| 摘 要： | 系统观察了福建防己科７属１３种植物的叶脉特征。根据脉差差异分为三种类型，即：掌状脉，复出掌状脉和顶聚脉，脉序的类型与属的划分不具相关性。由于各种间在脉的起源点，一级脉的数目，分支方式，是否形成脉环，二级脉的夹角，走向及脉环的行为上，存在着种间差异，且形状稳定，这表明，防己科植物的脉序具有分类学价值，同时可为该科的系统学研究提供有用资料。

| Abstract: | Conducts the systematic observation on leaf venational patterns of 7 general and 13 species of Menispermaceae in Fujian Based on their different characteristics, the menispermaceae leaf venations are divided into three type: actinodromous, palinactinodromous and acrodromous The division of venational patterns don't relate to genera These species venational characteristics distinct from each other in a number of primary vein, ramified, the secondary veins' angle of divergence and behaviour And these distinctive characteristics are steady, which indicate that the leaf venational of menispermaceae have significance for the delimitation of species These paper also provide additional evidence for evolution of menispermaceae |
