    Gramineae, T. Cope. Flora Zambesiaca 10:2. 1999

    Habit
    Caespitose perennial; culms up to 50 cm tall, erect or ascending, wiry; leaf laminas (1)2–6(9) cm × 1.5–2.7(3) mm, narrowly linear, rather stiff, glaucous, flat or more often involute.
    Inflorescences
    Racemes 3–8 cm long, slender, loose, flexuous.
    Spikelets
    Spikelets 4.6–6.5 mm long (excluding the awns); inferior glume 3.4–5.1 mm long, (0.8)0.9–1.2 times the length of the lowermost lemma; superior glume ± as long as the spikelet; fertile lemmas 1–2(3), 3.2–5.3 mm long, pilose on the back, with an awn up to 5 mm long (sometimes more); sterile lemmas 3–5.
    [GB]
    Habit
    Perennial; caespitose. Culms erect; 20-60 cm long. Ligule a fringe of hairs. Leaf-blades 2-5 cm long; 1-2.5 mm wide.
    Inflorescences
    Inflorescence composed of racemes. Racemes 3-8; digitate; unilateral; 2.5-8 cm long. Rhachis angular; scabrous on margins. Spikelet packing broadside to rhachis; lax. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 4.5-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes terete; eventually visible between lemmas. Floret callus evident; 0.3 mm long; pubescent; obtuse; disarticulating obliquely.
    Fertile
    Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 4.5-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes terete; eventually visible between lemmas. Floret callus evident; 0.3 mm long; pubescent; obtuse; disarticulating obliquely.
    Glume
    Glumes persistent; similar; exceeding apex of florets; similar to fertile lemma in texture; gaping. Lower glume linear; 0.75 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume linear; 4.5-6 mm long; membranous; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume apex acuminate.
    Florets
    Fertile lemma lanceolate; 3-4 mm long; membranous; keeled; 3 -veined. Lemma surface pilose. Lemma apex dentate; 2 -fid; incised 0.2 of lemma length; awned; 1 -awned. Principal lemma awn 6-8 mm long overall. Apical sterile florets 3-5 in number; barren; in a clump; rudimentary. Apical sterile lemmas awned; 1 -awned. Apical sterile lemma awns 6-8 mm long; 3-4 per spikelet in number.
