Eriocaulon aquaticum M. R. Penskar

E. septangulare of Michigan Flora.

On wet sandy or boggy shores or in shallow water, the white heads usually emersed (on scapes to 50 cm long, rarely even to 110 cm, in water, only a few cm long on land); especially characteristic of soft-water and acid lakes, where the rosettes of distinctive leaves and cross-hatched roots may form a dense turf even in deep water (1 m or more). The most common and widespread rosette-former of such lakes, although locally outnumbered by Isoëtes spp., Littorella uniflora, Juncus pelocarpus f. submersus, Lobelia dortmanna, or other associates.
