Taxonomic Comments
This record is for a broad treatment of Sparganium emersum as recognized by Kaul in FNA (2000, vol. 22) and by Haines (2011), including S. emersum var. acaule (which FNA does not distinguish from typical S. emersum). Ito et al. (2016) recognize S. acaule as a distinct species and a more narrow concept of S. emersum which is equivalent to S. emersum var. emersum recognized by Haines (2011). Kartesz (1994, 1999) recognized a broad concept of S. angustifolium that included both S. acaule and S. emersum.
