About the Author
Michael Sundue
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!
Wow! Is this a grammitid?
Yes, and weirdly enough, this clade is nested within Oreogrammitis and Radiogrammitis which look much more “typical”. See:
Sundue, Michael A., et al. “Global phylogeny and biogeography of grammitid ferns (Polypodiaceae).” Molecular phylogenetics and evolution 81 (2014): 195-206.
Cool! That’s a beautiful paper. I see that Oreogrammitis and Radiogrammitis are a mess…
