摘　　要：利用光学显微镜和扫描电镜对山东产藨草属Scirpus L.(广义)11个类群的坚果果皮微形态进行了观察和研究,该属11种的微形态可以分为4个类型,即:Ⅰ波形网状纹饰,Ⅱ网瘤状复合纹饰,Ⅲ平滑型纹饰,Ⅳ横长网状纹饰。研究结果支持将藨草属Scirpus L.(广义)中藨草亚属Subgen.Scirpus的具球茎藨草组Sect.Bolbos-choenus Ascheron、藨草组Sect.Scirpus和丝状刚毛藨草组Sect.Trichophorum(Pers.)Darl.分别提升为三棱草属Bolboschoenus(Ascheron)Palla和藨草属Scirpus L.以及将藨草属Scirpus L.(广义)中秆苞藨草亚属Subgen.Isolepis的湖边藨草组Sect.Schoenoplectus Reichb.和藨草组Sect.Actaeogeton Reichb.提升为水葱属Schoenoplectus(Rchb.)Palla的处理意见。认为应在水葱属下设立湖边水葱组Sect.Schoenoplectus(Reichb.)F.Z.Li&L.N.Liu,藨草组Sect.Actaeogeton(Reichb.)F.Z.Li&L.N.Liu,剑苞藨草组Sect.Ehren-bergii F.Z.Li&L.N.Liu。支持将青岛藨草Scirpus trisetosus Tang et Wang作为藨草Scirpus triqueter L.异名处理的意见。并对山东藨草属种类的学名进行了订证。The micro-morphological characteristics of nut epidermis of 11 species of Scirpus from Shandong were studied under light microscope and scanning electron microscope （SEM）. The micro-morphological characteristics of the nut epidermis were divided into four types： IWaveform reticulate sculpture, Ⅱ Tuberculate-reticulate sculpture, HI Smooth sculpture,and IV reticulate sculpture. The evidence supported that section Sect. Bolboschoenus Ascheron,Sect. Scirpus ＆ Sect. Trichophorum （Pers.） Darl., which belongs to Subgen. Scirpus should be promoted to Bolboschoenus （Ascheron） Palla, Scirpus L.. Sect. Schoenoplectus Reichb. ＆ Sect. Actaeogeton Reichb,which belongs to Subgen. Isolepis should be promoted to Schoenoplectus （ Rchb. ） Palla. Sect. Schoenoplectus （ Reichb. ） F. Z. Li ＆ L. N. Liu, Sect. Actaeogeton （Reichb.） F. Z. Li ＆ L. N. Liu,Sect. Ehrenbergfi F. Z. Li ＆ L. N. Liu should be retained in Schoenoplectus （Rchb.） Palla. Evidence of the micromorphological characteristics of the fruits supported that Scirpus trisetosus Tang et Wang should be treated as a synonym of Scir- pus triqueter L. Eight species of plants names of Scirpus from Shandong have been amended.
