A new species of Blechnum L. (Blechnaceae, Polypodiopsida) from central-western Brazil, with an updated key to the species in the country

We describe a new species of Blechnum from Mato Grosso, Brazil: Blechnum rivulorum sp. nov. This new species was discovered as a result of visits to the herbaria BM, K, P, PR, and S, as part of the Reflora Project, by the first author. We also indicate its position in a new Blechnum phylogeny. Additionally, we confirm the occurrence of Blechnum meridense Klotzsch in Brazil and provide an updated key to all species of Blechnum in the country.
