Caladenia leptoclavia, commonly known as the thin-clubbed spider orchid, is a plant in the orchid family Orchidaceae and is endemic to New South Wales. It is a ground orchid with a single hairy leaf and a single pale cream-coloured to yellow flower with dark reddish stripes.

Description

Caladenia leptoclavia is a terrestrial, perennial, deciduous, herb with an underground tuber and a single, lance-shaped, dull green hairy leaf, Шаблон:Convert long and Шаблон:Convert wide with a reddish base. Usually only a single cream-coloured to yellow flower with dark reddish, central stripes is borne on a thin, wiry, hairy spike Шаблон:Convert tall. The sepals have thin, dark red to blackish club-like ends Шаблон:Convert long. The dorsal sepal is erect, Шаблон:Convert long and about Шаблон:Convert wide near the base. The lateral sepals are a similar size and shape to the dorsal sepal but spread widely and stiffly. The petals are Шаблон:Convert long and about Шаблон:Convert wide and droop slightly. The labellum is egg-shaped to heart-shaped, about Шаблон:Convert long and Шаблон:Convert wide and is sometimes all red, or dark maroon with a white base. The tip of the labellum curls under and there are between eight and ten red teeth up to Шаблон:Convert long on each side of the labellum. There are four rows of calli Шаблон:Convert long along the mid-line of the labellum and which decrease in size towards the tip. Flowering occurs from September to October.

Taxonomy and naming

Caladenia leptoclavia was first formally described by David Jones in 1991 from a specimen collected near Bethungra, and the description was published in Australian Orchid Research. The specific epithet (leptoclavia) is derived from the Ancient Greek word λεπτός leptos meaning "thin" or "slender",Шаблон:Rp and the Latin word clava meaning "club",Шаблон:Rp referring to the thin "clubs" on the sepals.

Distribution and habitat

Thin-clubbed spider orchid has a restricted distribution in New South Wales where it is only known from near Bethungra, Cowra and Eugowra where it grows in forest.
