Abstract

The fern genus Phlebodium is traditionally described as having a row of costal areoles lacking included veins, with the sori located in extra-costal areoles and each sorus served by two veinlets. The discovery of a hybrid between Phlebodium pseudoaureum and Polypodium pleurosorum raises questions about the limits of Phlebodium and necessitates a revised taxonomic circumscription of the genus.
