Festuca bromoides L.

Flowering stems 5–35(–50) cm long, glabrous or roughened. Leaf blades 1–15 cm long, 0.5–2.5 mm wide, often sparsely hairy on the upper surface. Inflorescences 5–15 cm long. Spikelets 5–12 mm long (excluding the awns), with 3–5(–7) relatively loosely spaced florets, the rachilla 0.9–1.1 long between the attachment points of the florets. Lower glume 3.5–5.0 mm long, 1/2–3/4 as long as the upper glume. Upper glume 4.5–7.0 mm long. Lemmas with the body 4.0–7.5 mm long, glabrous or roughened, the tip with an awn 3–12 mm long. Anthers 0.5–0.8 mm long. Fruits 3–4 mm long. 2n=14, 42. April–May.

Introduced, known from a single site in Jasper County (native of Europe, widely naturalized in North America, South America, Africa, and Australia). Roadsides near a chert glade.

In North America, this species has become a widespread weed, most commonly from British Columbia to Baja California Norte. It is encountered sporadically in the eastern and midwestern United States and is apparently absent from the Great Plains. The first report for Missouri was by Christ (1988).
