Abstract

Species of Sisyrinchium from Southern Brazil represent 31% and 86% of the genus diversity throughout the Americas and the Brazilian territory, respectively. However, new species are still being discovered and three are presented here:
S. pampeanum, from the Pampa Biome and S. diversicarpum and S. sectiandrum, from the Atlantic Forest Biome. The taxa are described, illustrated and taxonomic comments, conservation status and comparisons with related species are provided.
