Caladenia incrassata, commonly known as the puppet clown orchid is a species of orchid endemic to the south-west of Western Australia. It has a single, hairy leaf and usually only one greenish-yellow and red flower which has a red-striped labellum. Description Caladenia incrassata is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, long and about wide. Usually a single greenish-yellow and red flower long and wide is borne on a stalk tall. All three sepals have thickened, club-like pinkish to yellowish glandular tips. The dorsal sepal is erect or sometimes curved forwards, long and about wide. The lateral sepals are long and wide and the petals are long and about wide. The labellum is long and wide and yellowish-green to pinkish with a red tip, the end of which is turned downwards. The labellum has smooth edges and there is a dense band of purplish-red calli up to long in the centre. Flowering occurs from August to September. Taxonomy and naming Caladenia incrassata was first described in 2001 by Stephen Hopper and Andrew Phillip Brown from a specimen collected on Muddarning Hill north of Koolyanobbing and the description was published in Nuytsia. The specific epithet (incrassata) is a Latin word meaning "thickened" referring to the thicked sepals of this species. (The dorsal sepal of the similar Caladenia brevisura is not thickened and the lateral sepals are less so.) Distribution and habitat The puppet clown orchid occurs between Paynes Find and Southern Cross in the Avon Wheatbelt, Coolgardie, Murchison and Yalgoo biogeographic regions where it grows under shrubs on granite outcrops and on ironstone hills. Conservation Caladenia incrassata is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
