Caladenia abbreviata
Caladenia abbreviata, commonly known as the coastal spider orchid, 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 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 long and wide. The inflorescence is a raceme, high with up to three flowers, each flower long and wide. The dorsal sepal is erect and the lateral sepals and petal spread widely, have dark, glandular tips and are less than 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. Taxonomy and naming Caladenia abbreviata was first formally described by Stephen Hopper and Andrew Brown in 2001 from a specimen collected
