mm|in|sigfig=1|abbr=on}} long and {{convert|60-80|mm|in|sigfig=1|abbr=on}} wide are borne on a stalk {{convert|250-400|mm|in|sigfig=1|abbr=on}} tall. The sepals have narrow, light brown, club-like glandular tips. The dorsal sepal is erect and the lateral sepals and petals spread stiffly near their bases, then turn downwards. The labellum is pink, {{convert|20-23|mm|in|sigfig=1|abbr=on}} long, {{convert|11-15|mm|in|sigfig=1|abbr=on}} wide, the sides 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 along its centre. Flowering occurs from September to late October. This subspecies differs from subspecies applanata in having pink flowers.[1][2][3]Taxonomy and namingCaladenia erubescens was first formally described in 2001 by Stephen Hopper and Andrew Phillip Brown. Hopper and Brown described two subspecies including Caladenia applanata subsp. erubescens and the description was published in Nuytsia.[4] The subspecies name ("erubescens") is a Latin word meaning "growing red", "redden" or "blush",[5] referring to the pink colour of the flowers of this orchid.[2]Distribution and habitatThe rose spider orchid grows in low heath in coastal areas between William Bay and Albany in the Warren biogeographic region.[1][2][3][6] ConservationCaladenia applanata subsp. erubescens 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|pages =66–67}} {{Taxonbar|from=Q26202439}}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=124|edition=3rd}} 4. ^1 {{cite web|title=Caladenia applanata subsp. erubescens|url= https://id.biodiversity.org.au/instance/apni/573807|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 =651}} 6. ^1 {{FloraBase|name=Caladenia applanata subsp. erubescens|id=15329}} 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 |
