Anemia tabascana (Anemiaceae), a new species from southeastern Mexico

We describe Anemia tabascana (Anemiaceae), a new species from the state of Tabasco in southeastern Mexico. This species is similar to Anemia phyllitidis and Anemia×paraphyllitidis; however, A. tabascana has free veins in the pinnae, and the rachis and distal part of the stipe are glabrescent (vs. at least sparsely pubescent in presumably related species). The closest relative of the new species may be Anemia nicaraguensis, which has a similar venation pattern and inclined fertile pinnae but differs in having more rounded or subacute pinna tips, fewer and more equilateral pinnae, and more numerous hairs on the stipes and blades.
