Eulalia leschenaultiana

HABIT Perennial; caespitose. Rhizomes short. Butt sheaths glabrous. Culms erect; 20–45 cm long; wiry. Culm-nodes glabrous. Leaf-sheaths 2–3.5 cm long; glabrous on surface. Leaf-sheath oral hairs ciliate. Ligule a ciliolate membrane. Leaf-blades 3–7 cm long; 2–4 mm wide. Leaf-blade midrib indistinct. Leaf-blade surface glabrous. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence composed of racemes. Peduncle pilose above.

Racemes 2–4; digitate; 3–9 cm long. Rhachis fragile at the nodes; subterete; pilose on surface; villous on margins. Rhachis hairs dark brown. Rhachis internodes linear; 2–2.5 mm long. Rhachis internode tip transverse.

Spikelets in pairs. Fertile spikelets sessile and pedicelled; 2 in the cluster. Pedicels linear; angular; villous; with dark brown hairs.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; 3.5 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus pubescent; base obtuse; attached transversely.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume elliptic; 1 length of spikelet; cartilaginous; 2-keeled; keeled above; 2 -veined. Lower glume surface pilose. Lower glume margins ciliate. Lower glume apex truncate. Upper glume lanceolate; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume surface pilose; hairy above. Upper glume apex truncate; muticous.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret linear; hyaline; 2 -veined; ciliate on margins. Fertile lemma lanceolate; 1.4 mm long; hyaline; without keel. Lemma margins ciliolate. Lemma apex lobed; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 12.5 mm long overall; with twisted column. Column of lemma awn 6 mm long; hispidulous. Palea 0.5 mm long; hyaline.

FLOWER Anthers 3; 2 mm long; brown, or red.

FRUIT Caryopsis with adherent pericarp.

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