Notes: FNA23: "A. Cronquist (1969) considered Carex breweri and C. engelmannii conspecific; he distinguished them at the varietal level by a difference in pistillate scale characters. The correlated differences in perigynium shape and veins, the dimensions of most structures, and the foliar anatomy support their retention as distinct species."
