Descriptions

Morphology General Habit
Perennial; caespitose. Butt sheaths dark brown. Basal innovations intravaginal. Culms erect; 50-100 cm long; 2-3 -noded. Culm-internodes solid. Culm-nodes glabrous. Lateral branches lacking. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs lacking, or ciliate. Ligule a fringe of hairs. Leaf-blades 20-45 cm long; 3-4 mm wide. Leaf-blade surface scabrous; rough on both sides. Leaf-blade apex attenuate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; linear; 20-35 cm long. Primary panicle branches appressed; 1-2 -nate; bearing 1-6 fertile spikelets on each lower branch. Spikelets solitary. Fertile spikelets pedicelled. Pedicels scabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear; subterete; 15-23 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 1-3 mm long; pubescent; with longer hairs above; obtuse.
Fertile
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear; subterete; 15-23 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 1-3 mm long; pubescent; with longer hairs above; obtuse.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 15-23 mm long; 1 length of upper glume; hyaline; light brown; without keels; 3 -veined. Lower glume surface asperulous. Lower glume apex setaceously attenuate. Upper glume lanceolate; 15-23 mm long; 1.2-2 length of adjacent fertile lemma; membranous; light brown; without keels; 3 -veined. Upper glume apex setaceously attenuate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma linear; subterete; 12 mm long; chartaceous; without keel; 3 -veined. Lemma surface scaberulous; rough above. Lemma margins involute; covering most of palea. Lemma apex acute; awned; 3 -awned. Principal lemma awn spreading; flat below; 20-45 mm long overall; without a column. Lateral lemma awns gyrate; 20-45 mm long; subequal to principal. Palea 2 mm long; 0.15 length of lemma.
Morphology Reproductive morphology Flowers
Lodicules 2. Anthers 3; 6 mm long. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; linear; dorsally compressed; sulcate on hilar side; 10 mm long. Embryo 0.2 length of caryopsis. Hilum linear.
Distribution
Africa: south.
