From Flora of Indiana (1940) by Charles C. Deam
Infrequent to frequent throughout the state. It prefers a dry soil and is found in many habitats. Usually frequent in beech and sugar maple woods, white oak woods, and white oak and black oak woods; less frequent in moist or wet woodland, bogs, and fallow fields and along railroads. I have a specimen with pubescent sheaths and leaves, which was found growing in sphagnum in a decadent tamarack bog just east of Pokagon State Park, Steuben County. This is the only pubescent specimen I have out of 79 Indiana specimens.
Panicle rather loose; second glume acute, the length 3-6 times the folded width; lower rachilla-joint 0.8-1 mm. (S. intermedia)
