is a perennial herb of the genus Begonia and is a near endangered species. Traditional morphological delimitation of is sometimes confused with similar species; therefore, further systematic classification is urgently needed. To enrich the genetic information and guide its molecular identification, the complete chloroplast genome of was sequenced and illustrated. The complete chloroplast genome has a total length of 169,589 bp, containing a large single-copy (LSC, 76,057 bp) and a small single-copy region (SSC, 18,320 bp) separated by a pair of inverted repeat (IR, 37,606 bp) regions. The overall GC content is 35.56%. A total of 142 genes were annotated, including 91 protein coding genes, 8 rRNA genes and 43 tRNA genes. Phylogenetic analysis showed that is more closely related to and . This study enriches the genetic information of and contributes to its accurate molecular identification.
是秋海棠属的一种多年生草本植物，是近危物种。传统的形态学界定有时会与相似物种混淆；因此，迫切需要进一步的系统分类。为了丰富其遗传信息并指导其分子鉴定，对其完整的叶绿体基因组进行了测序和阐释。完整的叶绿体基因组全长169,589 bp，包含一个大单拷贝区（LSC，76,057 bp）和一个小单拷贝区（SSC，18,320 bp），由一对反向重复（IR，37,606 bp）区域隔开。总体GC含量为35.56%。共注释了142个基因，包括91个蛋白质编码基因、8个rRNA基因和43个tRNA基因。系统发育分析表明，与和的关系更为密切。本研究丰富了的遗传信息，有助于其准确的分子鉴定。
