My field work is centered in Colombia, and Papua New Guinea. I am based at the Royal Botanic Garden Edinburgh (E). If you have any ferns that you want identified, please send them to me!

Amazing fern! This species is different from other Jamesonia according to my memory, And the indument and sori look very like an Asian fern Pleurosoriopsis makinoi.
Yes, nearly with the same Sori! but the Pleurosoriopsis makinoi belong to Polypodiaceae now, and distributed in east Asia. Anyway, it’s wonderful of this two ferns! haha….
Yes, this is quite different from Jamesonia in the old sense, which are extremely reduced alpine taxa. This species was previously treated in Eriosorus, but phylogenetic analyses (Sanchez-Baracaldo, 2004) demonstrated that the former genus was polyphyletic and nested in the latter. It represents a rather remarkable case of convergent evolution toward an alpine morphotype. Because Jamesonia is the older name, the species of Eriosorus were transferred to Jamesonia by Christenhusz et al. (2011).
