Nees
Common names: Neverfail lovegrass
Treatment appears in FNA Volume 25. Treatment on page 78.

Plants perennial; cespitose, with innovations and thickened or knotty plant bases; plant bases with woolly hairs, hairs coarse, to 2 cm. Culms 12-60 cm, erect, glabrous or hairy near the base, often shiny below the nodes. Sheaths glabrous, summits shortly pilose, hairs to 0.5 mm; ligules 0.3-0.5 mm, ciliate; blades 3-11 cm long, 0.7-2 mm wide, involute or flat, glabrous abaxially, scabridulous adaxially. Panicles 6-11 cm long, 2-4 cm wide, narrowly ovate, loosely contracted; primary branches 1-3 cm, compact, appressed or diverging to 30° from the rachises, sometimes naked near the base; pulvini glabrous; pedicels 0.2-3 mm, diverging, scabridulous. Spikelets 3-6 (15) mm long, 1.3-2 mm wide, linear-lanceolate, stramineous, with 9-30 florets; disarticulation irregular or basipetal, paleas persistent. Glumes subequal, 1-1.3 mm, ovate, membranous, apices obtuse to acute; lemmas 1.4-1.6 mm, ovate, membranous, glabrous, lateral-veins conspicuous, green, sometimes obscure towards the apices, apices obtuse; paleas 1.4-1.6 mm, hyaline, apices truncate, ciliolate; anthers 3, 0.5-0.8 mm, yellowish. Caryopses 0.4-0.5 mm, oblong-ellipsoid, strongly dorsally compressed, usually with a shallow dorsal groove, smooth to finely striate, mostly light-brown, bases often greenish. 2n = unknown.

Discussion

Eragrostis setifolia is an Australian species that was collected around the Santee Wool Combing Mill, Jamestown, Berkeley County, South Carolina, in 1958. It is not known to have spread from that location. There is no illustration of the species because it was a late addition to the treatment.
