30-100 cm, erect to geniculate, with narrow, sunken glandular bands. |
Sheaths | glabrous, occasionally glandular, apices hairy, hairs to 5 mm; ligules 0.4-0.8 mm, ciliate; blades (1)5-20 cm long, (1)3-5(10) mm wide, flat to involute, abaxial surfaces glabrous, sometimes glandular, adaxial surfaces scabridulous, occasionally also hairy. |
sometimes glandular, apices hairy, hairs to 5 mm; ligules 0.4-1 mm; blades 5-21 cm long, 2-6(7) mm wide, flat to involute, with small crateriform glands on the keels and veins, sparsely pilose adaxially. |
Panicles | (3)5-16(20) cm long, 2-8.5 cm wide, oblong to ovate, condensed to open; primary branches 0.4-5 cm, appressed or diverging 20-80° from the rachises; pulvini glabrous or hairy; pedicels 0.2-3 mm, stout, straight, stiff, usually divergent, occasionally appressed. |
4-19 cm long, 0.8-7 cm wide, oblong to ovate, glomerate, spikelets clustered in 1-sided groups; primary branches 0.5-7.5 cm, diverging 10-90° from the rachises, angled, sinuous, glandular; pulvini hairy, hairs to 2 mm; pedicels 0.2-2 mm, stout, erect, without a narrow band or abscission line near the apices. |
Spikelets | 6-20 mm long, 2-4 mm wide, ovate-lanceolate, plumbeous, greenish, with 10-40 florets; disarticulation below the florets, each floret falling as a unit, rachillas persistent. |

Discussion | Eragrostis cilianensis is an introduced European species that now grows in disturbed sites such as pastures and roadsides, at 0-2300 m, through most of the contiguous United States and southern Canada. The English name refers to the odor of fresh plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eragrostis echinochloidea is native to southern Africa. It is now established in Arizona, growing in gravel soils, often along roadsides and in sidewalks, from 700-1000 m. It has also been found in Prince George's County, Maryland. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
