Caladenia leptochila subsp. leptochila, commonly known as the narrow-lipped spider orchid,[1] is a plant in the orchid family Orchidaceae and is endemic to South Australia. It has a single leaf and one or two yellowish or red flowers. It differs from subspecies leptochila in the colour of its flowers, lack of toothed edges to its labellum, and its distribution.

Description

Caladenia leptochila subsp. leptochila is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect leaf, Шаблон:Convert long and Шаблон:Convert wide. One or two yellowish or red flowers Шаблон:Convert in diameter are borne on a stalk Шаблон:Convert tall. The sepals have thin, reddish, club-like glandular tips Шаблон:Convert long. The dorsal sepal is erect, Шаблон:Convert long and about Шаблон:Convert wide. The lateral sepals are about the same size as the dorsal sepal but are turned stiffly upwards. The petals are Шаблон:Convert long and about Шаблон:Convert wide and spread horizontally or turn upwards. The labellum is Шаблон:Convert long and Шаблон:Convert wide and red with the tip rolled under. The sides of the labellum lack the teeth of subspecies dentata but there are four rows of short, red calli along its mid-line. Flowering occurs from September to November.[1]

Taxonomy and naming

Caladenia leptochila was first formally described by Robert FitzGerald in 1882 and the description was published in The Gardener's Chronicle from a specimen collected on Mount Lofty.[2][3] In 2008 a new subspecies (Caladenia leptochila subsp. dentata) was described, with the result that Caladenia leptochila subsp. leptochila became an autonym.[4][5] The specific epithet (leptochila) means "narrow-lipped".[6]

Distribution and habitat

The narrow-lipped spider orchid occurs in the south-east of South Australia where it grows in clay or gravelly soils in shrubby forest in the Mount Lofty ranges.[1] It is thought to have been common in Victoria in the past but is now probably extinct in that state.[7]
