Caladenia ampla, commonly known as the dainty 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 flower which is sometimes yellowish-green flower with red stripes and sometimes entirely red.
Description
Caladenia ampla is a terrestrial, perennial, deciduous, herb with an underground tuber and a single hairy leaf, Шаблон:Convert long and Шаблон:Convert wide.[2]
A single flower (rarely two) is borne on a spike up to 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, 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 with red veins and a dark red tip, sometimes entirely red. There are 9 to 12 pairs of calli along the edge of the labellum, decreasing in length towards its front. There are four rows of foot-shaped calli in the centre of the labellum, also smaller towards the tip. Flowering occurs in September and October.[2]
Taxonomy and naming
The species was first formally described by David L. Jones in 2006 and given the name Arachnorchis ampla.[3][4] The description was published in Australian Orchid Research. In 2007, Gary Backhouse changed the name to Caladenia ampla and the change was published in "The Victorian Naturalist".[5] The specific epithet (ampla) is a Latin word meaning "large",[6] referring to the unusually broad labellum of this orchid.[4]
Distribution and habitat
Caladenia ampla is only known from the goldfields region of Victoria where it grows in mallee scrub and woodlands.[2]
Conservation
This species is classified as "Endangered" by the Victorian government.[1][2]
