Discussion

Carex caryophyllea is widely distributed in Eurasia and was first recorded in North America in 1826. Carex caryophyllea may escape notice because it somewhat resembles C. pensylvanica in size, habit, scale color, perigynia pubescence, and flowering time. Carex caryophyllea is distinguished by awned scales, perigynia with thick conical beaks, mitrate achenes, and enlarged persistent style bases.
