Have you ever seen a palmetto?

Palmetto looks a lot like a palm, and so does itPalmaceae, but it is in the genus Palmetto, and the palm is in the genus Palm.

Many people will not be able to tell the difference between palmetto and palm silly, so how can they tell the difference?

There are three points that can be seen from the bottom up:

1. Look at the brown clothes。Brown coat is the layer of brown skin on the trunk of the tree and wrapped around the bark, it is strong and rough, suitable for making coats, ropes, pockets, palm mats, etc.

Since the palm is called the palm, its brown coat is of course thick and thick, and the trunk of the whole body is densely wrapped by it, as if it is a winter coat because of the fear of cold. As for the palmetto, its brown coat is only found in the upper part of the trunk near the leaves, and the middle and lower parts are smooth, which is like a cool summer dress, and the neck of the old man is added with a decorative scarf.

2. Look at the leaves。Their leaves are concentrated at the top of the tree, and the leaves are palmately lobed, butThe degree of leaf splittingwithLeaf tipThere is no confusion.

The palm-like leaves of the palm are deeply lobed, almost to the center of the "palm", while the palmetto leaves are only moderately lobed, usually only half-lobed. It is for this reason that palmetto leaves are very suitable for making-Big pu fan(Now it is probably only seen in the countryside), and palm leaves are not allowed.

How to make a pu fan? Cut off the large palm-shaped leaves of the palmetto, cut off the tips of the leaves that are cracked on the periphery, leaving an uncracked ball in the center, so that it is cut into a dough fan, and then sew an edge for it with cloth, so that the cattail fan is made - the petiole is just right to make a fan handle, which is natural and convenient.

As for the leaf tip, the drooping of the leaf tip of the palmetto is often more serious, while the tip of the palm leaf is generally more upright, that is, the whole "palm" is basically on a plane.

3. Look at flowers and fruits。Palmetto isMonoeciousof,Small florets yellow-green, bisexualto form large panicles. And palm isdioeciousof,The male plant has yellow male flowers, and the female plant has yellow-green female flowers, which are also composed of large panicles.

In addition, palmetto is monoecious and has a wide state, while palm can only bear fruit if it is female.

So now, can you tell the difference between palmetto and palm?

Palmetto is a perennial evergreen tree of the genus Palmetto in the family Palmaceae, up to 20 meters high, often enlarged at the base, broad-kidney-like fan-shaped leaves, and oval-shaped olive-shaped fruits.

The fan tree is a palm tree, but the palm tree is the scientific name of the fan tree, and they are actually the same plant. The leaf sheath of the palm tree is fan-shaped, so it is quickly called a fan tree. The leaves of the palm tree can be made not only into crafts such as fans and hats, but also from its roots to make medicine.

Therefore, the difference between palmetto and fan tree: palmetto is a perennial evergreen tree of the genus Palmetto of the palm family, up to 20 meters high, often swollen at the base, with broad-kidney-like leaves and oval-shaped olive-shaped fruits. The fan tree is a palm tree, but the palm tree is the scientific name of the fan tree, and they are actually the same plant.

The leaf sheath of the palm tree is fan-shaped, so it is called a fan tree. The leaves of the palm tree can not only be made into handicrafts such as fans and hats, but also can be used to make medicine from its roots.
