Loxodera strigosa

HABIT Perennial; caespitose. Butt sheaths persistent and investing base of culm; with fibrous dead sheaths. Culms erect; 50–100 cm long. Ligule an eciliate membrane. Leaf-blades 20–40 cm long; 3–5 mm wide. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; 6–8 cm long. Rhachis fragile at the nodes; semiterete; pilose on surface; ciliate on margins. Rhachis internodes columnar; 8–10 mm long. Rhachis internode tip crateriform; with scarious rim.

Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels oblong; flattened; 5 mm long; pubescent.

STERILE SPIKELETS Companion sterile spikelets well-developed; male; elliptic; 7–8 mm long; as long as fertile; persistent. Companion sterile spikelet glumes coriaceous; 5–7 -veined; ciliate on margins; acute; awned; one glume awned; with 7–15 mm long awn. Companion sterile spikelet lemmas 2; enclosed by glumes.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 8 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus cuneate; 1 mm long; bearded; base obtuse; inserted. Spikelet callus hairs 3 mm long.

GLUMES Glumes dissimilar; reaching apex of florets; firmer than fertile lemma. Lower glume elliptic; 1 length of spikelet; chartaceous; purple; without keels; keel-less except near apex; 5 -veined. Lower glume lateral veins ribbed. Lower glume apex acute; muticous, or mucronate. Upper glume elliptic; chartaceous; 3 -veined. Upper glume apex acute.

FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret obovate; 7 mm long; membranous; 3 -veined; ciliate on margins; obtuse. Palea of lower sterile floret 0.9 length of lemma. Fertile lemma lanceolate; 8 mm long; hyaline; 2 -veined. Lemma apex pubescent. Palea hyaline.

DISTRIBUTION Africa: west tropical.
