摘　　要：民间药星宿菜疗效确切,使用广泛,为发掘这一民间药资源,该文建立了该药形态组织学方面的标准。笔者通过观察植物形态和药材性状、利用常规生药制片技术制片并鉴别组织构造特征等方法对其进行品种鉴别。形态观察发现植物叶的着生方式及雄蕊与雌蕊的特点可以作为《中国植物志》的完善补充。药材外观性状为全草类药材特点,主要包含根茎、茎及叶。首次报道的显微组织研究表明,根茎、茎、叶横切面、叶表面观及药材粉末特征明显且具有鉴定意义。根茎、茎横切面组织构造不发达,均有内皮层,分布许多分泌结构,根茎中存在有多种形状石细胞的厚壁组织。叶为异面叶,主脉部位韧皮部下方有纤维束,维管束和纤维束外侧有一列由薄壁细胞环绕形成的鞘。叶表面观中的气孔、腺毛、角质线纹等形态特征在上下表皮中存在差异。药材粉末特征中有腺毛、石细胞、导管等结构。综合分析认为,上述结果为星宿菜的形态组织特征,可以很好地鉴别该药。该形态组织学特征可以为星宿菜的种质鉴别和进一步开发应用奠定基础。To set standards for histomorphological studies on Lysimachia fortunei, an efficacious and widely applied folk medicine in this study, in order to develop its resources. Its species were identified by observing plant morphology and herbs appearance characters, preparing slices with routine methods and defining structural characters. According to the results of morphologic observation, leaves, stamen and pistil of this plant were different from the descriptions in Flora of China. The whole herb can be used in medicines, mainly including rhizomes, stems and leaves. According to the findings in the first study on microscopic structures, its rhizomes, stems and leaves were characteristic and worth identifying. The transaction tissue structures of rhizomes and stems were under developed and contained endodermis, secretory structures; Stems had sclerenchymata of different shapes of sclereids; Leaves were bifacial and had vascular bundles under midribs, which were surrounded by parenchymal sheathes. On the surface of leaves, stomata, glandular hairs and keratin lines were morphologically different in upper and lower epidermis. The herbal power had glandular hairs, sclereids and vessels. In conclusion, herbs of L. fortunei can be identified by the above histomorphological characteristics, which lays a foundation for further development and application of L. fortunei.keywords：folk medicine
