(2715.) S. polystachya, Willd.; Hook., Fl. II., 242, in part.

Canada. (Hooker, Fl.) Magdalen Islands, KS. (McKay.) We strongly suspect that these references belong to S. cynosuroides. The remark in Gray's Manual that S. cynosuroides is only a fresh-water species, is not borne out by the facts, as all my eastern specimens were gathered in brackish marshes, and certainly the awn and other distinctive characters were just as well marked as in the specimens from the Great Lakes.
