The leaf sheaths and culm axis are pilose with hairs 3-5 mm long; hairs on the leaf surfaces are similarly long; the leaf length ranges from 2.5-10 cm, the longest leaves with long-acuminate tip ……hirtellus ssp. undulatifolius.

Leaf sheaths and culm axis glabrate to pilose (usually sparsely, but dense at sheath summit) with hairs less than 1.5 mm long; hairs on the leaf surfaces similarly long; the leaf length ranges from 1.5-6 cm, the longest leaves with acute to acuminate tip (but not long-acuminate) ………………setarius
Taxonomic CommentsFNA treats setarius as a subspecies of hirtellus; but it is confined to the New World, whereas the latter is confined to the Old.
