Chusquea ciliatifolia
HABIT Perennial. Culms scandent; 500 cm long; 2.2–3.2 mm diam.; woody; without nodal roots. Culm-internodes terete; 18.5–23.5 cm long; mottled; distally glabrous. Culm-nodes without obvious supra-nodal ridge. Lateral branches dendroid; infravaginal. Bud complement 5–11. Branch complement several; in an irregular line; with 1 branch dominant; as thick as stem. Culm-sheaths retrorsely scabrous. Leaves 5–8 per branch. Leaf-sheaths keeled; striately veined; glabrous on surface, or pilose; outer margin hairy. Ligule an eciliate membrane; 0.2 mm long. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.1–0.15 cm long; petiole pilose. Leaf-blades linear, or lanceolate; 14.4–17 cm long; 9–10 mm wide; mid-green and glaucous; discolorous with last colour beneath. Leaf-blade venation without cross veins. Leaf-blade surface glabrous. Leaf-blade margins ciliate. Leaf-blade apex acuminate.
INFLORESCENCE Inflorescence a panicle; exserted. Peduncle 1–3 cm long; pilose above.
Panicle open; ovate; 2.5–3 cm long; 1.5–2 cm wide. Primary panicle branches 1–2 cm long. Panicle axis angular; pilose. Panicle branches angular; pilose.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 6.4–6.8 mm long; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.8–1 mm long; membranous; 1-keeled; 3 -veined. Lower glume surface scabrous. Lower glume margins ciliolate. Upper glume ovate; 1–1.2 mm long; membranous; 1-keeled. Upper glume surface scabrous. Upper glume margins ciliolate.
FLORETS Basal sterile florets barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 1.8–2 mm long; 0.33 length of fertile lemma; chartaceous; 9 -veined. Lemma of upper sterile floret ovate; 3–3.4 mm long; chartaceous. Fertile lemma ovate; 5.5–6 mm long; coriaceous; 5 -veined. Lemma surface glabrous. Lemma apex acute. Palea 6.4–6.8 mm long; 4 -veined. Palea surface scabrous. Palea apex with excurrent keel veins.
FLOWER Lodicules 3; 1 mm long; ciliate. Anthers 3; 3 mm long.
DISTRIBUTION South America: Brazil.
