is a diffuse shrub belonging to sect. . It is endemic to Southwest China and of high ornamental and economic value. However, its systematic position remains unclear. Here, the complete chloroplast genome of . was assembled using high-throughput sequencing data. The cp genome is 157,064 bp in length with a large single-copy region (LSC) of 86,216 bp, a small single-copy region (SSC) of 18,752 bp, and a pair of inverted repeats (IRs) of 26,048 bp. The overall GC content is 37.2%. A total of 137 genes were annotated, including 90 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis revealed that . is closely related to . of . sect. rather than species of . sect. .
是一种属于……组的蔓生灌木。它是中国西南地区的特有植物，具有很高的观赏和经济价值。然而，其系统位置仍不明确。在此，利用高通量测序数据组装了……的完整叶绿体基因组。叶绿体基因组长度为157,064 bp，其中大单拷贝区域（LSC）为86,216 bp，小单拷贝区域（SSC）为18,752 bp，一对反向重复序列（IRs）为26,048 bp。总体GC含量为37.2%。共注释了137个基因，包括90个蛋白质编码基因、37个tRNA基因和8个rRNA基因。系统发育分析表明，……与……组的……关系密切，而非……组的物种。
