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

## TL;DR

This paper analyzes the complete chloroplast genomes of two Lamiaceae species to understand their evolutionary relationships and provide data for conservation.

## Contribution

The study provides new complete chloroplast genome sequences for Lamium barbatum and Leucas ciliata, enhancing phylogenetic understanding.

## Key findings

- Lamium barbatum is closely related to four other Lamium species based on chloroplast genome analysis.
- Leucas ciliata clusters with Leucas mollissima in the phylogenetic analysis.
- The chloroplast genome sequences are valuable for species identification and evolutionary research.

## Abstract

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.
