Recently, the Chengdu Institute of Biology of the Chinese Academy of Sciences and the research staff of Jiangxi Agricultural University published a paper published in the ecological journal "Ecosystem Health and Sustainability", which introduced a new Rats and Plants (Latin scientific name: Colubrina Zhaoguangii). At the same time, the researchers also discussed their close relationship with the syndrome of molecularly in accordance with the characteristics of the flowers and fruits, and according to the distribution range, number of plants, and interference of the distribution, the number of plants, and the degree of disturbances of the gradous. Dangerous species.

This is the third type of snake vine recorded by China. The other two types of snake vines distributed in my country are snake vines and wool snake vines. The former is distributed in the coastal areas in Guangdong, Guangxi, and Taiwan, and the latter is distributed in the Lancang River and Honghe of the southern Yunnan.

The discovery of the "Relief Valley Snake Vine" is in the dry warm river valley in the Jinsha River Basin.

In August 2021, Dr. Hu Jun, the Chengdu Institute of Biology of the Chinese Academy of Sciences, led the inspection team to the second Qinghai -Tibet Plateau scientific investigation during the Qinghai -Tibet Plateau in the Jinsha River, Sichuan, Sichuan Province, and collected a rat Like species in the Qinghai -Tibet Plateau Existing rats and plums. After being taught Dr. Yangyi, Jiangxi Agricultural University, compared with domestic and foreign rats at home and abroad, it was confirmed that it was a new species of Rats and Snake Vine.

Researchers have found that compared with snake vines and wool snake vines, the rolling Valley snake vines are short shrubs, and the top of the branches is often specialized into thorn, and the leaves are small and the top is short, so it is easy to identify. In terms of form, the Relief Valley Vine and Madagascar's Madagascar Snake Vine and the green snake vine in northwestern Mexico are very similar, but there are tiny white bubble -shaped scales on the leaves of the Relief Valley snake vine.

The reason why its Latin scientific name is planned to be Colubrina Zhaoguangii is to commemorate and pay tribute to researchers Liu Zhaoguang, an alleged botanist and ecologist who has long been engaged in vegetation research in Hengduan Mountain. Liu Zhaoguang is known as the "Son of Dashan". The editor -in -chief of "Sichuan Vegetation" came out in the early 1980s, filling the gap in vegetation research in the large plant provinces of western China. Essential information.

Researchers said that the discovery of the Valley snake vine not only enriched the diversity of plant species in my country, but also highlighted the importance of the basic investigation of biodiversity. In addition, the discovery and publication of the Royal Valley snake vine have important scientific value for studying the system development of rats and biological geography in Hengduan Mountains.

In addition, according to the distribution range, number of plants, and degree of disturbances of the Royal Valley snake vine, they are advised to evaluate the Relief Valley vine species of dangerous (VU) species.
