Xu Anqing stood up on a stone and saw more than twenty meters away, Yang Rui was spinning around a low plant. At some point, a camera was hung around his neck.

Xie Gaoyi walked over with some amusement. When he looked at Yang Rui, he was still thinking in his heart that he was still a young man.

Discovering new species is not that easy. A plant taxonomist discovered only three or four or five new species in his life.

And how many field surveys a professional plant taxonomist should do in his life? There must be eight hundred without a thousand.

It is not impossible to achieve something in the first field survey, but the probability is too low.

Being a plant taxonomist is different from ordinary scholars. Plant taxonomists do not accumulate enough knowledge to find new species, and they also have the opportunity to face the new species.

Xie Gaoyi is also a man who has discovered a new species. He knows how low the chance of this is. Moreover, he has really heard of too many similar problems:

"Teacher, I think I may have discovered a new species." This kind of child is the stupidest, but when investigating in the wild, the wild students are basically like this bird.

"Teacher, see what species this is." This kind of child is more well-behaved, but the ending will not change at all because of well-behaved.

"Teacher, I found a strange plant." Yang Rui said this. However, the keen Professor Xie could hear the subtext in it at the first ear. The problem is, in the eyes of Professor Xie, the strange plant, is completely normal.

Xie Gaoyi deliberately waited for Yang Rui to finish taking the photo and was about to collect the specimens before standing over, looking down, and comparing with the species in his mind, saying, "It seems that it is from the genus Blue Sprig."

He has come to Badaling Forest Area for many times, and he is very familiar with the distribution of plants in the forest area. In fact, some research work itself is to distribute plants in various forest areas.

For example, for the genus Blue Thorn, botanists know that genus Blue Thorn is about 100 more than 100 in the world, and is distributed in China, from northwest to northeast. If you don’t have such an understanding, Xie Gaoyi would not dare to say that it is the genus Blue Thorn. It’s like you see a tree that looks like a coconut tree growing in the wild in Heilongjiang at minus 40 degrees below the sea, and is competing for living space with a group of coniferous forests. Do you dare to recognize it as a coconut tree? Let’s talk about the winning rate of alien plants.

After confirming that it was a plant of the genus Blue Thorn, Xie Gaoyi felt a little more relaxed. This cannot be said to be the taxon he is good at, but it also belongs to a very familiar taxon.

According to the decreasing law of species of the family genus of the Jiemen, Xie Gaoyi began to make a detailed judgment. At the same time, as a teaching task, Xie Gaoyi still had time to introduce to the students: "The species of the Blue Thorns are all thick herbs, usually perennial, and biennial, with very few annuals. Look at the upper part of its stems, there are branches and small fine hairs. These are the characteristics of the Blue Thorns. After confirming these, let's look at the leaves...the leaves are generally smooth edges..."

Speaking of this, Xie Gaoyi stopped because it was obvious that the edges of the Blue Thorns herb found by Yang Rui were not smooth.

Xie Gaoyi hesitated for a moment, but did not worry about this, and said, "There are also rough edges, which are relatively rare. Well, let's look at the top of its stems and branches. For half of the time, there are extremely small braced leaves on the periphery, usually one to two layers... Well, this one has... three layers."

Xie Gaoyi couldn't help but look up, glanced at Yang Rui in surprise, and then looked down. This time, he didn't speak anymore, but just tossed the small herbs over and over again, like a wild dog rummaging over and over again.

After a while, Xie Gaoyi said: "For the specific species of this plant of the genus Blue Thorn, we have to go back and compare the literature to determine the specimen. This is also what everyone will learn in the future..."

Botanists are naturally experienced in plants, but it is impossible to know the full characteristics of each flower and plant.

Of course, common species in cities or local suburbs can be seen at a glance, but that is because there are few varieties of C plants in cities and suburbs. When you arrive in the forest area, you will have a more test of the characteristics of common species. Naturally, angiosperms such as pine and black pine are still not at all.

However, if you want to go further, it is basically unlikely.

The cumulative number of plants discovered in China has exceeded 31,000. This number is a huge test for the brain capacity of botanists. It is difficult for normal humans to have such IQ. As for scientists with genius super brains - you are all genius high IQs, and you still choose to be a plant taxonomy. Is your head clamped by the door?

"Anyway, collect the specimens first." Xie Gaoyi took a little serious, took out a sketchbook, drew a plant shape, and drew a few strokes of the surrounding scenery, and taught Yang Rui to record the surrounding addresses.

Yang Rui is extremely skillful.

He had just searched in his mind for a long time, but he was just looking for an address.

The discovery of new species must be clearly explained where it was discovered. Is it a new species on the bottom of the sea, or a miracle corner like a normal person who would not climb, or is it in basins, plateaus, rivers, and saline-alkali land?

The specific location is not missing, especially in places like Badaling Forest, where students and teachers who are surveyed in the wild are gone everywhere and you have found a suspected new species. You must record it clearly. Maybe you can go back and turn over the specimen cabinet and see similar specimens collected by your predecessors. In this way, directly checking the conclusions of your predecessors can save a lot of trouble.

Moreover, there is another type of botanist who specializes in checking specimens to determine whether the specimens are new species, or whether they are new distribution areas, etc., which are also similar to chain research systems.

In front of Yang Rui, Xie Gaoyi naturally had to complete all the steps meticulously, and half-teached Yang Rui to collect the specimens before getting up and stamping his feet, saying, "Let's just spread out and look for similar plants nearby. Generally speaking, the distribution of new species is relatively concentrated."

The students obediently dispersed. Xu Anqing came to Professor Xie with a strange expression and said, "Professor Xie, it cannot be a real new species."

He felt that Professor Xie might have made such a decision to please Yang Rui. However, why did the Peking University professor please a student of Yang Rui? The answer to this question was something he was unwilling to accept.

Not to mention Xu Anqing himself, even if his father comes with a general-level epaulette, there is no need to please the Peking University professors.

Professor Xie did not expect that Xu Anqing had this kind of mind now. If he knew, he would probably have to slap him away. At this time, he said lightly: "I'm not sure about the situation of this plant, so I have to take it back to take a look. Of course, it is very likely that it was discovered by our predecessors, but after all, there are some new features."

"Didn't you also say that there are varieties with smooth edges or not?"

"There are no three circles of bracts." Xie Gaoyi answered very surely. The characteristics of plants of a species always have a range. If they exceed the range, it is worth exploring.

For example, a man has eight or nine fingers, and a man with eleven fingers calls himself the Six-fingered Piano Demon. The situation with twelve fingers cannot be said to be strange. However, if someone has fifteen fingers, there is certainly reason to suspect that he is another kind of human.

In fact, many new species discovered in modern times can be called new mutant species. For example, the Six-fingered Piano Demon has a geographical isolation from normal humans. After a long time, it has reproductive isolation, so it is also possible to become a new species, Six-fingered Man.

The scope examples of using your fingers are more broad and more extreme. A normal man has three legs. Will the mutation with four legs appear? - Don't underestimate the natural mutation! If you encounter a monkey with two younger brothers, it is completely worth checking whether it is a new species for taxonomists.

Xu Anqing couldn't help but speak loudly because of strange dissatisfaction, saying, "Professor Xie, your standards are too broad. Yang Rui has never studied plant taxonomy."

Yang Rui answered honestly: "I really haven't learned much."

Professor Xie waved his hand and said, "Discovering new species does not necessarily require you to learn plant taxonomy. Of course, you usually have to learn it before you have a better chance of discovering new species. A botanist has discovered one or two plants in his life, and even new species have not been found. However, there are also people who have found new species. In short, some people are lucky."

"Luck..." Xu Anqing just wanted to find a tree, hit it and die on it, and gave himself to a lucky wolf.
