Lasiurus scindicus

HABIT Perennial; caespitose. Rhizomes short; scaly; hairy. Culms 30–100 cm long. Ligule a fringe of hairs. Leaf-blades flat, or convolute; 10–30 cm long; 1–3 mm wide; glaucous. Leaf-blade apex attenuate; filiform.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; 5–12 cm long. Rhachis fragile at the nodes; flattened; glabrous on surface, or pubescent on surface, or villous on surface; ciliate on margins. Rhachis internodes cuneate. Rhachis internode tip transverse; flat.

Spikelets in threes. Fertile spikelets sessile; (1–)2 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels linear; flattened; 3–3.5 mm long; glabrous, or pubescent, or villous; tip rectangular.

STERILE SPIKELETS Companion sterile spikelets well-developed; male; lanceolate; 5–7 mm long; shorter than fertile; deciduous with the fertile. Companion sterile spikelet callus truncate. Companion sterile spikelet glumes coriaceous; ciliate on margins; dentate; acuminate; mucronate. Companion sterile spikelet lemmas 2; enclosed by glumes.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 7–9 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus bearded; base truncate; with central peg; attached transversely. Spikelet callus hairs 0.3–0.5 length of spikelet.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate; 1 length of spikelet; coriaceous; 2-keeled; keeled above; keeled laterally. Lower glume primary vein ciliate. Lower glume surface flat. Lower glume apex entire, or dentate; 2 -fid; caudate. Upper glume lanceolate; membranous; 1-keeled; 5 -veined. Upper glume primary vein ciliate. Upper glume apex acute.

FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret oblong; 4 mm long; hyaline; 3 -veined; acute. Fertile lemma oblong; hyaline; without keel; 3 -veined. Lemma apex acute. Palea hyaline.

DISTRIBUTION Africa: north, west tropical, and northeast tropical. Asia-temperate: western Asia and Arabia. Asia-tropical: India.
