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.
