Plants of the lycophyte genus Phlegmariurus contain the chemical compound Huperzine A, the effective medicinal component treating Alzheimer’s disease, thus with huge economic value. To protect the natural resources, plants of the whole genus are listed as the National Key Protected Wild plants in China. In this paper, we revised the taxonomy of Phlegmariurus distributed in China based on morphological, ecological, and geographical evidence. We recognized 21 species from China, and organized them into four sections. Sect. Fargesiani X. C. Zhang ＆ R. H. Jiang is newly established, and the other three sections were revised based on previous studies, i.e., Sect. Hamiltoniani C. Y. Yang, emend. X. C. Zhang ＆ R. H. Jiang; Sect. Phlegmariurus; and Sect. Squarrosurus（Herter） X. C. Zhang ＆ R. H. Jiang, comb. ＆ stat. nov. We reduced the following taxon names to synonymies of various species of Phlegmariurus: Huperzia medogensis, Phlegmariurus austrosinicus, P. changii, P. nylamensis, P. cancellatus var. minor, P. qiongzhongensis, and P. shangsiensis.

A taxonomic study of the genus Anemone (Ranunculaceae) of China has been conducted. Eighty-six species are recognized and classified into ten Section. Of them, five section, Rivularidium, Anemonanthea, Himalayicae, Brachycladus and Pleurocarpus, are groups with medium-evolutionary level, and the another five sections, Omalocarpus, Stolonifera, Begoniifolia, Anemonidium and Anemone, are groups with high-evolutionary level. In these ten Sections, Sect. Himalayicae is closely related to Sect. Omalocarpus, Sect. Brachycladus is closely related to Sect. Stolonifera, and the relationships among the other six sections are not yet clear now. A key to sections, Series, species and infraspecific taxa, and literature citations and geographic distributions for all taxa are presented. Records of important specimens studied for each species and illustrations for most species are provided. Two section (Sect. Brachycladus and Pleurocarpus), four series (Ser. Hofengeses and Ser. Jiachaenes under Sect. Stolonifera and Ser.Xingyienses and Ser. Orthcarpae under Sect. Pleurocarpus), thirteen species (A. jiulongensis, A.baizhishanica, A.stenosepala, A.daofuenis, A.ludingensis, A. bomiensis, A. galonglashanica, A.trifoliolata, A. zheduoshanica, A.baoxingensis, A. gonggaensis, A. fugongensis and A.discoideogyna), one subspecies (A. obtusiloba ssp. dolichopoda), and four varieties (A. zheduoshanica var.atropurpurea, A.prattii var. sparsipilifera, A.fugongensis var. linearis Bruhl is elevated to specific rank; A. fulingensis is relagated to a variety under A. Pratti; due to that A. rupestris Hook. f. & Thmos. is an illegitimate later homonym, its specific epithet 'rupestris' is changed as 'neorupestris' in this paper; A.barbulata, long relegated to a variety under A.rivularis, is restored to its previous specific rank; and the reduction of A. demissa var. yunnanensis Franch. to var. demissa, and the reduction of A.oligocarpa Pei to A. delavayi Franch, by H. Handel-Mazzetti in 1939 are accepted in this paper. [ABSTRACT FROM AUTHOR]
