Caladenia cracens, commonly known as the elegant caladenia, is a plant in the orchid family Orchidaceae and is endemic to Tasmania. It is a ground orchid with a single, sparsely hairy leaf and a single pale to dark pink or mauve flower on a thin, wiry stem Шаблон:Convert high.

Description

Caladenia cracens is a terrestrial, perennial, deciduous, herb with an underground tuber and which grows singly or in loose groups. It has a single, sparsely hairy, narrow linear leaf, Шаблон:Convert long and Шаблон:Convert wide.[1]

A single, sweetly-scented flower, Шаблон:Convert across, is borne on a thin, wiry spike Шаблон:Convert high. The dorsal sepal is egg-shaped with the narrow end towards the base, Шаблон:Convert long, Шаблон:Convert wide and forms a hood over the labellum and column. The lateral sepals and petals are lance-shaped, Шаблон:Convert long, Шаблон:Convert wide and pale to dark pink. The sepals and petals are glabrous on the front but densely covered with glandular hairs on the back and are held more or less horizontally and spreading from each other. The labellum has three lobes, is broadly egg-shaped when flattened and curves forward, Шаблон:Convert long and Шаблон:Convert wide and has five to eight pairs of linear teeth along the edge, decreasing in size towards the front. There are between two and four irregular rows of thin cream or yellow calli along the centre part. The lateral lobes of the labellum are erect and partly surround the column. The column is about Шаблон:Convert long, Шаблон:Convert wide and green to whitish with red markings and has narrow wings. Flowering occurs between late September and early November and is followed by the fruit which is a papery capsule.[1][2][3][4]

Taxonomy and naming

Caladenia cracens was first formally described by David L. Jones in 1996 and the description was published in Muelleria from a specimen collected in the Lenah Valley near Hobart.[5] The specific epithet (cracens) is a Latin word meaning "neat" or "graceful",[6] adjectives "which apply to this graceful species".[1]

Distribution and habitat

Elegant caladenia is widespread in southern Tasmania where it grows in woodland and forest, less commonly in heath.[1][4]
