Clematis danxiacola (Ranunculaceae), a new species from the Danxia landform area in Zhejiang Province, China

<i>Clematis danxiacola</i>, a novel species of Ranunculaceae discovered in the Danxia landform area of Zhejiang, China, is described and illustrated herein. This species exhibits morphological similarities to <i>C. terniflora</i> and <i>C. chinensis</i>, but can be distinguished by specific characteristics, including the indumentum of leaflet blades, sepal apex morphology, stamen and pistil quantities, and achene morphology and dimensions. The plastome of <i>C. danxiacola</i> <b>sp. nov.</b> extends 159,506 bp and contains two inverted repeats of 31,040 bp, separated by a large single-copy region of 82,836 bp and a small single-copy region of 18,407 bp. The analysis revealed 136 functional genes, including 92 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. Phylogenetic analyses demonstrated that <i>C. danxiacola</i> shares close evolutionary relationship with <i>C. terniflora</i> and <i>C. chinensis</i>.
