The genus "Phlebodium" is exemplified by containing rows of areoles that lack included veins, and each sorus served by two different veins. Correll and Correll, two authors responsible for thirty years of classification since Flora was introduced in 1982, documented "Phlebodium aureum" as "Polypodium aureum" as recently as 1982. However, this creation of the new genera is warranted based on some notable differences. For instance, Giudice et al. points out that the sori on "Phlebodium" are more smooth and rounded when compared to other groups within the family Polypodiaceae. Additionally, studies on spores and size of the mature plant prove that "Phlebodium" contrasts severely from the rest of its family, providing the creation of the genera. The division of genera within the Polypodiaceae is fairly gray, considering that systematically, gametophytes differ only very slightly amongst different genera.
