    Gramineae, E. Launert. Flora Zambesiaca 10:1. 1971

    Habit
    Perennial, 70-150 cm. high, laxly or densely caespitose.
    Culms
    Culms erect, robust, usually simple or sparingly branched from the upper nodes, glabrous, smooth, 4-6-noded; nodes glabrous, smooth.
    Leaf sheaths
    Leaf-sheaths usually lax, usually glabrous, smooth, sometimes the lower ones with long scattered hairs.
    Ligules
    Ligule an obsolete, minutely ciliolate rim; auricles usually short-ciliolate; collar glabrous.
    Leaf lamina
    Leaf-laminae up to 30 x 0.4 cm., but often much shorter, flat or involute, usually glaucous, minutely scabrous above, glabrous beneath.
    Inflorescences
    Panicle 20-25 cm. long, shortly exserted, usually erect and stiff, narrow, dense, spiciform, many-flowered; axis terete, usually glabrous, smooth; branches more or less terete, appressed, glabrous, smooth, or slightly scaberulous.
    Spikelets
    Spikelets pallid or greenish.
    Glume
    Glumes unequal, chartaceous, 1-nerved, glabrous, smooth, slightly scaberulous on the keels; the inferior up to 13 mm. long, lanceolate, acuminate, shortly awned; the superior up to 22 mm. long, narrower, gradually tapering into an awn up to 5 mm. long or with a very short awn from the sinus between 2 hyaline lacerate lobes.
    Lemma
    Lemma 8-9 mm. long, linear or tubular, pallid or dark-mottled, finely punctulate; callus 2-3 mm. long, acuminate, densely barbate; column 20-40 mm. long, strongly twisted, scabrous; awns 25-60 mm. long, subequal, very fine, scabrous; articulation between the apex of the lemma and the base of the column.
    Note
    This very polymorphic species is so extremely variable that it is rather difficult to distinguish well-marked subspecies. Although its extreme variants are so distinct that several have previously been described as species, yet in many cases they are connected by intergrading forms. When more of these forms can be examined cytogenetically, observed under uniform conditions of cultivation and used in hybridization experiments, a more satisfactory classification will be possible. For the present it is proposed to recognize groups as subspecies on the basis of a general tendency in each group to exhibit a certain combination of characters, accompanied by peculiarities in their distribution.

    Habit
    Perennial; caespitose. Culms erect; 30-150 cm long; 4-6 -noded. Culm-internodes distally glabrous. Ligule a fringe of hairs. Leaf-blades flat, or involute; 5-30 cm long; 2-4 mm wide; glaucous. Leaf-blade surface scaberulous; rough adaxially.
    Inflorescences
    Inflorescence a panicle. Panicle contracted, or spiciform; linear; continuous, or interrupted; 10-25 cm long. Primary panicle branches appressed, or ascending. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 18-22 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 2-3 mm long; bearded; pungent.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 18-22 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 2-3 mm long; bearded; pungent.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 10-13 mm long; 0.6 length of upper glume; chartaceous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex setaceously attenuate. Upper glume lanceolate; 18-22 mm long; 2.2-2.5 length of adjacent fertile lemma; chartaceous; 1-keeled; 1 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins absent. Upper glume apex entire, or dentate; 2 -fid; attenuate; awned; 1 -awned. Upper glume awn 1-5 mm long.
    Florets
    Fertile lemma elliptic; subterete; 8-9 mm long; coriaceous; without keel; 3 -veined. Lemma surface punctate. Lemma margins convolute; covering most of palea. Lemma apex acute; awned; 3 -awned. Principal lemma awn 3-branched; with 25-60 mm long limb; with twisted column; deciduous; abscissing from top of lemma. Column of lemma awn 20-40 mm long. Lateral lemma awns 25-60 mm long; subequal to principal. Palea 0.2 length of lemma; without keels.
