According to the Chengdu Institute of Biology under the Chinese Academy of Sciences (CAS), researchers have rediscovered a critically endangered plant, Euonymus aquifolium, during China's second scientific research survey on the Qinghai-Tibet Plateau.

Euonymus aquifolium is a rare and vegetatively distinctive species, and the rediscovery by Chinese researchers uncovered the only presently confirmed living individuals more than 110 years after a single gathering collected by British scientist E.H. Wilson in 1908, according to a research article published in the journal PhytoKeys.

"I was lucky. Some experts have been looking for it for more than a decade, and some even fell down mountains during the expedition, but to no avail." said Hu Jun, assistant researcher of the institute.
