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

Abstract

• A new combination, , in R.M.King & H.Rob. (Compositae: Eupatorieae: Gyptidinae) is provided. An earlier assessment of Prince Maximilian Wied-Neuwied’s collections (sent by Martius to Colla), proposed that Colla’s was a new synonym of (Kunth) R.M.King & H.Rob., a Colombian endemic. A critical assessment of Wied’s collection has indicated that the material, collected in Brazil near the Bahian coast, on the banks of the Rio Belmonte (= Rio Jequitinhonha), is conspecific with the plant more usually known as (DC.) 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.
