Abstract: Corydalis DC.is a largest genus in the family Fumariaceae, and large one of those that are distributed in North Temperate. Since this genus was established there has been no complete classification system and there have been a lot of disputes even in the nominator of the genus, the generic lectotype, subgeneric classifiction and so on. According to the study and arrangement of the type specimens or authentic materials from China and neighbouring countries of both S. & E. Asia and kept in both Chinese herbaria and important herbaria abroad, this paper has for the first time classified this genus into two groups, i.e. Corydalis and Pistolochia, and 40 sections that have constituted a complete and original evolutional systom.

Key words: Corydalis, Systematic evolution, Florogenesis, Floristic regionalization

摘要： 紫堇属 Corydalis DC.是紫堇科 Fumariaceae 的最大属，也是北温带分布类型的大属之一。本属自建立以来，迄今尚无完整的分类系统，甚至连属的命名人、后选属模式以及属下分类单位的划分均存在许多争议，本文根据作者们二十多年来在国内外有关标本室收集的模式标本和有关东亚、南亚标本，经过鉴定整理，首次将本属划分为两大类群，即Corydalis群和Pistolochia群和40个组，并初步建立了一个较全而新的进化系统。
