Lepturus perrieri

HABIT Annual; caespitose. Culms erect; 35–40 cm long. Culm-internodes smooth; distally glabrous. Leaf-sheaths mostly shorter than adjacent culm internode. Ligule a ciliolate membrane. Leaf-blades convolute; 7–11 cm long.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; smoothly terete; bilateral; 3.8–4 cm long. Rhachis fragile at the nodes; subcylindrical and excavated; 1–2 mm wide; glabrous on surface; glabrous on margins. Spikelet packing adaxial; opposite; regular; 2 -rowed. Rhachis internodes oblong; 5.2–5.5 mm long. Rhachis internode tip transverse; flat.

Spikelets sunken; solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets. Spikelets oblong; dorsally compressed; 4–4.2 mm long; falling entire; deciduous with accessory branch structures.

GLUMES Glumes one the lower absent or obscure (but terminal spikelet with 2 glumes 5mm long); exceeding apex of florets; firmer than fertile lemma. Upper glume lanceolate; 4–4.2 mm long; coriaceous; without keels. Upper glume apex acute; muticous.

FLORETS Fertile lemma lanceolate; 3.2–3.5 mm long; coriaceous; without keel; 3 -veined. Lemma apex obtuse. Palea 1 length of lemma.

DISTRIBUTION Africa: western Indian ocean.
