摘　　要：[Objective] The aim was to make pharmacognostic research of Thalictrum foeniculaceum to lay foundation for development of the plant and formulation of re- lated medicinal quality standard. [Method] Based on Thalictrum foeniculaceum plants, morphological characters of the plants, and the paraffin sections and powders of dif- ferent organs were observed with an optical microscope. [Result] Cross-section of roots of Thalictrum foeniculaceum is typical secondary structure of dicotyledon and anticlinal wall of endodermis is curve. What＇s more, vessel type is diversified, in- cluding reticulate vessel, spiral vessel, and bordered pit vessel. In addition, the leaf can be classified into basal leaf and stem leaf, of which the former is ternate vein and bifacial leaf, and the latter is isolateral leaf. The cells in palisade tissue are 2-3 lists and small granules can be found in surface of leaf epidermal cells; pollen grain is round and scattered. [Conclusion] The research laid foundation for development of plant resources and formulation of quality standard for Thalictrum foeniculaceum.[目的]系统开展丝叶唐松草的生药学研究,为其植物资源的开发利用和药材质量标准的制定奠定基础。[方法]以野生丝叶唐松草为试验材料,对其进行形态学观察,并利用光学显微镜对其各器官的石蜡切片和粉末临时装片进行观察。[结果]丝叶唐松草根横切面为典型双子叶植物次生构造不发达类型,内皮层细胞垂周壁弯曲。导管有网纹、螺纹或具缘纹孔等类型,茎中类型最多。叶分基生和茎生,基生叶为两面叶,茎生叶为等面叶,两种叶的栅栏组织细胞均为2～3列,叶表皮细胞表面有小颗粒,气孔横列式,基生叶叶脉为三出脉。花粉粒圆形,具散孔,花粉囊内壁细胞呈叉状。[结论]该研究结果为丝叶唐松草植物资源的开发利用、药材鉴别以及质量标准的制定提供了重要参考。
