[Objective] Corydalis , a large genus of Papaveraceae, is considered one of the most challenging groups in taxonomy. The classification of Corydalis in Henan remains unclear due to insufficient exploration of taxonomic characteristics and a lack of thorough revisions. [Methods] After reviewing the original literature and specimens from the Chinese Virtual Herbarium (CVH),we conducted field investigations, took photos and collected specimens. [Results] We confirmed three newly recorded species of Corydalis species in Henan Province, namely C. nanwutaishanensis Z.Y. Su & Lidén, C. ochotensis Turcz. and C. wilfordii Regel. We also verified that C. shaanxiensis Lidén ex C. Y. Wu, H. Chuang & Z. Y. Su and C. micrantha (Steph.) Pers. were misidentified as C. curviflora Maxim. and C. humosa Migo. in previous literature. In addition, we found a translation error in the label of C. pseudoincisa C.Y.Wu, Z.Y.Su & Lidén, which might not occur in Henan. [Conclusion] This study can be used to provide data for the study of biodiversity science in Henan and the revision of Flora of Henan.
