|discussion=<p>Elodium elodioides was first recognized within the genus as a variety by Best, and was maintained as such by Crum, Steere, and Anderson and by Grout within the variation of the other two North American species of Elodium (as Helodium) until reinstated as a species by Eckel. As the original authors stated, the species shares characteristics of the other two, but otherwise does not intergrade with them. The stem central strand is not present in plants of E. blandowii nor do seta and capsule dimensions of that species match those of E. elodioides. The short laminal cells with strongly displayed papillae and cordate-acuminate leaf shape do not intergrade with the translucent, nearly smooth-celled, lanceolate leaves of E. paludosum.</p>
