() and var. are invasive taxa introduced in the Chinese mainland in the 19th century. has been listed in the list of highly invasive species in China, which has seriously endangered the growth and reproduction of local species. As a poisonous plant, var. , a variant of , will also endanger the safety of animals. We report the complete chloroplast genome sequence of and var. . The chloroplast genome of is 164,450 bp long and the chloroplast genome of var. is 164,445 bp long. Both and var. contain a large single-copy region (LSC) of 89,807 bp and a small single-copy (SSC) region of 18,728 bp. The overall GC content of the two species is both 37.45%. A total of 84 genes were annotated in the two species, namely 54 protein-coding genes, 29 tRNA genes, and one rRNA gene. The phylogenetic tree based on the chloroplast genome of 22 related species showed that var. is most closely related to , while the latter clade is sister to and . Our data provide a theoretical basis for the molecular identification, genetic relationships, and invasion risk monitoring of and var. .
（）和变种是19世纪引入中国大陆的入侵类群。已被列入中国高度入侵物种名单，严重危及当地物种的生长和繁殖。作为一种有毒植物，变种作为的一个变种，也会危及动物安全。我们报道了和变种的完整叶绿体基因组序列。的叶绿体基因组长度为164,450 bp，变种的叶绿体基因组长度为164,445 bp。和变种均包含一个89,807 bp的大单拷贝区域（LSC）和一个18,728 bp的小单拷贝（SSC）区域。这两个物种的总体GC含量均为37.45%。在这两个物种中共注释了84个基因，即54个蛋白质编码基因、29个tRNA基因和1个rRNA基因。基于22个相关物种叶绿体基因组的系统发育树表明，变种与关系最为密切，而后者的分支是和的姐妹分支。我们的数据为和变种的分子鉴定、遗传关系及入侵风险监测提供了理论依据。
