Please help write a plant search form, how to write a search form for plants

The plant search form is written as follows:

Suqian, Ginkgo, Araucaria, Masson pine, Japanese five-needle pine, Huashan pine, Yunnan pine, metasequoia, fir wood, cedar, black pine, oriental cypress, juniper, juniper, Japanese cypress, cedar, Japanese cedar, Japanese cedar, dragon cypress, Yunnan cypress, podocarpus, Japanese cedar, three-pointed fir, southern yew, money pine.

1. There are long branches and shedding short branches, large branches obliquely spread, irregular rotation, drooping branches, opposite or nearly opposite, leaf interaction countermeasures, pinnate two rows, falling off with budless branchlets in winter, male and female plants. ......Metasequoia.

2. The main branches are oblique, with long and short branches, the leaves are fan-shaped, the long branches are alternate, the short branches are clustered, and the dioecious plants are born. ......Ginkgo.

3. The crown of the tree is tower-shaped, with distinct layers, large branches in rotation, and the leaves are two-type. ......Araucaria.

4. The apex of the leaf is gradually sharpened, and there is a white powder band with a wide green edge on each side of the midrib on the leaf surface, which will meet at the apex. ......Juniper.

5. The bark is green and smooth. The apex is gradually sharpened, the stomata below the leaf surface, and the midrib is raised above. ......Three-pointed fir.

6. The bark is thin and scaly, with aril, and the flesh of the seed support is red or purple. ......Podocarpus.

7. The bark is long and peeling, the inner bark is light red, the large branches are flat, the small branches are nearly whorl, the bracts are brownish-yellow, and the triangle is ovate. ......Fir.

8. There are long and short branches, and the leaves on the twigs are clustered. ......Money pine.

The plant search form is written as follows:

1) Grasp the information mentioned in the traits provided, and modify it to the information that is easy to observe when compiling other interval search tables, and the requirements for "all mention" are relatively high, and it is best to be the same trait of the same organ, for example, "sepal synphysis" refers to the sepal fusion trait, and "capsule tooth fissure" refers to the ripe and cracking traits of capsule fruit.

When I was a beginner, I was able to distinguish two different sentences that belonged to the same type of trait. It is more dependent on daily experience, for example, trees, shrubs, herbs, flowers, flowers, fruits, etc., can distinguish the six major organs.

If you can describe the characteristics of each of them, such as shape, surface hair, etc., you can go a little deeper. Returning to the matter of "all mentioned", we can continue to deduce on this basis.

2) The first set of descriptions in the bifurcation distance search table is based on the characteristics that are easy to distinguish and determine, and the premise is, of course, in the real situation, when the flowers and fruits are complete, it generally does not matter which one to choose, the important thing is to be able to clearly divide the two, and special cases need to be considered, for example, "sepals are separated and combined" is best used when the sepals are only completely separated and completely synphytic in the taxa.

When the lowest part of the sepal is combined, it is necessary to merge this category into a group of sepal synphysis, which is used to write the second group of characteristics, because relatively speaking, when there are flowers, it can be distinguished at a glance, and it is better to use "petal tooth fissure or fissure two deep fissures" based on 5 petals (common traits of caryophyllaceae) is also very useful, usually the two deep lobes are almost completely lobed, like the situation of 10 petals.

A trait that is more pronounced but not distinctly dichotomous than one with lobes at the margins depends on whether there is a transitional type of trait in the taxa, or whether there is no clear distinction between the various traits in that trait.

Sometimes it is abandoned or used to distinguish between a few species, for example, for several closely related species, the various leaf shape differences are not very large, and it is not very useful to describe and summarize separately, that is, to consider both intraspecific and interspecific variation.

3) In the process of compilation, whether it is to first summarize the traits that can be divided into two categories, and then select the traits to continuously decompose, or to first capture the traits that can be divided into two categories, group the described objects, and then "dismember" step by step, it is necessary to pay attention to finding the traits that are relatively easy to use in the group after the group, the traits that are easy to distinguish or dichotomous, or the special traits of some species compared with other species.

Of course, this is only a strategy for artificially compiled search tables, and there are also outliers in the search tables, that is, systematic search tables with only one answer require a true and complete display of the evolutionary and developmental history of the genus of the program.

It is written using the structural characteristics of plant stems, leaves, flowers, etc.

When using the animal and plant search form, plant and animal specimens should be carefully observed or dissected, the organs should be understood, and the key items should be carefully checked. For exact matches, continue searching down until the search ends.

When compiling the search form, it is necessary to conduct a comprehensive and detailed study of the animals and plants that need to be compiled in the search, and then compare and analyze their various morphological characteristics to find out the relative characteristics of each morphology.

Then, according to the form of the key table used, the order of primary and secondary is distinguished, and the order is arranged item by item, with numbers before the description of each text.
