    [GB]
    Habit
    Perennial; caespitose. Butt sheaths thickened and forming a bulb; pubescent. Culms 25-100 cm long. Ligule a fringe of hairs. Leaf-blades 6-30 cm long; 2-8 mm wide. Leaf-blade surface pubescent, or hirsute.
    Inflorescences
    Inflorescence composed of racemes. Racemes 5-16; borne along a central axis; unilateral; 1-6 cm long. Central inflorescence axis 4-11 cm long. Rhachis wingless; angular; villous on surface. Spikelet packing adaxial; regular; 2 -rowed. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; acuminate; 3.5-5 mm long; falling entire. Spikelet callus oblong (black); incorporating lowest rhachilla internode with adnate lower glume; 0.5 mm long.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; acuminate; 3.5-5 mm long; falling entire. Spikelet callus oblong (black); incorporating lowest rhachilla internode with adnate lower glume; 0.5 mm long.
    Glume
    Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; clasping; 0.33-0.5(-0.66) length of spikelet; membranous; without keels; 3-5 -veined. Lower glume surface villous. Lower glume apex acute, or acuminate. Upper glume elliptic; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume surface villous. Upper glume apex acuminate.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; elliptic; 1 length of spikelet; membranous; 5 -veined; villous; acuminate. Fertile lemma elliptic; 3 mm long; indurate; without keel. Lemma surface rugulose. Lemma margins involute. Lemma apex acute; muticous, or mucronate. Palea involute; indurate; without keels.
    Flowers
    Anthers 3; 1 mm long.

    Gramineae, W. D. Clayton. Flora Zambesiaca 10:3. 1989

    Habit
    Densely tufted perennial, the base ± bulbous and clad in silky tomentose sheaths.
    Culms
    Culms 25–100 cm. high.
    Leaf lamina
    Leaf laminae pubescent to villous.
    Inflorescences
    Inflorescence of 5–16 racemes, these 1–6 cm. long, bearing spikelets singly in 2 rows on a villous triquetrous rhachis.
    Spikelets
    Spikelets 3.5–5 mm. long, ovate-elliptic, silky villous with off-white hairs these becoming longer above and often gathered into a loose transverse fringe, acuminate to a subulate point, supported by a cylindrical black stipe c. 0.5 mm. long.
    Bracts
    Inferior glume 1/3–1/2 (2/3) length of spikelet, acute to acuminate; superior glume and inferior lemma acuminate to a subulate point up to 1 mm. long. Superior lemma obscurely rugulose, acute to mucronate.
