Summary of the grammitid ferns (Grammitidoideae, Polypodiaceae) diversity of China (Chinese species printed in bold). Columns report: "Genus" recorded genera according to PPG 1 (2016); "Species" recorded species occurring in China according to the most recent publications; "2000" species reported in Zhang (2000); "2013" species recorded in Zhang et al. (2013); "2016" species recorded in Yan et al. (2016); "2017" species recorded in Yan et al. (2016) plus Knapp and Hsu (2017) ; "TaxCon" consistency of species names used in the different taxonomic records (CO = same name used throughout, MI = misapplied species names in older treatments, NA = not applicable; SY = synonyms used in older publications); "PhyRes" species represented in the rbcL dataset (0 = absent, 1 = present)). The following columns report present (1) or absence (0) in Chinese provinces with grammitid records. ChPrSp reports the number of provinces in which each grammitid species has been recorded. The final column "Vietnam" reports occurrences in Vietnam.
