Four New Species of Adiantum (Pteridaceae) from the Guianas

Abstract We describe, discuss, and illustrate four new species of the fern genus Adiantum (Pteridaceae): one from Guyana (A. cremersii Boudrie & J. Prado) and two from French Guiana (A. granvilleanum Boudrie & J. Prado and A. latipinnulum Boudrie & J. Prado), and A. rivularis Boudrie & J. Prado that occurs in Guyana and French Guiana. The typification and application of the name A. oyapokense Jenman are also discussed.
