Carex canescens L.
Common Name: SEDGE
Coefficient of Conservatism: 8
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Nt P-Sedge

Usually in sphagnum bogs and older tamarack, cedar, and fir stands; also pond and stream margins, marshy or boggy ground, alder thickets, and rarely elm-maple swamps.

The majority of our specimens are the eastern North American subsp. disjuncta (Fernald) Toivonen, with inflorescences mostly 6–12 cm long, often nodding, and the spikes well separated, with the two lower spikes separated by more than 1.5 cm. This taxon occurs throughout the state. Most common in the Upper Peninsula is the circumboreal subsp. canescens with inflorescences 3–7 cm long and the spikes closer together, even the lowest separated by less than 1.5 cm. Separation of the two subspecies often seems arbitrary in Michigan. Small specimens may be hard to tell from C. brunnescens, but the papillose perigynia are diagnostic.
