Carex muehlenbergii Willd.
Common Name: SEDGE
Coefficient of Conservatism: 7
Coefficient of Wetness: 5
Wetness Index: UPL
Physiognomy: Nt P-Sedge

Dry sandy fields, banks, and borders of forests; dunes; oak and aspen forests.

This species and C. cephalophora are common and easily distinguished by size of perigynia and anthers, as well as the usually more elongate inflorescence of C. muehlenbergii. They are less easy to distinguish from the sporadic C. mesochorea and C. leavenworthii, although the perigynium shape of the latter and the long scales of C. mesochorea are distinctive. Plants in which the perigynia are nerveless and flatter on the ventral face are var. enervis Boott, and have essentially the same range in Michigan as plants of var. muehlenbergii, although the few collections of C. muehlenbergii from the Upper Peninsula and northern third of the Lower Peninsula are all typical var. muehlenbergii.
