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.
During the scientific expedition along the southeastern slope of Mt. Gongga, 15 individuals of Euonymus aquifolium were unexpectedly encountered by Hu Jun and his team members in August 2021.
