Chiloglottis reflexa explained

Chiloglottis reflexa, commonly known as the short-clubbed wasp orchid, is a species of orchid endemic to the south-eastern Australia. It has two broad leaves and a single greenish-bronze or purplish flower with an ant-like callus covering most of the top of the labellum.

Description

Chiloglottis reflexa is a terrestrial, perennial, deciduous, herb with two egg-shaped to elliptic leaves NaNsigfig=1NaNsigfig=1 long and NaNsigfig=1NaNsigfig=1 wide. A single greenish-bronze or purplish flower NaNsigfig=1NaNsigfig=1 long and NaNsigfig=1NaNsigfig=1 wide is borne on a flowering stem NaNsigfig=1NaNsigfig=1 high. The dorsal sepal is spatula-shaped, NaNsigfig=1NaNsigfig=1 long and NaNsigfig=1NaNsigfig=1 wide. The lateral sepals are linear, NaNsigfig=1NaNsigfig=1 long, less than 1sigfig=1NaNsigfig=1 wide and curve downwards. There is a glandular tip NaNsigfig=1NaNsigfig=1 long on the end of the dorsal sepal and NaNsigfig=1NaNsigfig=1 long on the lateral sepals. The petals are oblong, NaNsigfig=1NaNsigfig=1 long, about 2.5sigfig=1NaNsigfig=1 wide and turned downwards near the ovary. The labellum is held horizontally, diamond-shaped, NaNsigfig=2NaNsigfig=2 long and NaNsigfig=1NaNsigfig=1 wide. The callus resembles a large black ant surrounded by thin, stalked glands and covers most of the labellum. The column has narrow wings. Flowering occurs from December to May.[1] [2] [3]

Taxonomy and naming

This orchid species was first formally described in 1806 by Jacques Labillardière who gave it the name Epipactis reflexa and published the description in Novae Hollandiae Plantarum Specimen.[4] In 1917 George Claridge Druce changed the name to Chiloglottis reflexa.[5] The specific epithet (reflexa) is a Latin word meaning "bent" or "turned back".[6]

Distribution and habitat

The short-clubbed wasp orchid grows in a wide range of habitats but is most common in coastal and near-coastal forest and heath. It occurs in New South Wales south from the Blue Mountains, in southern Victoria and in Tasmania.
