The invaluable labor of Antonio Raimondi (1824-1890) to study and record the natural history of Peru is well known, however, his contribution to the plant taxonomy has not been so well documented. Raimondi described five new species, which mostly were wrongly ascribed to other botanists or just overlooked. A recent contribution has been addressed to bring into light this issue, however, the adopted taxonomic decisions regarding the Compositae names require some amendments. Herein, we discuss the taxonomic identity of the names Cryptochaete andicola Raimondi and Culcitium discolor Raimondi. Both names are neotypified in order to remove any uncertainty surrounding their application. Culcitium discolor is proposed as a new synonym for Senecio rhizomatus Rusby.
