Abstract

We present the taxonomic treatment of the Xyridaceae family for the state of Paraná. It is represented
exclusively by the genus Xyris, with 22 species typical of grasslands. Three new records are reported for the
state: Xyris glandacea, X. metallica and X. uninervis, all of them extends its distribution area to southern
Brazil. Other novelties are a new synonym (Xyris simulans var. subtortula under Xyris asperula) and the
reestablishment of Xyris dusenii. An identification key, descriptions, comments, illustrations and data on the
geographical distribution of the species are provided.
