Eulalia villosa

HABIT Perennial; caespitose. Culms erect; 40–120 cm long. Ligule a ciliolate membrane. Leaf-blades 5–25 cm long; 3–8 mm wide. Leaf-blade surface pubescent. Leaf-blade apex acute.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 3–12; digitate; 5–15 cm long. Rhachis fragile at the nodes; villous on margins. Rhachis hairs white. Rhachis internodes linear. Rhachis internode tip transverse.

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

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 5–7 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus base obtuse; attached transversely.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume elliptic; 1 length of spikelet; cartilaginous; dark brown; 2-keeled; keeled above. Lower glume primary vein ciliate. Lower glume intercarinal veins distinct. Lower glume surface concave; glabrous, or pilose. Lower glume hairs white. Lower glume apex truncate. Upper glume elliptic; 1 length of spikelet. Upper glume surface glabrous, or pilose. Upper glume muticous.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret 4–7 mm long; membranous; much thinner above. Fertile lemma oblong; 3 mm long; hyaline; without keel; 3 -veined. Lemma apex lobed; 2 -fid; incised 0.33–0.5 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 10–20 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.

FLOWER Anthers 3.

DISTRIBUTION Africa: west-central tropical, northeast tropical, east tropical, southern tropical, south, and western Indian ocean. Asia-tropical: India.
