Abstract

On-going studies of the tribe Senecioneae (Compositae) led us to record for the first time five species for Peru, i.e., Dendrophorbium scytophyllum, Pentacalia luteynorum, P. millei, P. riotintis, and Senecio puchei. In addition, the name P. lanceolifolia is synonymized with P. andrei, as well as P. hitchcockii and P. huamaliensis with P. theifolia, and P. tillettii with P. riotintis. Each species is discussed and compared against similar taxa. The name S. puchei is neotypified.
