Abstract

Two species of Persicaria (L.) Mill. are reported for the first time in the Neotropics. Persicaria glabra (Willd.) M. Gómez is reported for the first time as part of the flora of the Yucatan Peninsula, Mexico, and Persicaria barbata (L.) H. Hara is newly recorded from Mexico and the Americas. We present morphological descriptions of these two species along with figures, a distribution map, and a dichotomous key for the identification of the six species of Persicaria from the Yucatan Peninsula.
