Tags: Fern.

Eriosorus and Jamesonia are two closely related genera in the taenitoid group of the core pteridoid ferns. They have long been recognized as being closely related and recent genetic evidence has demonstrated that they are both paraphyletic genera but only in regards to each other. Thus they must be combined as a single larger genus or have the generic boundaries redefined.
