Morphology General Habit
Perennial. Culms arching, or scandent; pendulous at the tip; 700-900 cm long; 15-20 mm diam.; woody; without nodal roots. Culm-internodes channelled; 20-30 cm long; distally glabrous, or pilose. Lateral branches dendroid; infravaginal. Bud complement 40-60. Bud prophyll 30-50 mm long. Branch complement many; in a clump; thinner than stem. Culm-sheaths persistent; 17.6-45 cm long; concolorous; antrorsely scabrous; glabrous, or hispid; hairy at the base. Culm-sheath ligule 0.2-0.5 mm high. Culm-sheath blade lanceolate; indistinctly demarcated from sheath; erect; 2.2-8 cm long; scabrid; attenuate. Ligule an eciliate membrane; 0.5-1 mm long; truncate. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.1-0.3 cm long. Leaf-blades lanceolate; 4.4-12.2 cm long; 3-8 mm wide. Leaf-blade venation without cross veins. Leaf-blade surface glabrous, or pilose; hairy abaxially.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; without bracts, or bracteate at branch bases, or bracteate at pedicel base. Panicle open; linear; 3.5-8 cm long. Primary panicle branches appressed; 1-2 cm long. Panicle axis angular; scabrous. Panicle branches angular; scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 1-4 mm long; scabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 7.8-10 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 7.8-10 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 1.8-2.8 mm long; membranous; without keels; 1-3 -veined. Lower glume lateral veins absent, or distinct. Lower glume surface asperulous. Lower glume apex acute. Upper glume ovate; 4-5.1 mm long; 0.5 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume surface asperulous. Upper glume apex acute; mucronate.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 4.7-6.2 mm long; 0.75 length of fertile lemma; chartaceous; 7-9 -veined; scaberulous; acute. Lemma of upper sterile floret ovate; 7.2-8.9 mm long; chartaceous; scabrous; acuminate. Fertile lemma ovate; 6.8-8.4 mm long; coriaceous; without keel; 7-9 -veined. Lemma surface scaberulous. Lemma apex apiculate. Palea 6.3-8.2 mm long; 6 -veined.
