Note: Senecio hohenackeri Sch.Bip. ex Wedd., Chloris Andina 1: 131 (1856) was given in Foster (1958: 217) but it is clear that in citing Schultz Bipontinus original description Weddell was not publishing a new name. Cabrera (1985: 198) clearly considered Cuatrecasas taxon the same even though Cuatrecasas had noted differences in the shape of the involucre and calycle, but not what they were. Several collections of Schultz Bipontinus taxon were cited by Cabrera from Bolivia.
