| 摘 要： | 利用光学显微镜和扫描电镜对海三棱藨草（×Bolboschoenoplectus mariqueter（Tang&F.T.Wang））及其5个近缘种的果实形状、果皮微形态特征进行观察和分析。结果显示，海三棱藨草果实形状为双凸状，表面为波形网状纹饰，外果皮为中果皮厚度的2倍，与扁秆荆三棱（Bolboschoenus planiculmis（F.Schmidt） T.V.Egorova）明显不同，而与海滨三棱草（Bolboschoenus maritimus（L.） Palla）相似。研究结果支持将海三棱藨草归入三棱草属，不支持将海三棱藨草作为扁秆荆三棱的异名，推测其可能为海滨三棱草水滨亚种（Bolboschoenus maritimus subsp.paludosus（A.Nelson） T.Koyama）的异名。

| Abstract: | Nutlet shape, pericarp micromorphology, and anatomical characters of×Bolboschoenoplectus mariqueter (Tang & F. T. Wang) and related species were observed and studied under light and scanning electron microscope. The nutlets of×Bolboschoenoplectus mariqueter were biconvex, with waveform reticulate sculpture and exocarp twice as thick as mesocarp. The species differs markedly from Bolboschoenus planiculmis (F. Schmidt) T. V. Egorova by these characters but is similar to Bolboschoenus maritimus (L.) Palla. Results showed that×Bolboschoenoplectus mariqueter should be assigned to Bolboschoenus . Furthermore, it is not synonymous with Bolboschoenus planiculmis , but could be a synonym of Bolboschoenus maritimus subsp. paludosus (A. Nelson) T. Koyama. |
