}} Caladenia remota subsp. parva, commonly known as the Perenjori spider orchid, is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It has a single hairy leaf and up to three creamy-white to pale yellow flowers. It has a more restricted and more westerly distribution than subspecies remota. DescriptionCaladenia remota subsp. parva is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, {{convert|150-170|mm|in|sigfig=1|abbr=on}} long and {{convert|5-7|mm|in|sigfig=1|abbr=on}} wide. Up to three cream-coloured to creamy-yellow flowers {{convert|50-80|mm|in|sigfig=1|abbr=on}} long and {{convert|40-60|mm|in|sigfig=2|abbr=on}} wide are borne on a spike {{convert|140-200|mm|in|sigfig=1|abbr=on}} tall. The sepals and petals have long, brown, thread-like tips. The dorsal sepal is erect and the lateral sepals spread apart and turned downwards. The petals spread horizontally near their bases but then turn downwards. The labellum is {{convert|9-14|mm|in|sigfig=1|abbr=on}} long, {{convert|8-10|mm|in|sigfig=1|abbr=on}} wide and cream coloured with red lines and marks. The sides of the labellum have many short blunt teeth, the tip curls under and there are two rows of anvil-shaped, white calli, sometimes with red tips, along its centre. Flowering occurs from August to mid-September.[1][2][3]Taxonomy and namingCaladenia remota was first described in 2001 by Stephen Hopper and Andrew Phillip Brown and the description was published in Nuytsia. At the same time they described two subspecies, including subspecies parva.[4] The subspecies name (parva) is a Latin word meaning "little"[5] referring to the smaller size of this subspecies compared to subspecies remota.[2]Distribution and habitatThe Perenjori spider orchid is found between Perenjori and Wubin in the Avon Wheatbelt and Yalgoo biogeographic regions where it usually grows in shrublands that are wet in winter.[1][2][3][6] ConservationCaladenia remota subsp. parva 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 =109}} {{Taxonbar|from=Q26214087}}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=71}} 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=46|edition=3rd}} 4. ^1 2 {{cite web|title=Caladenia remota subsp. parva|url=https://id.biodiversity.org.au/instance/apni/574449|publisher=APNI|accessdate=9 March 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 =489}} 6. ^1 {{FloraBase|name=Caladenia remota subsp. parva|id=18029}} 6 : Caladenia|Endemic orchids of Australia|Orchids of Western Australia|Plants described in 2001|Taxa named by Stephen Hopper|Taxa named by Andrew Phillip Brown |
