This is a widespread northern species of boggy shores that has been known as S. chlorocarpum Rydb. (especially var. acaule (Beeby) Fern. to the south) or erroneously merged with the circumboreal S. angustifolium Michx. The few records of these taxa from Ky. (e.g. BA) are at least partly based on misidentified americanum (e.g. colls. of R. Athey at EKY) but deserve further checking. S. emersum is known from adjacent counties in s. Ill., s. Ind. and w. Va. (K, PL, W).
