Jamesonia
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. The two genera are being temporarily considered here under Jamesonia, because 1) this is the older genus name, and 2) the core genus forms a clearly defined monophyletic group considered by itself, while there is no such clear clade for Eriosorus.
