Caladenia mesocera, commonly known as the narrow-lipped dragon orchid, is a species of orchid endemic to the south-west of Western Australia. It has a single erect, hairy leaf and usually only one greenish-yellow and red flower with a relatively long, insect-like labellum. Its distribution is further inland than that of most other caladenias.
Description
Caladenia mesocera is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, Шаблон:Convert long and Шаблон:Convert wide. Usually only one greenish-yellow and red flower Шаблон:Convert long and Шаблон:Convert wide is borne on a stalk Шаблон:Convert tall. The dorsal sepal is bent backwards, Шаблон:Convert long and Шаблон:Convert wide. The lateral sepals are Шаблон:Convert long, Шаблон:Convert wide and spread widely. The petals are Шаблон:Convert long and about Шаблон:Convert wide and downswept. The labellum is Шаблон:Convert long and Шаблон:Convert wide, insect-like and stiffly hinged. It is densely hairy, greenish-yellow and red with a "false head" Шаблон:Convert across at its highest point and there is a horn-like gland Шаблон:Convert long either side of the "head". Flowering occurs from August to early October.[1][2][3]
Taxonomy and naming
Caladenia mesocera was first described in 2001 by Stephen Hopper and Andrew Phillip Brown and the description was published in Nuytsia.[4][5] The specific epithet (mesocera) is said to be derived from the Greek words meso meaning "middle" and ceras meaning "horn", referring to the position of the horn-like glands between the labellum claw and claw connection, a feature that readily distinguishes Caladenia mesocera from C. barbarossa.[5][6] The proper word for "middle" in ancient Greek is mesos (μέσος).[7]
Distribution and habitat
The narrow-lipped dragon orchid occurs between Bonnie Rock and Lake Moore east of Wubin, in the Avon Wheatbelt, Coolgardie, Geraldton Sandplains, Mallee and Yalgoo biogeographic regions where it grows near salt lakes and in other places that are moist in winter.[1][2][3][8]
Conservation
Caladenia mesocera is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[8]
