What is the significance of the discovery of these new plant species in Yangchun, Guangdong?

When the classified scholars discover and named an unnamed biological species, it is called the new species. So how can I know that this species has not been named?

This first needs to determine which subject it belongs to, and then check the literature and specimen, and confirm that the species we have found are different from all species that have been published in the form, and can be determined as a new species.

To be recognized by the academic community, the new species also needs to be described in the form, specimens specimens and officially published, and it must be in line with international naming regulations. So to publish new species, first of all, you have to understand the classification group related to this new species. Secondly, you have to find the right place, that is, the place where new species may be found.

There is such a city called Guangdong Yangchun. This city is essential for the discovery of new plant varieties. Yangchun, Guangdong is the famous model specimen. According to statistics, as many as 60 plants named after Yangchun's model specimen, as many as 15 plants with "Yangchun" in the name.

In Yangchun, what did scientists discover?

From the perspective of the type, Yangchun's plant mode specimens have participated in the name of about 60 plant scientific names, of which only 10 scientific names are described by Yangchun's plants only in the general meaning of the tea family (broaden, including five wooden family, including five wooden family). Five plant names are described according to the naming of Yangchun's plants. Four scientific names in Dongqingke are described according to Yangchun's plants, and 3 of which are named by Zeng Cangjiang (1928 ~ 1982) of Xiamen University.

Rhododendron leaf tea (also known as Cuckoo Red Mountain Tea), a national first -class protection of wild plants, is the longest species of mountain tea. It is a very valuable resources of tea breeding. It was named after Wei Zhaofen (1934 ~) in the South China Botanical Garden in 1986.

In the small city Yangchun, why frequently become a new specimen of specimens?

As a new type of specimens in the new species, Yangchun has attracted much attention in the Chinese botanical community. So, what is the origin of the pattern specimen? It turns out that when we want to determine and publish the scientific name of a group of creatures, we need to point out the characteristics of this scientific name and the pattern specimens of the concept of classification groups. These patterns of the pattern specimens for naming are called mode origin.

The famous Chinese model specimens are Fujian Wuyi Mountain and Baoxing, Sichuan. Because Chinese plant classification starts late, these two places are mainly for foreign people to inspect and collect them here. Therefore, most of these species are named by foreigners. Most of the specimens are preserved in Western countries, which can bring a lot of trouble to Chinese scholars who later studied plant classification. Earlier Chinese scholars need to study these Chinese plants and have to go abroad to see the model specimen.

As a result, the first generation of modern Chinese plant classified scholars represented by Academician Chen Huanzheng (1890 ~ ​​1971), the founder of South China Botanical Garden, set up "China must have its own plant research team, and the Chinese have to study Chinese plants" by themselves ". Massive.

And Yangchun, Guangdong, is such a place to witness Chinese plant classification scholars realize their dreams. At that time, in Yangchun, Guangdong, foreigners were hardly involved. They were mainly collected by the Chinese here. Most of the scientific names were also named by Chinese scholars. Simagonians of the South China Botanical Garden of the Academy of Sciences.

From the perspective of natural conditions, Yangchun City is located in the southwestern part of Guangdong Province. There are mountains such as Hewei Mountain, Yunwu Mountains, and Tianlu Mountains in the territory. Yangchun is located in the tropical transition zone of the northern edge of the tropical. The average annual temperature is as high as 22.1 degrees Celsius. The rainfall period is long and the rainfall is large. The average annual rainfall is about 3429 mm. It is the center of rainfall in Guangdong.

Some plants with strong tropical properties are distributed in the northern boundary of blood sealing throat, pork cage grass, hanging pens, polyxuki, beef tendons, etc., in Yangchun. The most famous plant in Yangchun is "Yangchun Amomum", and the plants are called amomum. They are usually called "spring sand" and are one of the four major southern medicines in China. Because Yangchun is the authentic place of amomum, it is known as "Yangchun Amomum".

In 2003, according to the preliminary statistics of scientific researchers such as Wang Fuguo (1978 ~) in South China Botanical Garden, there were more than 1,580 types of vascular plants in the Yangchun Penguin Phoenix Nature Reserve. However, the survey of Yangchun's plants is still incomplete. Due to the complex terrain and the blooming time of tropical plants, many areas have not been investigated. The new plant and new distribution records of Yangchun are still being discovered. Yangchun, the epitome of the development of modern Chinese plant classification

Yangchun, Guangdong has witnessed the development history of modern Chinese plant classification. my country's modern plant classification began in the 190s and 20th of the last century.

Mr. Zhong Guanguang (1868 ~ 1940) of Peking University is one of the earliest scholars in my country to carry out plant scientific investigations. He first got a small number of specimens involved in Yangchun in November 1918. However, these specimens did not involve scientific names. It is currently preserved in the specimen hall of the Chinese Academy of Sciences and the Peking University specimen hall.

Huang Zhi, the National Institute of Agriculture and Forestry and Forestry of the National Sun Yat -sen University (formerly the South China Botanical Garden), was the first collector to conduct large -scale plant inspections in Yangchun. From 1933 to 1957, Huang Zhi collected a large number of specimens in Yangchun. These specimens are currently kept in the South China Botanical Garden specimen, including 20 scientific name specimens.

One of the Palm plant specimens was given to German botanist Burret, and Burret published a short -axis saving vine in 1937. In 1935, Huang Zhi collected in Yangchun's bean -based plant specimen, and in 1938, Chen Xiuying published it as a pattern specimen of twin sheep hoofs.

The specimen collected by Huang Zhi in Yangchun also includes famous plants such as Hu Yanhua, Yangchun and Winter, Yangchun Rat, and flat fruit Runnan. To commemorate Huang Zhi's contribution, the plant names named after his name include: Acer Wangchii, Machilus Wangchiana, and Tarenna Wangii.

Since the collection of large -scale plants in Yangchun has been started very early, the South China Botanical Garden has also become the earliest scientific research institutions to carry out the research of Yangchun plant research and published the most new Yangchun plant species. Among them, there are as many as 21 new species of Yangchun plant participating and named Yangchun.

In 1953, Chen Huanzheng of the South China Botanical Garden named Bian Guo Nunnan. In 1952, He Chunnian (1906 ~ 1968) participated in the publication of the small flowers and trees. Essence In 1982, Tan Peixiang (1919 ~ 1991) named the waxy yellow cuckoo. In 1983, Luo Xianrui (1927 ~ 2000) named Shisheng snail order grass. In 2013, Qiu Huaxing (1929 ~) published Yangchun Mountain Longan and so on.

Li Bingtao of South China Agricultural University (1936 ~) published a hidden vein bead bead, and Xu Xianghao (1920 ~ 2017) named the swelling tube jade leaf Jinhua.

In 1998, Professor Lin Laiguan (1925 ~ 2014) of Fujian Normal University (1925 ~ 2014) was named Yangchun Hongsang ratio based on the mode specimen collected by the South China Institute of Botanical Research (Garden) in 1957.

Found new plant species, maybe you are the next

Due to the incomplete investigation of Yangchun's plants, new plant species or new records have been discovered in recent years. For example, Guangdong Changshan is a new species published in 2018. Shield leaves and oblique eaves are published in 2019. The new species, thick -petal eagle claw flowers were published in 2021, all of which are unique to Yangchun narrow domains. It is said that there are two new species from Yangchun being submitted and have not yet been officially published.

The new specimens of the new species in the new period are usually newly discovered and collected. Often the collector directly participated in the species name, such as Ye Huagu (1956 ~) of the South China Botanical Garden to participate in the collection and named Yangchun. The two species were published in cooperation with Xing Fuwu (1956 ~). Wang Ruijiang (1968 ~) participated in the collection and named Yangchun snail order in 2016. Zheng Yongli (1976 ~) and Deng Yunfei (1970 ~) cooperated to publish Yangchun Spring moss.

Zeng Sijin of South China Agricultural University (1989 ~) participated in the collection and named Zhuang's alien flower in 2016. Huang Gezi (1992 ~) and Hao Gang (1966 ~) participated in the collection and named Guangdong Changshan in 2018. Zhou Xinxin (1980 ~) of the South China Botanical Garden participated in the collection and named the oblique eaves Guanmutong in 2019.

Liao Wenbo, Sun Yat -sen University, and others named Goose Phoenix Qiuqiu Begonia in 2018. Liu Ying (1982 ~) participated in the collection and named Kikuchi plant shields in 2019. 1964 ~).

Shield Ye Pu Ergen (Photo by Chen Yousheng, Xu Yichun) The recent new species is the thick petlays of the Fan Litchi family. Naming the specimen.

There are quite a lot of limestone areas in Yangchun. New species published in recent years, such as oblique eaves, Guanmutong, Yangchun snail order grass, Yangchun quantity grass, goose phoenix autumn begonia, Guangdong begonia, thick petlays, and several bitter moss fur The plants were found in the limestone area of ​​Yangchun.

Among them, the heart column reported the spring moss and the specimen was found and collected in the wild by plant lovers Wang Bingmou (1984 ~), and then published it with the Kwar Moss Association of the Bitterius Department of the Guangxi Plant Research Institute in 2016. Therefore, if you are also a plant enthusiast, it is also possible to participate in the publication of new species.

Because of love, I choose to adhere to and inherit

From the first generation of plant collectors (bell tourism) in China, to the second -generation collector (Huang Zhi, Liang Xiangri) from the Republic of China to the early years of the founding period, to the early 21st century ), Now it is mainly collected by botanists to carry out specialized colleges (such as Zeng Sijin, Liu Ying, Wen Fang, etc.). The adherence and inheritance of plant classification scholars. These scholars are mainly from the Lingnan region, most of which come from the South China Botanical Garden of the Chinese Academy of Sciences.

The history of plant research in Yangchun has witnessed the development of plant classification in the Lingnan area, and also witnessed the development of the South China Botanical Garden. The study of plant classification was passed down from the salary of classified scholars in different periods that it has obtained the current grand occasion of plant classification research. It also realizes the dream of "Chinese people study botanicals and named plants" more than a century ago. Essence
