Plant collections conducted in connection with ethnobotanical studies carried out with the Guaraní peoples of Misiones Province, Argentina, resulted in the discovery of a new species of Hypericum L. (Hypericaceae), which is characterized by its epigeous herbaceous scions produced seasonally from subterranean stems or roots. This species, H. robsonii H. A. Keller & S. Crockett, is described and illustrated for the first time. Information about its ecology, habitat and distribution, phenology and ethnobotany is provided.
