Torreyochloa fernaldii inflorescence A. A. Reznicek inflorescence

Puccinellia fernaldii of Michigan Flora.

Wet stream borders, pond shores, bogs, alder thickets, and wet coniferous thickets. Rather local, and often transient on shorelines, depending on water levels. This is a delicate grass with a lax and usually sprawling habit, sometimes even floating in shallow water. 

More slender and smaller than T. pallida, which it resembles and of which it is often considered a variety [T. pallida var. fernaldii (Hitchc.) Dore]. Specimens may superficially be confused with Glyceria striata, from which they differ not only in the open sheaths but also in the more strongly scabrous branches of the inflorescence.
