Taxonomy and naming

Caladenia splendens was first formally described in 2001 by Stephen Hopper and Andrew Phillip Brown from a specimen collected near Gingin and the description was published in Nuytsia.[4] The specific epithet (splendens) is a Latin word meaning "splendid" or "resplendent"[5] referring to the "brilliant white" colour of this orchid.[2]

Distribution and habitat

The splendid spider orchid is found between Gingin and Frankland in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain biogeographic regions where it grows in woodland and forest in moist gullies and other places where water is available in winter.[1][2][3][6]

Caladenia splendens is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.[6]
