Passiflora xishuangbannaensis has only been known to the scientific community since 2005. It is a passion flower vine endemic to Yunnan and only found within Xishuangbanna.

Passiflora xishuangbannaensis 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 abaxial laminar nectaries. 

Passiflora xishuangbannaensis reintroduced to the wild

During a field survey in 2015, fewer than 100 individuals were found by XTBG researchers. Their habits are under human disturbance. Its conservation status was considered as critically endangered. 

XTBG researchers prepare for reintroducing Passiflora xishuangbannaensis to the wild at Mengyang.

To protect the passion flower vine, XTBG researchers propagated Passiflora xishuangbannaensis and have got 200 individuals.  

60 individuals were reintroduced to the wild on August 21. XTBG will carry out further monitoring and study to get a high ratio of reintroduction success.
