}} Caladenia magnifica, commonly known as the magnificent spider orchid is a species of orchid endemic to Victoria. It has a single leaf and one or two reddish crimson or yellow flowers streaked with crimson and with dark reddish tips. It has not been sighted since 1979 and is presumed to be extinct. DescriptionCaladenia magnifica is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect leaf, {{convert|100-150|mm|in|sigfig=1|abbr=on}} long and {{convert|15-20|mm|in|sigfig=1|abbr=on}} wide. One or two reddish crimson, or yellow flowers streaked with crimson, {{convert|70-100|mm|in|sigfig=1|abbr=on}} wide are borne on a stalk {{convert|200-300|mm|in|sigfig=1|abbr=on}} tall. The sepals and petals have long, dark reddish, thread-like tips. The dorsal sepal is erect, {{convert|70-100|mm|in|sigfig=1|abbr=on}} long and {{convert|3-4|mm|in|sigfig=1|abbr=on}} wide. The lateral sepals are {{convert|70-100|mm|in|sigfig=1|abbr=on}} long, {{convert|4-6|mm|in|sigfig=2|abbr=on}} wide and spreading with drooping ends. The petals are {{convert|60-80|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|18-22|mm|in|sigfig=1|abbr=on}} long, {{convert|16-18|mm|in|sigfig=1|abbr=on}} wide and dark reddish-purple. The tip of the labellum is curled under and the sides are turned up and have many purplish teeth up to {{convert|4|mm|in|sigfig=1|abbr=on}} long. There are four or six rows of reddish-purple calli up to {{convert|2|mm|in|sigfig=1|abbr=on}} long in the centre of the labellum. Flowering occurs from September to October.[1][2][3]Taxonomy and namingThe magnificent spider orchid was first described in 1936 by William Nicholls and given the name Caladenia patersonii var. magnifica and the description was published in The Victorian Naturalist.[4][3] In 1989 David Jones and Geoffrey Carr raised it to species status.[5][6] The specific epithet (magnifica) is a Latin word meaning "noble", "eminent" or "splendid".[7] Distribution and habitatThe magnificent spider orchid occurs in the Clydesdale district near Guildford in central Victoria where it grows in open forest with a sparse understorey. It has not been seen since 1979 and is presumed to be extinct.[1][2] ConservationCaladenia magnifica is classified as "extinct" under the Victorian Government Flora and Fauna Guarantee Act 1988.[2]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=57}} {{Taxonbar|from=Q15287576}}2. ^1 2 {{cite web|last1=Jeanes|first1=Jeff|title=Caladenia magnifica|url=https://vicflora.rbg.vic.gov.au/flora/taxon/e8f15233-3f6d-4042-bdcb-b4a6d98c006f|publisher=Royal Botanic Gardens, Victoria: vicflora|accessdate=20 February 2017}} 3. ^1 {{cite journal|last1=Nicholls|first1=William Henry|title=Orchid Notes: Two new varieties|journal=The Victorian Naturalist|date=1936|volume=52|page=167|url=https://www.biodiversitylibrary.org/item/125789#page/207/mode/1up|accessdate=20 February 2017}} 4. ^{{cite web|title=Caladenia patersonii var. magnifica|url=https://id.biodiversity.org.au/instance/apni/514611|publisher=APNI|accessdate=20 February 2017}} 5. ^1 2 {{cite web|title=Caladenia magnifica|url=https://id.biodiversity.org.au/instance/apni/514256|publisher=APNI|accessdate=20 February 2017}} 6. ^{{cite journal|last1=Clements|first1=Mark Alwyn|title=Catalogue of Australian Orchidaceae|journal=Australian Orchid Research|date=1989|volume=1|page=27}} 7. ^{{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.|page =504}} 4 : Caladenia|Orchids of Victoria (Australia)|Endemic orchids of Australia|Plants described in 1936 |
