The complete chloroplast genome sequence of <i>Hydrocotyle vulgaris</i> L. (Araliaceae)

<i>Hydrocotyle vulgaris</i> is a perennial wetland clonal plant in the Araliaceae family, which was introduced to China as an ornamental plant in the 1990s. Although <i>H. vulgaris</i> is now considered a potential invasiveness species in China, it also plays a significant role in the remediation of water pollution. Here, we reported its complete chloroplast genome and analyzed the basic characteristics. The chloroplast genome was 153,165 bp in length, including a pair of inverted repeat (IR) regions of 25,072 bp separated by a large single-copy (LSC) region of 84,291 bp and a small single-copy (SSC) region of 18,730 bp. The <i>H. vulgaris</i> chloroplast genome contained 132 predicted genes, and its overall GC content was 37.60%. Phylogenetic analysis revealed that <i>H. vulgaris</i> was closely related to <i>H. verticillata</i>. The <i>H. vulgaris</i> chloroplast genome presented in this study will lay a foundation for further genetic and genomic studies of the genus <i>Hydrocotyle</i>.
