[Peru: Tatanara, Aug. m. 1854]. Holotype: P; isotypes G, GOET, K, S. Cabrera (1985: 135) suggested that the holotype was in B, although for all other Schultz Bipontinus types they are cited as in P.

Note: Senecio curvidens Sch.Bip. ex Klatt, Leopoldina 24: 127 (1888) is often applied to this name as the valid place of publication, based apparently on Senecio curvidens Sch.Bip. which was considered a nom. nud. Schultz Bipontinus clearly provided a short diagnosis. The citation, however is wrong and should be Leopoldina 23 [1886](1887), as the likely preprint in Kew also suggests that it was published on p. 9.
