The complete chloroplast genome of <i>Keteleeria evelyniana</i> Mast var. <i>pendula</i> Hsüeh (Pinaceae), a species with extremely small populations in China

<i>Keteleeria evelyniana</i> Mast var. <i>pendula</i> Hsüeh, a typical plant species of extremely small population, is faced to be endangered. The complete chloroplast (cp) genome of <i>K. evelyniana</i> var. <i>pendula</i> has been assembled and annotated for the first time in this study. The complete genome in length was found to be 117,139 bp. The genome annotation revealed a total of 118 genes, including 34 transfer RNA (tRNA) genes, 4 ribosomal RNA (rRNA) genes, and 80 protein-coding genes. The maximum-likelihood phylogenetic tree supported that <i>K. evelyniana</i> var. <i>pendula</i>, <i>K. fortune</i>, <i>K. evelyniana</i>, and <i>K. davidiana</i> are clustered in one branch. This complete chloroplast genome helped us to understand the evolution of <i>K. evelyniana</i> var. <i>pendula</i>. These results laid the foundation for future studies on the conservation of this species.
