摘要：

Surface and transverse section achene structures of Bolboschoenus maritimus, B. robustus, B. fluviatilis, B. novae-angliae, B. glaucus, and the putative hybrids B. maritimus x B. robustus and B. glaucus x B. maritimus from North America are described and illustrated with SEM micrographs, The same three types of pericarp structure reported by Browning and Gordon-Gray (1993) from southern Africa were found except that the ''type 2'' (B. glaucus) was not matched precisely. Intermediate achene structures and other evidence support both the hybrid origin of B. novae-angliae (= B. fluviatilis x B. robustus) and hybridization between B. glaucus and B. maritimus. The new combination Bolboschoenus novae-angliae is made.
