Botanical Name
Aristida dichotoma Michx. var. curtissii Gray
Common Name
Curtiss' Three-awn Grass
Aristida curtisii (A. Gray ex Wats. & Coult.) Nash; Aristida basiramea Engelm. ex Vasey var. curtissii (A. Gray ex S. Wats. & Coulter) Shinners
Flora of Virginia Name/Status
Aristida curtissii (A. Gray ex S. Watson & Coulter) Nash
Treated as a species by Flora of the Southeastern U.S. and Flora of Virginia "for simplicity." However, this seems somewhat arbitrary since the taxon has been treated as a var. of both A. dichotoma and of the western A. basiramea. Pending modern molecular studies, we follow FNA and others in treating this taxon as a var. of A. dichotoma.
Dry clearings, fields, roadsides, and thin soils on outcrops; usually in shallow, barren, or compacted soil. Infrequent in the Coastal Plain and Piedmont; rare in the mountains.
