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.
