Morphology General Habit
Perennial; caespitose. Rhizomes short. Culms geniculately ascending, or decumbent; 45-60 cm long; woody; rooting from lower nodes. Lateral branches ample. Leaf-sheaths glabrous on surface. Ligule a fringe of hairs. Leaf-blades flat, or conduplicate, or involute; 10-20 cm long; 3-5 mm wide. Leaf-blade surface smooth, or scaberulous; rough adaxially; glabrous, or pilose; sparsely hairy; hairy adaxially.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear; 3-7.5 cm long; 0.5-0.8 cm wide. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis angular; scaberulous; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1 in the cluster. Involucre composed of bristles; cuneate; 10-20 mm long; base obtuse; base villous. Involucral bristles deciduous with the fertile spikelets; numerous; 15-30 in principal whorl; with one conspicuously longer bristle; 14-24 mm long; terete; flexible; ciliate.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acute; 3.5-4 mm long; falling entire; deciduous with accessory branch structures.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acute; 3.5-4 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate, or ovate; 1-2 mm long; 0.33-0.5 length of spikelet; hyaline; without keels; 0-1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse, or acute. Upper glume lanceolate; 2.5-3 mm long; 0.75 length of spikelet; membranous; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute, or acuminate.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; 1 length of spikelet; membranous; 3-5 -veined; scaberulous; rough above; acute, or acuminate; mucronate. Fertile lemma oblong; 3.5-4 mm long; membranous; without keel; 3-5 -veined. Lemma margins flat. Lemma apex acute. Palea 1 length of lemma; membranous.
Morphology Reproductive morphology Flowers
Lodicules absent. Anthers 3; 2 mm long; anther tip smooth. Styles connate below; 1 of their length connate.
