Caladenia abbreviata, commonly known as the coastal spider orchid,[1] is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It has a single erect, hairy leaf and up to three pale, creamy-yellow flowers on a flowering stem up to Шаблон:Convert high. Although the flowers have long, thread-like petals and sepals, they are shorter and darker than those of other spider orchids. It is a rare, relatively recently discovered species although often found near human activities.
Description
Caladenia abbreviata is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf Шаблон:Convert long and Шаблон:Convert wide. The inflorescence is a raceme, Шаблон:Convert high with up to three flowers, each flower Шаблон:Convert long and Шаблон:Convert wide. The dorsal sepal is erect and the lateral sepals and petal spread widely, have dark, glandular tips and are less than Шаблон:Convert long. The labellum is white with prominent red stripes with two rows of white calli along its centre. Flowering occurs between October and early December and is followed by a non-fleshy, dehiscent capsule containing a large number of seeds.[1][2][3]
Taxonomy and naming
Caladenia abbreviata was first formally described by Stephen Hopper and Andrew Brown in 2001 from a specimen collected at Cosy Corner near Torbay. The description was published in Nuytsia.[4] The specific epithet (abbreviata) is a Latin word meaning "shortened",[5] referring to the relatively short petals and lateral sepals of this species.[1]
Distribution and habitat
Coastal spider orchid occurs in scattered locations between Yallingup and William Bay in the Warren biogeographic region[6] where it grows in consolidated sand dunes and in disturbed places such as the edges of tracks and firebreaks.[1][2][7]
Ecology
Caladenia abbreviata attracts its pollinator via sexual deception. It is pollinated by an undescribed species of thynnine wasp from the genus Rhytidothynnus.[8]
Conservation
Caladenia abbreviata is classified as "Priority Three" by the Western Australian Government Department of Parks and Wildlife,[6] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[9]
