Melinis scabrida

HABIT Perennial; caespitose. Culms decumbent; 40–100 cm long; 1–1.2 mm diam. Culm-nodes bearded. Leaf-sheaths pilose. Ligule a fringe of hairs; 0.8–1.2 mm long. Leaf-blades 2–15 cm long; 2–6.5 mm wide. Leaf-blade surface glabrous, or pubescent.

INFLORESCENCE Inflorescence a panicle.

Panicle open; oblong; 7–20 cm long; 2–4 cm wide. Panicle branches capillary; pubescent in axils.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; bearing a few hairs; hairy above.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; gibbous; 2.4–2.8(–3.2) mm long; with hairs extending 0.5–1.5 mm beyond apex; falling entire. Rhachilla internodes brief up to lowest fertile floret.

GLUMES Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume oblong; 0.2–0.8 mm long; 0.1–0.25 length of spikelet; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume surface glabrous, or pilose. Lower glume apex emarginate, or truncate. Upper glume oblong; gibbous; 1 length of spikelet; chartaceous; much thinner above; without keels; 5(–7) -veined. Upper glume surface glabrous, or pubescent; hairy below. Upper glume margins scaberulous; eciliate, or ciliate. Upper glume hairs white, or purple. Upper glume apex emarginate; muticous, or awned; 1 -awned. Upper glume awn 0–2 mm long.

FLORETS Basal sterile florets barren; with palea, or without significant palea. Lemma of lower sterile floret similar to upper glume; oblong; 1 length of spikelet; chartaceous; much thinner above; 5 -veined; pubescent, or pilose; hairy below; emarginate; mucronate, or awned. Awn of lower sterile floret 1–2.4 mm long. Palea of lower sterile floret scabrous. Fertile lemma oblong; laterally compressed; 2 mm long; cartilaginous; shiny; without keel; 3 -veined. Lemma margins flat. Palea cartilaginous; without keels.

FLOWER Anthers 3; 1.5 mm long. Stigmas laterally exserted.

DISTRIBUTION Africa: east tropical and south.

NOTES Paniceae. FTEA.
