Tribe Helenieae Benth. & Hook. s. s. (Asteraceae) in southern Brazil

Abstract

We performed a taxonomic study of tribe Helenieae (Asteraceae) in southern Brazil. The study was conducted by means of literature review, consultation to herbarium specimens, and field collections covering the three states from southern Brazil: Paraná, Rio Grande do Sul, and Santa Catarina. We present here: descriptions; identification keys; data on habitat, geographic distribution, and flowering and fruiting periods; general remarks on species conservation status; nomenclatural and taxonomic discussions; photographs; and illustrations of representatives from the tribe. A lectotype of Hymenopappus anthemoides Juss. is designated. A total five taxa belonging to three genera were surveyed, four of those taxa being of natural occurrence (two of them having only one historical record, each) and one being of sub-spontaneous occurrence.
