How to pretend to be a botanist? First of all, you need to know some simple geometry.

Meet unknown plants.

Turn over the map, APP, seek identification

It's better to stomp to death

It's nice to step on it, but it's embarrassing to be found out.

Is there any skill that can be learned, used, and suitable for acting tough

Of course there is!

Name or no name,

you can pretend to inadvertently

Describe the characteristics of plant leaves in technical terms

If you know the name, such as copper grass

You can say, look.

The leaves of the copper leaf are shield leaves.

If you don't know the name, like...

It doesn't matter. You can say it.

This is a bi-to tri-pinnate odd leaf.

That sounds awesome, doesn't it?

Five steps to learn this skill!

the first step

Let's see if it's simple or compound.

this is very understandable

Find a petiole growing out of a stem node.

A single leaf is a leaf attached to only one leaf.

Multiple leaflets are compound leaves.

look

Three leaves on one petiole.

Clover is compound, of course.

the second step

You need to know some simple geometric shapes

ovate

obovate

heart-shaped

lanceolate

……

Some leaves are hard to describe?

Just use a combination of words

For example, weeping willows have very narrow leaves.

We call it linear lanceolate.

The ovate leaves of lilac are wider

Then call it a broad oval.

the third step

Note leaf apex, leaf margin and base

The leaf shape seems to be changing

In fact, it is all these three parts that are changing.

Like this elm leaf.

It's not enough to say ovate leaf, you can also say it

apex acuminate, leaf margin serrate

Asymmetric radian at base

All right, now, you've been able

Professional introduction of single leaf

Too easy?

Increase the difficulty, challenge the compound leaf

the fourth step

Meet compound leaves, observe leaf axis

leaf rachis, part of the petiole bearing leaflets

Like the buckeye.

Leaflets inserted at apex of total petiole

That is to say, there is only one point on the leaf axis

palmate compound leaf

If leaflets are arranged on both sides of the common petiole

In other words, the axis is longer.

The one with the pinnate compound leaf

Look at that. Like feathers, right?

Subdivided, it is bi-pinnate

odd or even, depending on the presence or absence of leaflets at the top of the leaf axis

several times, depending on how many layers the branches of the leaf rachis have

Also, there are only three leaflets

called trifoliate compound leaf.

palmate trifoliate

And cowpeas like this

three ovate rhombic leaflets

occupy more than one point on the leaf axis.

It's pinnately ternate.

the fifth step

Read more, remember more, practice more

Did you not digest today's lecture?

don't worry

Just watch, remember, practice.

Soon, you'll be able to master

This was a super practical skill!

Where does the exercise begin? you need

Turn a page and practice. Stop.

Zoom in on the leaves.

Write down your judgment.

new

Chinese name, better use!

When you're not skilled, you can still

Verification of scientific name and Chinese name

It's both a guide and a notebook.

New knowledge can be memorized

Isn't that super convenient?

The classic store."

A natural series.

Selected paper + 180° spread binding design

It makes you want to write so much, and it's convenient to take pictures.
