Characteristic species of high quality chert/sandstone woodlands in the southern third of Missouri. It puts the villous in villosissimum! It is well adorned with long, wiry hairs that are exceedingly longer than the sheaths are wide. It is often prostrate and messy in posture later in the growing season. Most similar to D. praecocious but their habitats almost never overlap.
Spikelets 2.1-2.5 mm, usually ellipsoid, with dense, spreading, papillose-based hairs.
