Descriptions

Morphology General Habit
Perennial. Culms scandent; 3-4 mm diam.; woody; without nodal roots. Culm-internodes terete; solid; 10-17 cm long; scaberulous. Lateral branches dendroid. Branch complement three. Leaf-sheaths keeled (above); striately veined; glabrous on surface, or pubescent. Ligule an eciliate membrane; 3 mm long; obtuse. Collar with external ligule. Leaf-blade base cordate; with a brief petiole-like connection to sheath; petiole 0.2-0.3 cm long; petiole glabrous, or pubescent. Leaf-blades deciduous at the ligule; oblong; 10-14 cm long; 14-20 mm wide. Leaf-blade venation with obscure cross veins. Leaf-blade surface glabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; embraced at base by subtending leaf. Panicle open; pyramidal; 7-15 cm long. Primary panicle branches reflexed; 9 cm long. Panicle branches pubescent. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; acuminate; 8 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 lanceolate; subterete; acuminate; 8 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume orbicular; 0.2-0.5 mm long; 1 length of upper glume; membranous; without keels. Lower glume apex obtuse. Upper glume orbicular; 0.02-0.05 length of adjacent fertile lemma; without keels. Upper glume apex obtuse.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets similar; barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret lanceolate; 6 mm long; chartaceous; acute; mucronate. Lemma of upper sterile floret lanceolate; 7 mm long; chartaceous; acute; mucronate. Fertile lemma lanceolate; 8 mm long; coriaceous; without keel. Lemma apex acuminate. Palea 1 length of lemma.
Morphology Reproductive morphology Flowers
Lodicules 3; membranous; veined; ciliate. Anthers 3. Stigmas 2.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; apex unappendaged.
