Discussion

Glyceria canadensis var. laxa grows in swamps, bogs, and wet woods, primarily along the eastern seaboard of North America from Nova Scotia to northeastern Tennessee. It is sometimes treated as a hybrid, G. xlaxa (Scribn.) Scribn., but several specimens have dehiscent anthers and well-formed caryopses, indicating that they are not hybrids. The report of 2n = 30 is based on counts for G. xottawaensis.
