A new species of Clematis sect. Tubulosae (Ranunculaceae) from Zhejiang, East China
Clematis liana sp. nov., a new species of Ranunculaceae from Zhejiang and Anhui Provinces in eastern China, is described and illustrated. This species exhibits similarities in morphological features to C. urticifolia, with which it has a close evolutionary relationship. It is distinguishable by several discrete features, such as habit, reproductive strategy, morphology of cauline ridges, leaflets, bracts, and flowers, calycine color, number of carpels and stamens, length and indumentum of filaments, size of anthers and pollen grains, etc. The complete plastid genome sequence of C. liana sp. nov. comprises 159,759 bp, organized into a quadripartite structure containing two inverted repeat (IR: 31,084 bp each) regions, a small single copy (SSC: 18,135 bp) region, and a large single copy (LSC: 79,456 bp) region. It contains 136 functional, comprising 92 protein-coding, 36 tRNA and 8 rRNA genes.
