There has been confusion between Lepidomicrosorium subhemionitideum and Polypodium hymenodes Kunze due to an unacceptable lectotypification of Kunzes name with the collection A. Henry 9265B, the type collection of Polypodium subhemionitideum, which was not collected until much later than Kunzes publication. Polypodium hymenodes is here included within Microsorum membranaceum.
