Habit | Plants annual; tufted, without innovations, without glands. | Plants perennial; cespitose, with innovations, without rhizomes, not glandular. | ||||
Culms | (3)9-75 cm, erect or geniculate in the lower portion, not rooting at the lower nodes, glabrous. |
25-95(110) cm, erect, glabrous. |
||||
Sheaths | hairy on the margins and at the apices, hairs to 4 mm; ligules 0.2-0.5 mm; blades 1.8-12(15) cm long, 2-5 mm wide, usually flat, occasionally involute, glabrous or ciliate basally. |
glabrous, summits hairy, hairs 1-3 mm; ligules 0.2-0.4 mm; blades (8)12-40 cm long, 2-5 mm wide, flat to involute, abaxial surfaces glabrous, adaxial surfaces scabridulous and glabrous or long ciliate basally. |
||||
Panicles | 1.7-15 cm long, 0.2-5 cm wide, cylindrical, contracted or open, branches usually forming glomerate lobes, sometimes more open, often interrupted in the lower portion; primary branches 0.4-4 cm, appressed or diverging to 50° from the rachises; pulvini usually glabrous, occasionally sparsely pilose; pedicels 0.1-1 mm, erect, shorter than the spikelets, glabrous. |
terminal, 15-30(45) cm long, (4)8-17 cm wide, narrowly ovate, open to contracted; primary branches 5-15 cm, diverging 20-90° from the rachises, often capillary, usually naked basally; pulvini glabrous; pedicels 0.3-6 mm, mostly appressed, scabridulous, always shorter than the spikelets. |
||||
Spikelets | 1.8-3.2 mm long, 1-2 mm wide, elliptical-ovate to ovate-lanceolate, yellowish-brown, sometimes with a purple tinge, with 6-11 florets; disarticulation basipetal, glumes peristent. |
6-15(18) mm long, 1.3-2(2.2) mm wide, narrowly lanceolate, plumbeous, occasionally with a reddish-purple tinge, with 8-30(40) florets; disarticulation usually in the rachilla below the florets, occasionally the lemmas falling separately, leaving the paleas on the rachilla. |
||||

Discussion | Eragrostis ciliaris is native to the paleotropics. It is naturalized in parts of the United States, growing along roadsides, on waste sites, in xerothermic vegetation, and sometimes in saline habitats, at 0-200 m. It may be more widespread than indicated. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eragrostis bahiensis grows in sandy soils near river banks, lake shores, and roadsides, at 0-200 m. Its range extends south from the Gulf Coast of the United States through Mexico to Peru, Bolivia, Paraguay, and Argentina.
