Up to three cream-coloured to dark pinkish-maroon flowers Шаблон:Cvt long and Шаблон:Cvt wide are borne on a stalk Шаблон:Cvt tall. The sepals and petals have long, thin, drooping, thread-like ends. The dorsal sepal is erect near its base, Шаблон:Cvt long and about Шаблон:Cvt wide. The lateral sepals are Шаблон:Cvt long and Шаблон:Cvt wide, the ends drooping vertically, the petals Шаблон:Cvt long, Шаблон:Cvt wide and similarly drooping. The labellum is Шаблон:Cvt long, Шаблон:Cvt wide, and cream-coloured with dark maroon lines, blotches and spots. The sides of the labellum have serrated edges or teeth and there are two rows of white, sometimes red-tipped calli along its mid-line. Flowering occurs from August to mid October.[1][2][3][4]
Taxonomy and naming
Caladenia pendens was first described in 2001 by Stephen Hopper and Andrew Phillip Brown in Nuytsia from specimens collected near Hyden in 1985.[5] The specific epithet (pendens) means "hanging down", referring to the lateral sepals and petals.[2]
In the same journal, Hopper and Brown described two subspecies of C. pendens and the names are accepted by the Australian Plant Census:
- Caladenia pendens Hopper & A.P.Br. subsp. pendens[6] - pendant spider orchid, has cream-coloured flowers with petals Шаблон:Cvt long and a labellum Шаблон:Cvt long from August to early October.[1][2][7]
- Caladenia pendens subsp. talbotii Hopper & A.P.Br.[8] - Talbot's spider orchid, has dark, pinkish-maroon flowers with petals Шаблон:Cvt long and a labellum Шаблон:Cvt long from September to mid October.[1][9]
Distribution and habitat
This spider orchid grows in a variety of habitats, including on granite outcrops, near salt lakes and swamps is found from Watheroo and Wongan Hills south to Wagin and Hyden in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest, Mallee, Swan Coastal Plain and Warren bioregions of south-western Western Australia.[1][7] Subspecies talbottii is restricted to winter-wet flats between York and Watheroo in the Jarrah Forest bioregion.[1][9]
Conservation
Caladenia pendens and its two subspecies are classified as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.[4][7][9]
