目的:为山东产木贼科草药经典分类提供属种间形态解剖学依据。方法:采用光镜和扫描电镜对山东产2属5种1变种木贼科草药进行了形态解剖学的研究。结果:木贼属和问荆属在气孔类型、气孔保卫细胞表面附属物及内皮层层数等方面有显著差异;山东木贼科植物维管束内均有侧生木质部。结论:依据茎的内部结构和表面特征可将它们进行属间分类,但属内种间差异较小

The morphology and anatomy of two genera, five species and one variety of Equisetaceae produced in Shandong Province were studied under light and scanning electron microscope There are remarkble differences between Equisetum L. and Hippochatete Milde in the type of stomas, attachments on the surface of stoma guard cells and the number of epithelial layers; and the presence of lateral xylem in all vasular bundle of Equisetaceae from Shandong. The results showed that they can be identified taxonomically according to their inner structual and epidermal characteristics of stem between different genera, but with little difference among species of same genus
