Haber in 2004 (H154).Elatine triandra rank of 5 transferred to E. americana (syn E. triandra var. americana) which is the Kartesz 1999 treatment;; Reviewed in 2010, no change. Sean Blaney’s comments: ranks refer to E. americana, E. triandra in the strict sense does not occur in Canada (northeast US only), Canadian material is referred to E. americana from which E. ojibwayensis was recently segregated (M Anoins 2010); ; Reviewed in 2015 by Marilyn Anions; no change
