Description
Caladenia congesta is a terrestrial, perennial, deciduous, herb with an underground tuber and a single, sparsely hairy, linear leaf, Шаблон:Convert long and Шаблон:Convert wide. Up to three bright pink flowers are borne on a spike Шаблон:Convert high. The sepals and petals are lance-shaped, spreading, Шаблон:Convert with dark red glandular hairs on their backs, the petals narrower than the sepals. The dorsal sepal curves and forms a hood over the column. The labellum is Шаблон:Convert long and Шаблон:Convert wide when flattened and has three lobes. The mid-lobe is oblong to lance-shaped and completely covered by two closely spaced rows of shiny, dark crimson to black calli. The lateral lobes of the labellum are sickle-shaped, pink and erect or slightly spreading. Flowering occurs from October to January.[1][2]
Taxonomy and naming
Caladenia congesta was first formally described by Robert Brown in 1810 and the description was published in Prodromus Florae Novae Hollandiae.[3][4] The specific epithet (congesta) is a Latin word meaning "dense", "heaped up" or "thick".[5]
Distribution and habitat
Black-tongue caladenia grows in a wide range of habitats from forest to heath in sandy or clay loam south from Wellington New South Wales. It is widespread although not common, in Victoria, in northern Tasmania and in the far south-east corner of South Australia.[1][2][6][7]
Conservation
Caladenia congesta is listed as "Endangered" under the Tasmanian Threatened Species Protection Act 1995.[6]
