A tribo Tageteae (Asteraceae) no sul do Brasil

Abstract

Tribe Tageteae in southern Brazil. The tribe Tageteae is predominantly composed by herbs and subshrubs, most with pellucid oil glands in the leaves and involucral bracts. Our aim was to study specimens of the tribe in the three state of southern Brazil. For this study, we collected specimens and we reviewed herbarium exsicata from 19 herbaria of southern and southeastern Brazil, in addition to images of exsicata from foreign herbaria. We provide descriptions of genera and species from southern Brazil, identification keys, data on habitat, geographical distribution, flowering and fruiting period, as well as photographs, illustrations and taxonomic and additional nomenclatural comments. Twelve species from three genera were considered, ten are native and two cultivated. The largest genus is Porophyllum Guett., with seven species.
