Lasiacis maculata

HABIT Perennial; caespitose. Culms scandent; 100–1000 cm long (long); 4–10 mm diam.; woody. Culm-internodes hollow. Culm-nodes glabrous. Ligule a ciliolate membrane; 0.5–1 mm long. Leaf-blades linear, or lanceolate; 6–23 cm long; 6–46 mm wide. Leaf-blade surface pubescent.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 5–35 cm long.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or obovate; tilted on the pedicel; dorsally compressed; 3–4.3 mm long; falling entire.

GLUMES Glumes dissimilar; reaching apex of florets; thinner than fertile lemma; shiny. Lower glume oblate; 1.2–2.7 mm long; 0.4–0.6 length of spikelet; membranous; black; without keels; 7–11 -veined. Lower glume surface woolly; hairy at apex. Lower glume apex obtuse. Upper glume ovate; 1 length of adjacent fertile lemma; membranous; black; without keels; 9–13 -veined. Upper glume surface woolly; hairy at apex. Upper glume apex obtuse.

FLORETS Basal sterile florets male, or barren; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 9–11 -veined; woolly; hairy at apex; obtuse. Fertile lemma ovate; dorsally compressed; 3–4.3 mm long; indurate; dark brown; shiny; without keel. Lemma margins involute. Lemma apex obtuse; with a shallow excavation and woolly. Palea indurate. Palea apex pubescent.

DISTRIBUTION North America: Mexico. South America: Mesoamericana, Caribbean, northern South America, western South America, Brazil, and southern South America.
