报道了两种五味子和五种五味子的成熟木材和树皮的定性和定量特征。新近报道的该科主要是简单的穿孔板（所有物种）；在最初形成的次生木质部的导管中存在纹孔膜残余物；管胞上每个面有两到三个系列的凹坑；弥漫性轴向薄壁组织（Kadsura）；多列射线最宽处超过三个细胞宽（所有物种）；轴向木质部有精油细胞；以及比较树皮解剖学的某些细节。八角科和五味子科之间木材解剖结构的差异几乎都是程度的差异。这些差异与八角属的灌木到树栖习性有关，而不是五味子科的攀爬习性。管胞上较大的凹坑、较宽和较短的导管元件以及每mm 2 横断面的导电面积较高，这些特征与五味子科的攀爬习性有关；八角属的相反性状状态与该属生长形式的自养性质有关。
Qualitative and quantitative features are reported for mature wood and bark of two species of Kadsura and five species of Schisandra. Newly reported for the family are predominance of simple perforation plates (all species); presence of pit membrane remnants in vessels of first-formed secondary xylem; two to three series of pits per facet on tracheids; diffuse axial parenchyma (Kadsura); multiseri ate rays more than three cells wide at the widest point (all species); ethereal oil cells in axial xylem; and certain details of comparative bark anatomy. Differences in wood anatomy between Illiciaceae and Schisandraceae are nearly all differences of degree. These differences relate to the shrubby to arboreal habit in Illicium as opposed to the scandent habits in Schisandraceae. Larger pits on tracheids, wider and shorter vessel elements, and a high figure for conductive area per mm 2 of transection are features related to the scandent habit of Schisandraceae; opposing character states in Illicium relate to the self-supporting nature of growth forms in that genus.
