The bold-italic parts are diagnostic descriptions, generated with the aid of Intkey (Dallwitz et al. 1993). They distinguish each taxon in at least two respects from every other taxon. Authors have chosen additional characters to appear in bold-italic, on the basis of their diagnostic value. • Pteridophytes
