Morphology General Habit
Perennial; mat forming. Rhizomes elongated. Culms geniculately ascending, or decumbent; 15-90 cm long. Ligule a fringe of hairs. Leaf-blades flat, or conduplicate; 7-15 cm long; 2-6 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; oblong, or ovate, or globose; 2-12 cm long; 1-2 cm wide. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis angular; smooth; pilose; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1(-4) in the cluster. Involucre composed of bristles; cuneate; 40-70 mm long; base bluntly stipitate (1mm). Involucral bristles deciduous with the fertile spikelets; numerous; with longest bristle scarcely emergent; 40-70 mm long; terete; flexible; plumose.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; cuspidate; 9-14 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; cuspidate; 9-14 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes one the lower absent or obscure, or two; dissimilar; shorter than spikelet; thinner than fertile lemma. Lower glume oblate; 0.5-1 mm long; 0.05-0.1 length of spikelet; membranous; without keels; 0-1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume lanceolate, or ovate; 3.5-6 mm long; 0.33-0.5 length of spikelet; membranous; without keels; 1-3 -veined. Upper glume apex acute, or acuminate.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets male, or barren; with palea, or without significant palea. Lemma of lower sterile floret ovate; 1 length of spikelet; membranous; 7-11 -veined; scaberulous; rough on veins; acute, or acuminate. Fertile lemma lanceolate; 9-14 mm long; membranous; without keel; 5-7 -veined. Lemma margins flat. Lemma apex acute. Palea membranous.
