After the genus Phlegmariurus (Herter)Holub was proposed by J.Holub 1964, the repercussions are different, with some botanists accepting it, while others refusing. We take it as a separate genus since the related species from China are distinctly different from those of Huperzia Bernh. The plants of this genus in China are classified into three sections: Sect. Huperzioides H.S.Kung et L.B.Zhang, sect. nov.; Sect. Carinaturus (Herter)H. S. Kung et L. B.Zhang, comb. nov. and Sect. Phlegmariurus. A key to sections is given. The taxonomy on the new section, Sect. Huperzioides, is presented. Thirteen species are reported in China, involving 4 new combinations: Ph.petiolatus (Clarke)H.S.Kung et L.B.Zhang, Ph. cryptomerianus (Maxim.)Ching, Ph. ovatifolius (Ching)W.M.Chu, Ph. nylamensis (Ching et S.K.Wu)H.S.Kung et L.B.Zhang; and 7 names are considered for the first time as synonyms: Huperzia formosana Holub [=Ph. taiwanensis Ching], H.austrosinica Ching Ph. petiolatus], Lycopodium mingchgense Ching [=Ph. mincheensis Ching], Ph. mincheensis var. angustifolius C.Y.Ma Ph. mincheensis], Ph. longyangensis C.Y.Ma Ph.fordii], Ph.nanus C.Y.Ma Ph.fordii], Ph.yandongensis Ching et C.F.Zhang Ph.fordii]. One new record in China is found: Ph.hamiltonii.
