The present work proposes, for the first time, a study exclusively focused on the diversity of Pteridophytes in Togo.The study was based on fieldwork that resulted in 869 new collections gathered between 2013 and 2017 in the country and on yet existing herbarium specimens kept at the Herbaria of Lomé and Paris. Thus, a total number of 1092 specimens collected throughout the country served as a basis for this work, to which were added the known, published occurrences of Pteridophytes for the country.
At the end of this study, a total diversity of 134 species belonging to 53 genera and 25 families and 12 orders were recorded and documented for the country. It results in 73 newly cited species for Togolese flora, including 61 spontaneous species. Lycopodiopsida (18 species) and Polypodiopsida (116 species) classes are both represented. The Polypodiales order is the most represented with 97 species. The Pteridaceae and Aspleniaceae families are the most diverse with 24 and 22 species respectively. Finally, notes were provided on species distribution at national level.
本研究首次提出一项专门针对多哥蕨类植物多样性的研究。该研究基于2013年至2017年期间在该国进行的实地考察所收集的869份新标本，以及保存在洛美和巴黎植物标本馆的现有标本。因此，全国共收集的1092份标本为本研究提供了基础，并补充了该国已知的、已发表的蕨类植物出现情况。
在本研究结束时，记录并整理了该国134种蕨类植物的多样性，分属于53个属、25个科和12个目。这为多哥植物区系新增了73个物种记录，其中包括61个野生种。石松纲（18种）和水龙骨纲（116种）均有代表。水龙骨目种类最多，有97种。凤尾蕨科和铁角蕨科最为多样，分别有24种和22种。最后，给出了这些物种在国家层面的分布情况说明。
