Cinna arundinacea L.
Common Name: WOOD REEDGRASS
Coefficient of Conservatism: 7
Coefficient of Wetness: -3
Wetness Index: FACW
Physiognomy: Nt P-Grass

Swamps, floodplain forests, depressions in deciduous forests, thickets, very rarely on dry forested sites.

The panicle tends to be stiffer and less open than in C. latifolia, in which it is typically lax and drooping. The ligules of C. arundinacea are more deeply tinged with reddish brown than in C. latifolia, in which they are generally colorless or nearly so.

Though known uncommonly from the western Upper Peninsula, a Farwell collection from Keweenaw Co. (749, 12 July 1890) is sufficiently out of range as to suggest a mixture of labels. It is not mapped.
