    nonem

    Habit
    Annual. Culms erect; 5-32.5-60 cm long. Ligule an eciliate membrane.
    Inflorescences
    Inflorescence a panicle. Panicle glomerate. Spikelets subtended by an involucre. Fertile spikelets sessile; 3-5 in the cluster. Companion sterile spikelets sessile; 3-5 in the cluster. Involucre composed of imperfect spikelets.
    Spikelets
    Companion sterile spikelets represented by single glumes; persistent. Companion sterile spikelet glumes awned. Spikelets comprising 3-6 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 2-4.125-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Sterile
    Companion sterile spikelets represented by single glumes; persistent. Companion sterile spikelet glumes awned.
    Fertile
    Spikelets comprising 3-6 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 2-4.125-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet. Lower glume lanceolate; 1 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate; awned. Upper glume lanceolate; membranous; 1-keeled; 1 -veined. Upper glume apex acuminate; awned; 1 -awned.
    Florets
    Fertile lemma ovate; membranous; keeled; 3 -veined. Lemma midvein ciliate. Lemma margins ciliate. Lemma apex acuminate; awned; 1 -awned. Palea 2 -veined. Palea keels winged; with toothed wings. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 1, or 2. Anthers 1-3. Stigmas 2; sparsely hairy.
    Fruits
    Caryopsis with free soft pericarp.
    Distribution
    Africa, or Temperate Asia (1), or Tropical Asia (1), or Australasia (1).

    Inflorescences
    Inflorescence of dense globular spikelet-clusters (glomerules) borne at intervals along a central axis and sometimes confluent, the outer spikelets of each glomerule with enlarged inferior glume and with lowermost lemma, or all lemmas, empty and glume-like, thus forming a chaffy involucre.
    Spikelets
    Spikelets 3–6-flowered; glumes subequal, a little shorter than the spikelet; floret callus short, obtuse; lemmas keeled, 3-nerved, ciliate on the margins and keel, entire, ± awned; palea a little shorter than the body of the lemma, the keels narrowly or conspicuously winged, the wings entire or variously notched.

    Habit
    Glabrous annuals with erect culms
    Leaves
    Leaf-blades linear, flat; ligule membranous
    Inflorescences
    Inflorescence of dense globular spikelet-clusters arranged at intervals along the main axis, or these sometimes confluent to form a continuous cylinder, the glomerules (and also lesser clusters within the glomerule) ± subtended by an involucre of glumaceous bracts; bracts linear, tapering from the base to an acuminate tip
    Spikelets
    Spikelets 3–6-flowered, ovate, laterally compressed; glumes subequal, a little shorter than the lemmas, lanceolate, keeled, 1-nerved, acuminate to a short awn-point; lemmas ovate, keeled, 3-nerved, cilate on margins and keel, ± awned; palea a little shorter than the body of the lemma, the keels narrowly or broadly winged, the wings entire or variously notched; lodicules 1–2; stamens 1–3; styles 2, the stigmas very scantily plumose.
