Taxonomy and naming
Caladenia longicauda was first formally described by John Lindley in 1840 and the description was published in A Sketch of the Vegetation of the Swan River Colony.[5] In 2001 Stephen Hopper and Andrew Brown described eleven subspecies, including subspecies redacta and the descriptions were published in Nuytsia.[6] The subspecies name (redacta) is a Latin word meaning "edited" or "reduced"[7] referring to the relatively small size of the flower compared with those of the other subspecies.[2]
Distribution and habitat
The tangled white spider orchid mainly occurs between Collie, Mount Barker and York in the Avon Wheatbelt and Jarrah Forest biogeographic regions where it grows in flat areas which are inundated in winter.[1][2][3][8]
Conservation
Caladenia longicauda subsp. redacta is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[8]
