This first revision of the genus Deyeuxia in Argentina revealed 58 native taxa from America, three of them endemic to Argentina, and the remaining ones also growing in Bolivia, Brasil and Chile. Three new taxa are described for science: Deyeuxia alba subsp. breviaristata (Argentina, Brasil and Uruguay); Deyeuxia heterophylla var. puberilemma (Perú); Deyeuxia trichodonta var. hirsuta from (Argentina: Salta).
