Chusquea anelytroides
HABIT Perennial. Culms 400–1000 cm long; 20–30 mm diam.; woody; without nodal roots. Culm-internodes terete; solid; smooth. Lateral branches dendroid. Branch complement several. Leaves 5–15 per branch. Leaf-sheaths striately veined; scaberulous; glabrous on surface. Leaf-sheath auricles erect. Ligule a ciliolate membrane; 3–4 mm long; obtuse. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole pubescent. Leaf-blades deciduous at the ligule; lanceolate, or ovate; 6–15 cm long; 8–25 mm wide. Leaf-blade midrib prominent beneath. Leaf-blade surface glabrous. Leaf-blade margins scabrous.
INFLORESCENCE Inflorescence a panicle; embraced at base by subtending leaf.
Panicle open; pyramidal; 15 cm long; contracted about primary branches. Primary panicle branches 1–12 cm long; bearing spikelets almost to the base. Panicle axis pubescent. Panicle branches bearing approximate spikelets; puberulous.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels puberulous.
FERTILE SPIKELETS Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; acute; 7 mm long; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 0.2–0.5 mm long; 1 length of upper glume; membranous. Upper glume lanceolate; 0.2–0.5 mm long; 0.02–0.05 length of adjacent fertile lemma.
FLORETS Basal sterile florets similar; barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret lanceolate; 4–5 mm long; 0.66–0.75 length of spikelet; chartaceous. Lemma of upper sterile floret lanceolate; 5–6 mm long; 1.2–1.3 length of lower sterile floret; chartaceous; acute. Fertile lemma lanceolate; 5–6 mm long; coriaceous; without keel; 7 -veined. Lemma surface scaberulous. Lemma apex acute; muticous, or mucronate. Palea keels scaberulous.
FLOWER Lodicules 3; membranous; ciliate. Anthers 3. Stigmas 2.
FRUIT Caryopsis with adherent pericarp.
DISTRIBUTION South America: Brazil.
