Cynodon nlemfuensis

HABIT Perennial; mat forming. Rhizomes absent. Stolons present; with alternating elongated and bunched internodes. Culms geniculately ascending; 30–60 cm long; 1–3 mm diam.; firm. Ligule a ciliolate membrane; 0.3 mm long. Leaf-blades flat; 5–16 cm long; 2–6 mm wide; stiff, or firm; mid-green, or glaucous. Leaf-blade surface scaberulous; glabrous, or pilose; sparsely hairy.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 4–8(–13); digitate; straight, or flexuous; unilateral; 4–7(–10) cm long. Rhachis flattened. Spikelet packing broadside to rhachis; regular; 2 -rowed.

Spikelets appressed; solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; compressed strongly; 2–3 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; subequal in width; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 1 length of upper glume; herbaceous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 0.5–0.8 length of adjacent fertile lemma; herbaceous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma ovate; laterally compressed; 2–3 mm long; cartilaginous; mid-green, or red; keeled; 3 -veined. Lemma midvein pubescent, or ciliate. Lemma apex acute. Palea 2 -veined. Palea keels eciliate.

FRUIT Caryopsis with adherent pericarp.
