"Phlebodium aureum" is a member of a very small, and recently discovered genus. It was split from the genus "Polypodium", and the split is still apparent in the multitude of synonyms available for "Phlebodium aureum". "Phlebodium" is one of the 178 genera in the family Polypodiaceae. Additionally, the family Polypodiaceae is broken into a number of subfamilies, with "Phlebodium" a member of the non-grammatid tribe within the subfamily Polypodioideae. Members of the non-grammatids in this subfamily include the genera "Phlebodium" as well as "Polypodium", from which "Phlebodium" is derived and which most likely is its closest relative. Other members include "Pecluma", "Pleopeltis", "Microgramma", and "Pleurosoriopsis". A bootstrapping technique proves that, at a 90% confidence level, the polypodiaceous ferns form a sister relationship with tree ferns. However, further phylogenetic studies need to be conducted regarding the current status of the genus, and which of the species are the most related.
