Passiflora xishuangbannaensis, a new species endemic to Yunnan Province, China, is described and illustrated. It is distinguished from other members of Passiflora supersection Disemma by being completely glabrous, having one to two flowers per node, thickened coronal filaments that are brown to purple at the base, deeply bilobed leaves with strong variegation along the three primary veins, and a v-shaped arrangement of numerous ab-axial laminar nectaries.
