Eulalia smitinandiana

HABIT Perennial; caespitose. Culms erect; 50–100 cm long. Lateral branches lacking. Ligule an eciliate membrane. Leaf-blades convolute; 15–30 cm long; 4–5 mm wide. Leaf-blade surface glabrous. Leaf-blade margins scaberulous. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 2–3; digitate; 8 cm long. Rhachis fragile at the nodes; ciliate on margins. Rhachis internodes linear; 4 mm long. Rhachis internode tip transverse.

Spikelets in pairs. Fertile spikelets sessile and pedicelled; 2 in the cluster. Pedicels linear; angular; 3.5 mm long; ciliate.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 5 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus bearded; base obtuse; attached transversely.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume elliptic, or oblong; 1 length of spikelet; chartaceous; 2-keeled; keeled above; 6 -veined. Lower glume primary vein scaberulous. Lower glume surface concave; glabrous. Lower glume apex dentate; 2 -fid; awned; 2 -awned. Lower glume awn 4–5 mm long. Upper glume oblong; 1 length of spikelet; 1-keeled; keeled above; 3 -veined. Upper glume margins ciliate. Upper glume apex dentate; 2 -fid; awned; 1 -awned. Upper glume awn 9 mm long.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 3.5 mm long; hyaline; 0 -veined; without midvein; without lateral veins; ciliate on margins; obtuse. Fertile lemma oblong; 4.5 mm long; hyaline; without keel; 1 -veined. Lemma apex lobed; 2 -fid; incised 0.5 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 20–25 mm long overall; with twisted column. Column of lemma awn 12–15 mm long; glabrous. Palea 2 mm long.

FLOWER Anthers 3; 2.5 mm long.

DISTRIBUTION Asia-tropical: Indo-China.
