Eragrostis trichodes
Eragrostis curtipedicellata
Eragrostis trichodes grows in sandy to gravelly prairies, open sandy woods, rocky slopes, and roadsides, at 100-2150 m, often in associations with Quercus marilandica, Q. stellata, Juniperus, and Redfieldia flexuosa. It is endemic to the contiguous United States, and is available commercially as an ornamental. Records from outside the primary range probably reflect introductions.

The range of Eragrostis curtipedicellata extends from southern Colorado, Kansas, and Missouri to northeastern Mexico. It grows near fields, along roadsides, and in the margins of woods, at 10-1525 m.
