S. Watson
Common names: Elliott's lovegrass
Treatment appears in FNA Volume 25. Treatment on page 99.

Plants perennial; cespitose, with innovations, without rhizomes, not glandular. Culms 25-80 cm, erect, glabrous and shiny below the basal nodes. Sheaths sparsely hairy at the apices, hairs to 6 mm; ligules 0.2-0.4 mm; blades 6-30 (52) cm long, 2-4.5 mm wide, flat, abaxial surfaces glabrous, adaxial surfaces scabridulous, some¬times with a few scattered hairs near the base. Panicles (25) 30-60 cm long, 15—45 cm wide, broadly ovate to obovate, open, diffuse; primary branches mostly 5-25 (32) cm, diverging 20-90° from the rachises, capillary; pulvini hairy; pedicels (4) 10-35 (50) mm, widely diverging, capillary, all the pedicels on each branch longer than the spikelets. Spikelets 4-18 mm long, 1.4-3 mm wide, linear-lanceolate, grayish-green or stramineous to purplish, with (6) 9-30 florets; disarticulation acropetal, below the lemmas, paleas persistent. Glumes narrowly lanceolate, membranous; lower glumes 1.1-3.4 mm; upper glumes 1.6-3.4 mm, apices acuminate; lemmas 1.8-4.4 mm, lanceolate, membranous, lateral-veins evident to inconspicuous, sometimes greenish, apices acute to acuminate; paleas 1.1-3.5 mm, hyaline to membranous, narrower than the lemmas, apices obtuse; anthers 2, 0.3-0.8 mm, purplish or brownish. Caryopses 0.6-0.8 mm, ovoid to ellipsoid, finely striate, reddish-brown. 2n = unknown.
