Descriptions

Morphology General Habit
Perennial. Culms woody; without nodal roots. Culm-internodes terete. Lateral branches dendroid. Branch complement many; in a clump; thinner than stem. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 1-3 mm long; obtuse. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.2-0.4 cm long. Leaf-blades lanceolate; 9.2-12 cm long; 8-13 mm wide. Leaf-blade venation without cross veins. Leaf-blade surface glabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; without bracts, or bracteate at pedicel base; embraced at base by subtending leaf. Panicle open; linear; 7-20.5 cm long. Primary panicle branches appressed; 5-7 cm long. Panicle axis angular; scabrous. Panicle branches angular; scabrous; glabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 1-10 mm long; scabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 10-13.3 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 elliptic; laterally compressed; 10-13.3 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; 2.2-3.8 mm long; membranous; without keels; 1-3 -veined. Lower glume lateral veins absent, or obscure. Lower glume surface scabrous. Lower glume apex acute. Upper glume ovate; 4-6.6 mm long; 0.33-0.5 length of adjacent fertile lemma; membranous; without keels; 3-7 -veined. Upper glume surface scabrous. Upper glume apex acute.
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; 5.9-8.7 mm long; 0.75 length of fertile lemma; chartaceous; 5-7 -veined; scabrous; acute; mucronate. Lemma of upper sterile floret ovate; 9.3-11.6 mm long; chartaceous; scabrous; acute; mucronate. Fertile lemma ovate; 9-10.6 mm long; coriaceous; without keel; 7-9 -veined. Lemma surface scabrous. Lemma apex apiculate. Palea 7.6-10.2 mm long; 2-4 -veined.
