title: The species of Puccinia on Piptocarpha and Vanillosmopsis in the Neotropics.
abstract: Nine species of Puccinia are known on Piptocarpha and one on closely related Vanillosmopsis. All are mostly from Brazil. Six of the nine Puccinia species on Piptocarpha are proposed as new: Puccinia bipolaris, P. calida, P. douradae, P. macumba, P. manuelensis and P. pipta. Three species are reduced to synonyms of P. piptocarphae: P. leptoderma, P. jahnii, and P. pycnothelis. P. vanillosmopsidis is reduced to a synonym of P. velata on Vanillosmopsis. A key to aid in the identification of the 10 species of Puccinia on Vernonieae is provided. Nomenclature, descriptions, illustrations and notes are presented for each species.
