Caladenia barbarossa, commonly known as the common dragon orchid is a species of orchid endemic to the south-west of Western Australia. It can be distinguished by its distinctive labellum which is attractive to species of male thynnid wasps.
Description
Caladenia barbarossa is a terrestrial, perennial, deciduous, herb with an underground tuber and a single hairy leaf, Шаблон:Convert long and Шаблон:Convert wide. In spring it produces one, rarely two flowers on the end of a stalk Шаблон:Convert tall, each flower Шаблон:Convert long and Шаблон:Convert wide. The flowers are cream coloured to greenish-yellow with red markings. The dorsal sepal is erect, Шаблон:Convert long, about Шаблон:Convert wide. The lateral sepals spread apart below the flower and are Шаблон:Convert long, Шаблон:Convert wide. The petals also spread widely, are slightly shorter and narrower than the sepals and have their tips rolled inwards. The labellum resembles the body of a wingless female thynnid wasp and is stiffly hinged to the column. The labellum has a dummy insect abdomen, Шаблон:Convert long, Шаблон:Convert wide and curved with many maroon-coloured hairs and calli. The false head is blackish, about Шаблон:Convert wide with two large, thick calli about Шаблон:Convert long on either side of the "head".[1][2]
Taxonomy and naming
Caladenia barbarossa was first described by Reichenbach in 1871 in Beitrage zur Systematischen Pflanzenkunde, from a specimen collected by James Drummond in 1843, near the Swan River.[3][4][5] In a review of the genus Caladenia in 2004, David Jones and Mark Clements proposed a name change to Drakonorchis barbarossa[6] but the change has not been widely adopted. The specific epithet was originally Barbarossa, indicating that the plant was named after Barbarossa, named thus for his red beard also.[4]
Distribution and habitat
The common dragon orchid is widespread and common, between Bindoon, Ravensthorpe and Esperance in the Avon Wheatbelt, Esperance Plains, Jarrah Forest and Mallee biogeographic regions. It grows in sandy or clayey loams in moist situations in a wide range of habitats but especially in Casuarina thickets.[1][2][7]
Ecology
Common dragon orchid is pollinated by male thynnid wasps when they try to copulate with the flower.[2] A male Thynnoides bidens has been photographed on the labellum of a flower of this species.[8]
Conservation
Caladenia barbarossa is classified as "Not Threatened" by the Western Australian Government Department of Parks and Wildlife.[7]
