Although Linnaeus's plant taxonomy had a profound impact on the horticultural world, the way it started with "flowers" was actually not the same as the way most people distinguish plants. For ordinary people, when they see a plant, the first and easiest way to distinguish plants should be the difference between "grass" and "wood". The proverb says, "A man is not a plant, and he is ruthless", which reflects this very intuitive classification.
However, if you use the latest biological theory to examine this sentence, there are actually some problems: because many plants actually Special Database have their own "feeling" and "communication" methods, just because plants and animals have evolved separately for too long. , so that most people are not able to understand the emotional world of plants. On the other hand, although most people think that it is not difficult to separate plants from "grass" and "wood", for botanists, there are actually many disputes that can be discussed about the difference between grass and wood. . For example, do you think banana trees should be classified as "herbaceous" or "woody" plants?
However, to explain the origin of this controversy, we still need to understand what the so-called "herbs" and "woody" in botany refer to? In fact, in terms of plant taxonomy, "grass" and "wood" are actually a kind of "stem". The so-called "woody plants" refer to plants with developed cambium in the stem and relatively high lignification. "Herbal plants" refer to plants with underdeveloped cambium in the stem and relatively low lignification.
