Species

Angiosperms > Poales > Poaceae > Agrostis

Characteristics

Tufted perennial 5–10 dm; lvs flat, 2–6 mm wide, elongate, the uppermost one more than 5 cm; infl mostly pale greenish, 10–25 cm, notably longer than thick, the smooth or sparsely scabrous branches forking near or below the middle, soon divaricate, the longest ones often less than 6(–12) cm; spikelets 1.8–2.8 mm; glumes subequal, scabrous on the midvein; lemma 1.3–2 mm, awnless or rarely with a very short, slender awn near the tip; palea obsolete; anthers 0.3–0.6 mm; 2n=42. Various habitats, usually in dry soil; Que. and N.S. to Minn., s. to Fla. and Tex. The foregoing description is based primarily on the widespread and highly variable var. perennans (A.oreophila; A. schweinitzii). Plants of bogs on the coastal plain from N.J. and Md. to Miss. have somewhat larger spikelets (2.7–3.5 mm) on short pedicels, aggregated in spike-like clusters toward the ends of the panicle-branches; these are var. elata (Pursh) Hitchc. (A. elata; A. altissima)
