Discussion
Calamovilfa brevipilis grows in moist to dry pine barrens, savannahs, bogs, swamp edges, and pocosins. It is a common grass on the New Jersey pine barrens and locally common across the coastal plain of North Carolina, but rare at present in Virginia and South Carolina. The length of the ligule hairs tends to increase from 0.3 mm or less in the north to 0.5 mm at the southern end of its range.
