Caladenia ancylosa, commonly known as the Genoa spider orchid,[1] is a plant in the orchid family Orchidaceae and is endemic to Victoria. It is a ground orchid with a single hairy leaf and a single cream-coloured flower with red markings.

Description

Caladenia ancylosa is a terrestrial, perennial, deciduous, herb with an underground tuber and a single hairy leaf, Шаблон:Convert long and Шаблон:Convert wide.[2][3]

A single flower is borne on a spike Шаблон:Convert high. The dorsal sepal is erect, oblong to lance-shaped, Шаблон:Convert long and about Шаблон:Convert wide. It tapers near the end which terminates in a glandular structure Шаблон:Convert long. The lateral sepals are oblong to lance-shaped, Шаблон:Convert long, Шаблон:Convert wide and end in a gland similar to the one on the dorsal sepal. The petals are Шаблон:Convert long, about Шаблон:Convert wide and taper to a point. The labellum is a broad egg-shape, curves forward, Шаблон:Convert long and Шаблон:Convert wide when flattened. The labellum is cream-coloured at its base but red nearer the tip. There are 7 to 10 pairs of calli along the edge of the labellum, decreasing in length towards its front. There are six rows of foot-shaped calli in the centre of the labellum, also smaller towards the tip. Flowering occurs in September and October.[3]

Taxonomy and naming

The species was first formally described by David L. Jones in 2006 and given the name Arachnorchis ancylosa.[4] The description was published in Australian Orchid Research. In 2007, Gary N. Backhouse transferred the species to Caladenia as C. ancylosa and the change was published in The Victorian Naturalist.[5] Jones derived the specific epithet (ancylosa) "from the Greek ancylosis, stiffening of the joints; in reference to the stiffly spreading lateral sepals and petals".[2]

Distribution and habitat

Caladenia ancylosa is only known from far east Gippsland where it grows in the shrub layer of tall open forest near Genoa.[3]

Conservation

This species is classified as "Vulnerable" by the Victorian government.[3][1]
