- Comments
- Often treated as a variety of Dichanthelium oligosanthes. In our area at least, this taxon seems quite different from oligosanthes, and we follow Flora of the Southeastern U.S. (Weakley et al.) in treating the two at species rank. Morphological differences are somewhat subtle, but D. oligosanthes is a species of acid, sandy soils of the Coastal Plain while D. scribnerianum is a species of base-rich soils in the mountains and northern Piedmont.
- Habitat
- Rocky woodlands, barrens, clearings, meadows, and road banks; usually on mafic or calcareous substrates. Infrequent in the mountains; rare in the n. and inner Piedmont.
