Eulalia conjugata

HABIT Annual. Butt sheaths glabrous. Culms 30–60 cm long. Culm-internodes smooth. Culm-nodes glabrous. Leaf-sheaths glabrous on surface. Ligule a ciliolate membrane. Leaf-blades 15–25 cm long; 4 mm wide; flaccid. Leaf-blade surface pubescent; sparsely hairy; hairy adaxially.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 2–6; paired, or digitate; 2.5–7.5 cm long. Rhachis fragile at the nodes; ciliate on margins. Rhachis internodes linear. Rhachis internode tip transverse.

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

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus pilose; base obtuse; attached transversely. Spikelet callus hairs white.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate; 1 length of spikelet; cartilaginous; 2-keeled; keeled above. Lower glume primary vein ciliate. Lower glume surface convex, or flat. Lower glume apex dentate; 2 -fid. Upper glume elliptic; 1 length of spikelet. Upper glume margins ciliate. Upper glume apex obtuse; muticous.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 3 mm long; hyaline; ciliate on margins; obtuse. Fertile lemma oblong; 2.5 mm long; hyaline; without keel. Lemma apex lobed; 2 -fid; incised 0.5 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 13–19 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.

FLOWER Anthers 3.

DISTRIBUTION Asia-tropical: India, Indo-China, and Malesia.
