Abstract
The genus Petrocodon is uniquely distributed in karst areas and exhibits high floral morphological diversity. We assembled and characterized the complete chloroplast genomes of Petrocodon mirus X.Z.Shi, J.X.Fu & L.H.Yang 2024 and Petrocodon hancei (Hemsl. 1890) A.Weber & Mich.Möller 2011. The genome sizes are 153,547 bp and 153,294 bp, respectively. Phylogenetic analysis revealed that P. hancei is closely related to P. multiflorus, while the position of P. mirus remains unclear. These findings provide genomic resources for studying genetic diversity in Petrocodon and Gesneriaceae.
