Abstract

A treatment of the lycophytes of the Northern Pará Biodiversity Corridor within the Guiana Endemism Center is presented. This article is part of the project “Diagnóstico da Biodiversidade das Unidades de Conservação estaduais do Mosaico Calha Norte, Estado do Pará”. The treatment includes keys as well as species descriptions. In the study area 14 species distributed in four genera (Palhinhaea, Phlegmariurus, Pseudolycopodiella and Selaginella) were registered. The most diverse genus was Selaginella with 10 species, of which S. fragilis A. Braun and S. revoluta Baker are new records for Pará, and S. gynostachya Valdespino and S. sandwithii Alston are reported here as new to the Brazilian flora.
