It is possible that the plants here placed in Bolboschoenus maritimus subsp. maritimus were introduced from Europe or were produced in North America by introgression from B. robustus or B. novae-angliae. Some specimens from the northern Atlantic coast are intermediate between B. maritimus subsp. maritimus and subsp. paludosus in having many bifid styles and only a few trigonous achenes. Collections from an abandoned oil-well site in southern Ontario (Lambton County) probably represent introductions from Europe. They have very slender leaves and culms, trifid styles, and narrowly cylindric spikelets. Although these specimens resemble some plants of B. maritimus in the broad sense from southern Europe, as well as B. glaucus × B. maritimus hybrids, they cannot be definitely identified because they lack achenes.
