The earliest known collections of Bolboschoenus glaucus in North America, one a rice-field weed in Colusa County, California, and the other from Long Island, New York, are both dated 1923. The reports (as Scirpus tuberosus Desfontaines) from Quebec and Alabama are based on misidentifications.
Bolboschoenus glaucus was confused with B. maritimus worldwide until recently (J. Browning et al. 1995, 1997; S. G. Smith 1995). The name Scirpus tuberosus Desfontaines (= S. maritimus Linnaeus var. tuberosus (Desfontaines) Roemer & Schultes) was misapplied to B. glaucus by A. H. Beetle (1942) and T. Koyama (1962b). Putative B. glaucus × B. maritimus hybrids are locally common at Lake Lowell near Nampa, Canyon County, Idaho, and in California, where B. glaucus and putative hybrids are common weeds of rice fields and are cultivated with B. maritimus as food for waterfowl (J. Browning et al. 1995). Some specimens of B. maritimus from Long Island, New York, where B. glaucus has also been collected, suggest introgression from B. glaucus.
