A new combination is required in Conocliniopsis (Compositae: Eupatorieae: Gyptidinae).

A new combination, , in R.M.King & H.Rob. (Compositae: Eupatorieae: Gyptidinae) is provided.

R.M.King & H.Rob. Colla’s name pre-dates that of de Candolle’s , the basionym of ; a new combination is necessary. A full synonymy of is provided, types indicated, and other issues discussed.
