}} Caladenia patersonii is a plant in the orchid family Orchidaceae and is native to Victoria and Tasmania. It is a ground orchid with a single hairy leaf and one or two creamy-white, yellowish or pink flowers. DescriptionCaladenia patersonii is a terrestrial, perennial, deciduous, herb with an underground tuber and a single densely hairy leaf, {{convert|80-150|mm|in|sigfig=1|abbr=on}} long, {{convert|10-15|mm|in|sigfig=1|abbr=on}} wide. The leaf often has red to purple blotches near its base. One or two creamy-white, yellowish or pink flowers with dark red lines are borne on a spike {{convert|250-350|mm|in|sigfig=2|abbr=on}} tall. The sepals and petals have brown or reddish-brown, densely glandular, thread-like tips. The dorsal sepal is erect, {{convert|60-80|mm|in|sigfig=1|abbr=on}} long and {{convert|2-4|mm|in|sigfig=1|abbr=on}} wide. The lateral sepals are {{convert|60-80|mm|in|sigfig=1|abbr=on}} long, {{convert|3-6|mm|in|sigfig=1|abbr=on}} wide, spread widely and downturned with drooping ends. The petals are {{convert|40-60|mm|in|sigfig=2|abbr=on}} long, {{convert|3-4|mm|in|sigfig=1|abbr=on}} wide and arranged like the lateral sepals. The labellum is {{convert|12-20|mm|in|sigfig=1|abbr=on}} long, {{convert|7-11|mm|in|sigfig=1|abbr=on}} wide and white to cream-coloured, often with a dark red tip. The sides of the labellum have many reddish teeth up to {{convert|2|mm|in|sigfig=1|abbr=on}} long and the tip is curled under. There are four or six rows of reddish calli up to {{convert|1.5|mm|in|sigfig=1|abbr=on}} long in the centre of the labellum. Flowering occurs from September to November and is more prolific after fire.[1][2][3][4]Taxonomy and namingCaladenia patersonii was first formally described in 1810 by Robert Brown and the description was published in ''Prodromus florae Novae Hollandiae.[5][6]Distribution and habitatPaterson's spider orchid is found mostly in eastern coastal Victoria and northern Tasmania where it grows in heath and heathy woodland.[1][2][3][4] ConservationCaladenia patersonii is listed as "vulnerable" in Tasmania under the Threatened Species Protection Act 1995.[1]References1. ^1 2 {{cite web|last1=Jeanes|first1=Jeffrey|title=Caladenia patersonii|url=https://vicflora.rbg.vic.gov.au/flora/taxon/6b02f3e0-36ce-4ea2-8374-c3062c6e9e98|publisher=Royal Botanic Gardens Victoria: Vicflora|accessdate=1 March 2017}} {{Taxonbar|from=Q15287664}}{{DEFAULTSORT:Caladenia patersonii}}2. ^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 =58}} 3. ^1 {{cite journal|last1=Jones|first1=David L.|title=Contributions to Tasmanian Orchidology - 1|journal=Australian Orchid Research|date=1998|volume=3|pages=37–38}} 4. ^1 {{cite web|title=Threatened Species Listing Statement - Caladenia patersonii|url=http://dpipwe.tas.gov.au/Documents/Caladenia-patersonii-listing-statement.pdf|publisher=Tasmanian Government Department of Primary Industries, Parks, Water and Environment|accessdate=1 March 2017}} 5. ^1 2 {{cite web|title=Caladenia patersonii|url= https://id.biodiversity.org.au/instance/apni/514489|publisher=APNI|accessdate=1 March 2017}} 6. ^{{cite book|last1=Brown|first1=Robert|title=Prodromus florae Novae Hollandiae|date=1810|location=London|pages=324–325|url=https://id.biodiversity.org.au/instance/apni/514489|accessdate=1 March 2017}} 5 : Caladenia|Plants described in 1810|Endemic orchids of Australia|Orchids of Victoria (Australia)|Orchids of Tasmania |
