Introduction
The feather recess is a recess. The leaves becomes a lifted recess arranged on the header. If there is a small leaf in the top, it is called an odd replenish, such as walnut, banyan tree, etc. If there is two small leaves at the top, there is no counted recess, such as no patient, soap pod, etc. If the header is branched, a two-return feather complex (such as a joy) or three feathers (such as bitter).
Main Features
Patchase Reunion, in the feather replenishment, if the outer end of the leaf shaft only grows small leaves, called odd feather recovery or singular feathers , Such as a banyan tree; when the top of the leaf shaft is born with two small leaves, it is called an even-numbered recess or double feather resurvere, such as unsuccessful. In the feather resurdere, if each of the leaflets on both sides of the leaf axis, it is called a feather-shaped recess, such as a branches, such as the branches of the feathers on both sides of the leaf shaft, on both sides of the branches. The small leaves arranged in the feathers are called two-time recovery, such as Huan; with such pushing, there can be three times to back. According to the above situation, it is precisely, you can refer to the leaves of the leaves as a odd feather complex, and there is no donkey, and the happiness leaves are two-end-oriented. In the feather resurderer, if its small leaves are different, the range is uneven, or the size is interposed, called the resistant restoration, such as tomatoes, dragon buds, etc.
Shape Characteristics
The shape characteristics of the feather recessor is primarily a common leaflet or leaflet on the leaf shaft. Each small leaf has a significantly separated base, and sometimes has a small leaflet. Reunion is composed of most small leaves, such as compared with the same size single leaf, although the total area of the blade is reduced, but the pressure or resistance to the blade is added to the blade, which is much pair. An adaptation of the environment. According to the difference between the leaflets and the number of methods and the number of palms, it can be divided into palm recess, three out of recess, and the feather recess. Several leaflets are planted in the end of the common petiole, called palm recess, such as a seven-leaf tree. Three lobes were collected in the end of the common petiole, called three out of the leaves, such as alfalfa. The leaflets are arranged on both sides of the leaf shaft extending the leaflet, called a feather recess. The total number of small leaves is double, called an even-numbered recess, such as peanuts; total small leaves are singular, called odd feather relics, such as roses; the leaf shaft is no longer branched as a feather-shaped replenish, As the branches; branches are only 1 time, such as Huan; branches 2 times are three-back feather resurgery, such as South Tianshu.
Plant classification
One-time replenishing blade
a feather resurderer: is evolved from the single-shot of the feathers, Ordinary lack once, an odd number or even number of small leaves, as well as:
(1) one-time plug: 即 即 复 复 复 小 小 为 数That is, the top lobes are 2 feathers (such as decision).
(2) a odd-numbered feather resurdere: The small blades of the feathered recess are odd, that is, the top leaflet is a feather complex (like a month).
(3) One-time three-shred relic: that is, a small blade sheet with a feather-shaped recess (such as a cross iron broom).
Two-back feather resurvere
Two feathers Reunion: Also from the single-shot of Feather Ye, that is, through universal lack of secondary formation, There is also a quotiated point.
(1) Two-end number of feather residents: that is, the small blade is an even number, that is, the top lobes are 2 two-time replenish (such as hills).
(2) Two odd number of feather residents: ie the small leaves are odd, that is, the top lobes are two-back feather resurdes (such as Danshen).
Three-back feather resurgee
is also evolved by a single-shot of a feathered recess, that is, through the general lack of three times (such as Tang Song).
Multi-return recovery
is also evolved from a single-blade of the feathers, that is, by general, multiple lack formation (such as fennel).
