副卫细胞

副卫细胞数目0～12个；

The numbers of subsidiary cells from zero to twelve .

副卫细胞的数目、列方式、特征可作为分类学的依据。

The number , arrangement and character of subsidiary cells is often of value in taxonomy .

对叶片的形态特征包括叶片下表皮气孔类型、保卫细胞和副卫细胞的特征、叶片两面的普通细胞（形状和垂周壁特征）和表皮毛进行了较详细的描述。

And ordinary cells ( in shape and anticlinal walls feature ) as well as the trichomes in both sides of the leaves are described in detail .

气孔器为单唇单环式，围绕每个气孔的副卫细胞数目多为5～6个；副卫细胞的平周壁明显加厚，具乳突状突起，拱盖着下陷的保卫细胞；

The stomatal apparatus is haplocheilic and monocytic : the sunk guard cells are usually surrounded by 5 ~ 6 subsidiary cells with thicken and papillate periclinal walls .

副卫细胞：是特化了的植物表皮细胞的一种，紧邻保卫细胞，在植物气孔的开闭过程中起一定作用。

Subsidiary cell ( accessory cell ) One of a number of specialized epidermal cells of a plant that are found adjacent to the guard cells , and may help in opening and closing the stomata .
