The only known noncoastal localities of Bolboschoenus robustus are in Arkansas, Louisiana, and southeastern Texas. On the Gulf Coast B. robustus sometimes has a triangular, membranous, veinless area in the mouth of the leaf sheath, which is typical of B. maritimus.
The name Bolboschoenus robustus has been erroneously used for both B. maritimus and B. robustus in most literature on the flora of the Pacific coastal states. Putative hybrids of B. robustus with B. maritimus are common in zones of sympatry; they often have long-lanceolate spikelets. The type of Scirpus maritimus forma agonus Fernald is probably a B. maritimus × B. robustus hybrid. Bolboschoenus novae-angliae is probably derived from B. fluviatilis × B. robustus (J. Browning et al. 1995). Putative B. maritimus × B. robustus hybrids are known from New Brunswick and Nova Scotia, north of the known range of B. robustus (J. Browning et al. 1995).
