Pinyin shù yè
English translation: Tree leaf
Leaf veins
The veins of varying thicknesses on the leaves are called leaf veins. There are two types of leaf veins:
Reticular veins - the leaf veins are interlaced with each other to form a network. The chrysanthemums of most dicotyledonous plants have reticulate veins.
Parallel veins - veins of leaves do not intersect with each other and are generally distributed parallel. The chrysanthemums of most monocots have parallel veins.
Types
According to the number of leaves on the petiole, leaves can be divided into two types:
Single leaf—&mdash ;There is only one leaf on each petiole.
Compound leaves--each petiole has many leaflets.
