6种五倍子的组织解剖学表现出一致性:表皮层由1层细胞组成,无气孔结构,皮层薄壁组织在五倍子壁结构中占最主要的部分,乳汁道与维管束伴生,贯穿于倍壁,由外至内乳汁道、韧皮部、木质部依序排列,皮层薄壁组织中,导管螺纹状加厚。不同种类的五倍子,其壁厚,表皮毛密度和形态、表皮层形状、维管束的分布存在明显的差异,附6种五倍子组织学特征检索表。

[Abstract]
Histological anatomy study on six varieties of Chinese gallnut showed a similar feature:epidermal cells consisted of only a single layer,with no stomata) apparatus ;parenchyma formed the main element of gallnut wall;laticifer followed vessel tissues to penetrate through the gallnut wall reaching the phloem and xylem in an orderly fashion. In the epidermal parenchyma) tissue,vessel element thickened spirally. Different varieties of gallnuts differed in their wall thickness ,shape and denseness of epidermal hair. A list of histological charac-teristics were tabulated for reference.
