Complete chloroplast genomes analysis of Lamium barbatum and Leucas ciliata (Lamiaceae)

The two Lamioideae species, Lamium barbatum Siebold & Zucc. 1846, is distributed across Europe, North Africa, Asia, and North America, while Leucas ciliata Hochst. ex Benth. 1829 is found in southern China and Southeast Asia. We sequenced their complete chloroplast genomes using the Illumina platform, obtaining lengths of 150,887 bp and 151,259 bp, respectively. Phylogenetic analysis showed Lamium barbatum is closely related to four other Lamium species, including Lamium takeshimense, Lamium album, Lamium amplexicaule, and Lamium galeobdolon. The Leucas ciliata species clusters with Leucas mollissima. These findings provide valuable data for species identification, evolutionary research, and conservation genetics.
