Abstract

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.
