Meadows, openings in swamps.
Much paler and also larger than S. atrocinctus, though similar in having the spikelets mostly pediceled, this is a poorly understood entity known from a few scattered localities, though perhaps overlooked. This species matures early (July) and even at maturity has greenish to pale brown spikelets. Two specimens from southernmost Michigan that will key here because of their pedicellate spikelets differ in having conspicuously reddish-brown scales and being late maturing; they are apparently the southern variant of S. cyperinus formerly segregated as S. rubricosus Fern.
