The complete chloroplast genome of <i>Corydalis wilsonii</i> N. E. Brown 1903 and its phylogenetic analysis

Species within <i>Corydalis</i> are valued for medicinal and ornamental uses but taxonomic uncertainties persist due to limited genomic data. Here, we present the complete chloroplast genome of <i>C. wilsonii</i>, with a quadripartite structure of 191,388 bp and 140 functional genes. Phylogenetic analysis robustly resolves <i>C. wilsonii</i> within a monophyletic clade alongside <i>C. saxicola</i>, <i>C. tomentella</i>, and <i>C. fangshanensis</i>, all nested within sect. <i>Thalictrifoliae</i> (bootstrap support = 100%). This study expands the chloroplast genomic resources for <i>Corydalis</i> and establishes a taxonomic framework to refine species identification and resolve evolutionary relationships within this ecologically and economically vital genus.
