Compound

leaves that give birth to several small leaves on a common leaf handle or leaf shaft. Each leaf has a significantly separated base, and sometimes has its own small leaf handle. The compound leaf is composed of most small leaves, such as compared with the same size of a single leaf, although the total area of the blade is reduced, but the wind, rain, water added to the blade pressure or resistance is much less, which is an adaptation to the environment. According to the arrangement and number of small leaves on the leaf shaft, can be divided into palm-shaped compound leaves, three re-leaf, feather-like compound leaves. Several small leaves are formed at the end of a common leaf handle and arranged into palm-shaped, called palm-shaped compound leaves, such as seven-leaf trees. 3
small leaf set at the end of the common leaf handle, called three out of the compound leaves, such as radon. The leaves are arranged on both sides of the leaf shaft formed by the extension of the leaf handle and are feathered, called feathery compound leaves. The total number of small leaves is a double number, called an even feather-like compound leaf, such as peanuts, the total number of small leaves is singular, called an odd feather-like compound leaf, such as rose, the leaf shaft is no longer branched for a feather-like compound leaf, such as the moon Season; branching only
1
for the second feather-like re-leaf, such as Hehuan, branching
2
times for three-back feather-like re-leaf, such as Nantianzhu.
