A new species and a new synonym in Peruvian Senecio (Compositae)

Abstract

The species Senecio contumazensis sp. nov. from the southern department of Cajamarca, in northwestern Peru, is described herein. It shows morphological affinities with species of the Senecio series Otopteri, especially with the Bolivian Senecio sepium. In addition, the putative endemic Senecio piurensis from northern Peru is synonymized with S. pericaulis, a species previously described from southern Ecuador. Discussions on the morphology of these species, illustrations, and a distribution map are provided.
