ABSTRACT
Pfaffia cipoana and Pfaffia rupestris (Amaranthaceae) are two new species of the Brazilian flora. These species are included in the section Pfaffia, which has the largest number of species in the Brazilian territory. Pfaffia cipoana is close to P. denudata but it is set apart mainly by the greater length and width of the leaves and oblong sepals. Pfaffia rupestris differs as it is extremely leafy, with small, opposite and verticillate leaves. The two species were recognized during the revision of the genus Pfaffia in Brazil. Descriptions, illustrations, observations about the habitat and the geographical distribution of the new species are presented.
