|discussion=<p>A possible variety, Eriocaulon decangulare var. latifolium Chapman ex Moldenke [in N. L. Britton et al., N. Amer. Fl. 19(1): 21. 1937], has yet to be thoroughly investigated. This plant typically is in the taller range and has thicker stems and scapes than in the type; it has very stiff blunt leaves to 50 cm × 13–20 mm with thicker scapes, heads 13–20 mm wide, and floral parts in the high range for the species. It occurs in wetter situations than usual for the species, and (fide R. R. Haynes, pers. comm.) flowers later. This morphology occurs in northwestern Florida and southern Alabama within boggy edges of cypress-titi-Nyssa on permanently wet substrates.</p>
