Chen (Iridaceae: subgenus LimnirissectionLophiris) from Chongqing, China, is described and illustrated. This hybrid is morphologically similar to <i>I.japonica</i> Thunb. and <i>I.wattii</i> Baker, but can be distinguished by its giant leaves and large purple flowers. Phylogenetic trees based on cpDNA data support the separation of I.×ampliflora from other closely related species in the section Lophiris. According to its morphological features, molecular systematic evidence and chromosome data, we speculate that I.×ampliflora [31 chromosomes] likely is a new hybrid between <i>I.japonica</i> [2<i>n</i> = 32] and <i>I.wattii</i> [2<i>n</i> = 30].PhytoKeys1-12https://www.ebi.ac.uk/biostudies/studies/S-EPMC9849019biostudies-literatureA new natural hybrid of <i>Iris</i> (Iridaceae) from Chongqing, China.PMC9849019Zhou XFXiao YEYu FYfalseA new natural hybrid of <i>Iris</i> (Iridaceae) from Chongqing, China.A newly discovered natural hybrid, Iris×ampliflora Y.E.
