Discussion

Dichanthelium ovale subsp. praecocius is most common in the midwest and in the tallgrass prairie states. It intergrades with subsp. villosissimum, especially in the western parts of the latter's range, and to a lesser extent, with D. acuminatum subsp. fasciculatum in the northern part of its range.
