Scirpus validus of Michigan Flora.

Wet shores and shallow water of ponds, lakes, rivers, ditches, and marshes; occasionally in bogs; on sand, marl, or peat. This is more or an early successional species than Schoenoplectus acutus, often appearing quickly on sand bars, newly made pondshores, and ditches. 

May form large stands by itself or with other marsh species, but not in such deep water as typical of Schoenoplectus acutus. See notes under Schoenoplectus acutus.
