Abstract: Sect. Benecinctae Fedde ex C.Y. Wu et T.Y. Shu is an alpine-group of genus Corydalis distribting at the adjoining region of Yunnan, Sichuan and Xizang. It is a quite natural group and differs frorn other groups of Corydalis by its own morphological characters. It was established by Fedde in 1928 (Fedde in Fedde Rep. 25:221, 1928) and afterwards fallen under the grade Subsect. Benecinctae Fedde by the same auther and belonging to his Sect. Eucorydalis Fedde (Fedde in Engler et Prantl, Natural Pflanzenfam. 17b: 134, 1936). Owing to Fedde's Section without a Latin description and some new species discovered in recent years have broken the bounds of Fedde's concept of this Section. It is necessary to rebuild the Fedde's Section and to add Latin description amplifying the contents.

Key words: preliminary, genus, sect., benecinctae
