(Dennst.) Nicolson, 1885, often known as elephant foot yam, is a tropical tuber crop that originates from south-east Asia and belongs to the Araceae family. It is known for its high production potential and popularity as a medicinal plant. However, the phylogeny and genes for this species are still unavailable. In this study, the first complete chloroplast genome of was reported and phylogenetic analysis was conducted with Araceae species. The chloroplast genome was 176,258 bp in length with 34.80% overall GC content and includes a large single-copy (LSC) region (93,951 bp), a small single-copy (SSC) region (15,013 bp), and a pair of inverted repeat (IRs) regions (33,647 bp). The chloroplast genome has 130 genes, which include 85 protein-coding genes, 37 tRNA genes, and eight rRNA genes. A maximum-likelihood (ML) phylogenetic analysis indicated that all species formed a single monophyletic clade with a high bootstrap value and was closely related to , , , and . The chloroplast genome reported in this study will be useful for further taxonomic and evolutionary studies of .
（丹斯特）尼科尔森，1885年，通常被称为象脚芋，是一种源自东南亚的热带块茎作物，属于天南星科。它以其高生产潜力和作为药用植物的受欢迎程度而闻名。然而，该物种的系统发育和基因仍然未知。在本研究中，报道了该物种的首个完整叶绿体基因组，并与天南星科物种进行了系统发育分析。叶绿体基因组长度为176,258 bp，总体GC含量为34.80%，包括一个大单拷贝（LSC）区域（93,951 bp）、一个小单拷贝（SSC）区域（15,013 bp）和一对反向重复（IRs）区域（33,647 bp）。叶绿体基因组有130个基因，包括85个蛋白质编码基因、37个tRNA基因和8个rRNA基因。最大似然（ML）系统发育分析表明，所有该物种形成了一个具有高自展值的单系类群，且该物种与其他几个物种密切相关。本研究报道的叶绿体基因组将有助于该物种进一步的分类学和进化研究。
