Complete chloroplast genomes analysis of <i>Lamium barbatum</i> and <i>Leucas ciliata</i> (Lamiaceae)

The two Lamioideae species, <i>Lamium barbatum</i> Siebold & Zucc. 1846, is distributed across Europe, North Africa, Asia, and North America, while <i>Leucas ciliata</i> 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 <i>Lamium barbatum</i> is closely related to four other <i>Lamium</i> species, including <i>Lamium takeshimense</i>, <i>Lamium album</i>, <i>Lamium amplexicaule</i>, and <i>Lamium galeobdolon</i>. The <i>Leucas ciliata</i> species clusters with <i>Leucas mollissima</i>. These findings provide valuable data for species identification, evolutionary research, and conservation genetics.
