Taxonomic Notes on Some East Asian Pteridophytes

Following results of recent studies, Huperzia myriophyllifolia (Huperziaceae), Lycopodium subinundatum (Lycopodiaceae), and Polystichum pseudodeltodon, P. pseudostenophyllum, P. subapiciflorum, and P. subobliquum (Dryopteridaceae) are recognized/reinstated. A new combination, Pseudolycopodiella subinundata, is made based on L. subinundatum. Spinulum lioui (Lycopodiaceae) is reported as a new record for most part of China and other Asian countries.
