A new species of Clematis L. (Ranunculaceae), C. liuzhouensis Y. G. Wei & C. R. Lin, is described and illustrated. The new species is related to C. wissmanniana Handel-Mazzetti, but differs in its leaflets that always have entire margins and are abaxially silvery-pannose and in its smaller sepals that are up to 1.5 × 0.6 cm.
