The leaves of some trees can keep dripping small drops of water. Standing under the tree feels like rain in Mao Mao! what kind of tree is it?

In some tropical areas such as South America, there is a so-called "rain tree", which is about 20 meters high and has a flat-topped umbrella crown with a maximum expansion area of 30 meters. The reason why this tree rains lies in its peculiar leaves. The leaves of the "Rain Tree" about 40 cm long are bowl-shaped, and the liquid falling on the leaves will gather together. At night, the leaves will be rolled up and wrapped in the accumulated liquid. When the temperature is high during the day, the leaves will slowly disperse, and the accumulated liquid will overflow the leaves, forming the so-called "rain" phenomenon.

Coincidentally, in Tianmingshan Hot Spring Scenic Spot in Ninghai, Zhejiang, there are also two strange trees that will rain. These two trees, one of which is a sandalwood tree, grow halfway up the mountain and have higher terrain. According to people who work nearby, it has been raining intermittently since the beginning of spring. Everyone thinks it's strange. In addition to this sandalwood tree, a holly tree downstream of the reservoir also has this ability. According to an insider, sometimes it will rain all day, and the rainfall is large and small.

Associate Professor Ni Sui, a botanist at the School of Life Science and Bioengineering of Ningbo University, believes that this is mostly related to the living environment of trees and their own special structures. Professor Ni said that from the botanical point of view, every plant has a kind of transpiration tension, which can help plants absorb water from the ground and transport it to all corners of the body in sunny conditions. The phenomenon of plant dripping mostly occurs in the growth environment with sufficient water. When the light is strong in summer, transpiration will be strengthened, and the water absorption capacity of plants will become particularly strong at night, and sometimes it may absorb too much water, which will be discharged from the drainage holes at the edge of leaves during the day. At the same time, plants with weak water storage capacity and weak transpiration will also be unable to transpiration because of excessive water absorption, forming a dripping phenomenon.
