Background/Objectives: Polygonatum grandicaule Y.S.Kim, B.U.Oh & C.G.Jang (Asparagaceae Juss.), a Korean endemic species, has been described based on its erect stem, tubular perianth shape, and pedicel length. However, taxonomic status remains unclear due to limited molecular data. Methods: This study presents the complete plastid genomes (plastomes) of two P. individuals close relative, odoratum (Mill.) Druce var. thunbergii (C.Morren Decne.) H.Hara. Results: The plastomes, ranging from 154,578 154,579 base pairs (bp), are identical those falcatum A.Gray, odoratum, another infundiflorum C.G.Jang. All contain 78 protein-coding genes (PCGs), 30 tRNA genes, four rRNA except for pseudogene infA. Phylogenetic analyses using PCGs whole intergenic spacer (IGS) regions strongly support three sections within Mill. show that variety nested falcatum, grandicaule, infundiflorum. Conclusions: Given genomic variation phylogenetic relationships, we propose treating as part complex, despite their morphological differences. offers valuable putative markers species identification supports application plastome-based super-barcoding in morphologically diverse genus Polygonatum.
