Eulalia filifolia

HABIT Perennial. Culms 17–30 cm long; 3–4 -noded. Culm-internodes distally glabrous. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 0.1 mm long. Leaf-blades filiform, or linear; involute; 5–17 cm long; 1 mm wide. Leaf-blade surface puberulous; hairy adaxially.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1–3; single, or paired, or digitate; 2–4.5 cm long. Rhachis tough; ciliate on margins. Rhachis internodes linear; 1.3 mm long.

Spikelets in pairs. Fertile spikelets pedicelled; 2 in the cluster. Pedicels linear; unequal.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 2 mm long; falling entire; deciduous from the base. Spikelet callus square; pilose, or bearded; base obtuse; attached transversely. Spikelet callus hairs 0.3–1.7 mm long.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate; 1 length of spikelet; chartaceous; light brown; 2-keeled. Lower glume surface pilose. Lower glume apex obtuse. Upper glume lanceolate; chartaceous; 1-keeled. Upper glume mucronate.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 1 mm long; hyaline; 0 -veined; without midvein; without lateral veins; obtuse. Fertile lemma linear; 1 mm long; hyaline; without keel; 1 -veined. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 6–7 mm long overall; with a straight or slightly twisted column. Column of lemma awn glabrous. Palea absent or minute.

FLOWER Anthers 3; 0.7 mm long.
