(Forssk.) Brownsey & Jermy (Thelypteridaceae) is endemic to the tropical and subtropical regions of Africa, Asia, and Asia Pacific. In this study, the complete chloroplast genome sequence of was assembled using next-generation sequencing data. The complete chloroplast genome was 151,662 bp in length and had a typical quadripartite structure, which consisted of a small single-copy region (21,776 bp) and a large single-copy region (82,624 bp) that were separated by a pair of inverted repeats (23,631 bp each). A total of 131 genes were predicted, including 89 protein coding (CDS), 34 tRNA, and eight rRNA genes. The overall GC content of the chloroplast genome was 42.48%. Based on the concatenated shared unique CDS sequence dataset, phylogenetic analysis using both the maximum-likelihood and the Bayesian inference methods revealed that is placed within Thelypteridaceae and is closely related to . Such genetic information would be useful for studies on the evolution pattern in ferns. The availability of chloroplast genome sequence for the species also paves the way to resolving the complicated relationship among members of .
（福斯克）布朗西和杰米（金星蕨科）是非洲、亚洲和亚太地区热带和亚热带地区特有的。在本研究中，利用二代测序数据组装了该物种的完整叶绿体基因组序列。完整的叶绿体基因组长度为151,662 bp，具有典型的四分体结构，由一个小单拷贝区域（21,776 bp）和一个大单拷贝区域（82,624 bp）组成，这两个区域被一对反向重复序列（各23,631 bp）隔开。共预测到131个基因，包括89个蛋白质编码基因（CDS）、34个tRNA基因和8个rRNA基因。叶绿体基因组的总体GC含量为42.48%。基于串联的共享独特CDS序列数据集，使用最大似然法和贝叶斯推断法进行的系统发育分析表明，该物种位于金星蕨科内，并且与……密切相关。这些遗传信息将有助于蕨类植物进化模式的研究。该物种叶绿体基因组序列的可得性也为解决……成员之间复杂的关系铺平了道路。
