Eulaliopsis sykesii
HABIT Perennial; caespitose. Butt sheaths woolly; persistent and investing base of culm; with compacted dead sheaths. Culms geniculately ascending; 20–40 cm long; 3–4 -noded. Culm-nodes glabrous. Lateral branches lacking. Leaf-sheath oral hairs bearded. Ligule a fringe of hairs. Leaf-blades flat, or conduplicate; 15–20 cm long; 2 mm wide. Leaf-blade surface pilose; hairy on both sides; with tubercle-based hairs. Leaf-blade margins scabrous.
INFLORESCENCE Inflorescence composed of racemes; terminal; subtended by an inflated leaf-sheath.
Racemes 2; paired; 2.5 cm long. Rhachis fragile at the nodes; flattened; ciliate on margins. Rhachis internodes linear; 1.5–2 mm long. Rhachis internode tip oblique.
Spikelets in pairs. Fertile spikelets sessile and pedicelled; 2 in the cluster. Pedicels linear; flattened; 1.5–2 mm long; pubescent.
FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 5–5.5 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus bearded. Spikelet callus hairs dark brown; 1 length of spikelet.
GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; chartaceous; pallid; without keels; 7 -veined. Lower glume lateral veins ribbed. Lower glume surface villous; hairy below. Lower glume hairs red. Lower glume apex dentate; 2–3 -fid. Upper glume lanceolate; chartaceous; without keels; 3 -veined. Upper glume primary vein scabrous. Upper glume surface villous; hairy below. Upper glume hairs red. Upper glume apex dentate; 2 -fid; awned; 1 -awned. Upper glume awn 8–8.5 mm long.
FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret oblong; 3.5 mm long; hyaline; 1 -veined; pilose; hairy at apex. Palea of lower sterile floret pilose; adorned on keels (above). Fertile lemma linear; 3 mm long; hyaline; without keel; 1 -veined. Lemma surface scaberulous; rough above. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 18–20 mm long overall; with twisted column. Column of lemma awn 5 mm long. Palea orbicular; 0.7–0.8 length of lemma; hyaline; 2 -veined. Palea apex ciliate.
FLOWER Anthers 3; 2–3.5 mm long.
DISTRIBUTION Asia-tropical: India.
NOTES Andropogoneae. Bor.
