Regina Y. Hirai, Rafael Cruz, Jefferson Prado

• Hemionitis umbrosa (Pteridaceae) is described from the state of Goiás in central Brazil. It resembles H. tomentosa and was previously identified as such; however, it can be distinguished by having rhizome scales serrulate and spores cristate-reticulate. In contrast, H. tomentosa has rhizome scales entire or rarely sparsely denticulate and spores cristate. The new species is morphologically and anatomically described, illustrated, and a key is provided to the species of Hemionitis with free veins.
