(DC.) H.S. Irwin & Barneby is a popular ornamental tree as well as a traditional medical plant in Cameroon. In this study, we sequenced and annotated the complete chloroplast genome of and reconstructed the phylogenetic relationship of the tribe Cassieae. The length of the chloroplast genome was determined to be 162,754 bp, containing a pair of inverted repeats of 25,413 bp which separated by a small single-copy (SSC) region of 20,161 bp and a large single-copy (LSC) region of 91,767 bp. The cp genome encodes 128 genes, including 83 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The percentage of total GC content of this genome was 35.7%. The phylogenetic analysis indicates that with the sampled species formed a well-supported monophyletic clade.
（DC.）欧文氏苏木和巴恩比苏木是喀麦隆一种受欢迎的观赏树以及传统药用植物。在本研究中，我们对其完整叶绿体基因组进行了测序和注释，并重建了决明族的系统发育关系。叶绿体基因组长度确定为162,754 bp，包含一对25,413 bp的反向重复序列，由一个20,161 bp的小单拷贝（SSC）区域和一个91,767 bp的大单拷贝（LSC）区域隔开。叶绿体基因组编码128个基因，包括83个蛋白质编码基因、37个tRNA基因和8个rRNA基因。该基因组的总GC含量百分比为35.7%。系统发育分析表明，所研究物种与采样的决明属物种形成了一个得到充分支持的单系分支。
