[2][3][4] Caladenia pectinata was first formally described by Richard Rogers in 1920 and the description was published in Transactions and Proceedings of the Royal Society of South Australia.

[1][5] The specific epithet (pectinata) is a Latin word meaning "comb-like"[6] referring to the fringe on the sides of the labellum.

[2][3][4][7] Caladenia pectinata is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
