Morphology General Habit
Perennial; caespitose; clumped densely. Rhizomes short. Butt sheaths glabrous. Culms erect; 5-20 cm long; 1-2 -noded. Culm-internodes distally glabrous. Leaves mostly basal. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 0.3-1 mm long; erose; truncate. Leaf-blades flat, or convolute; 1-8 cm long; 0.5-2.5 mm wide. Leaf-blade surface glabrous. Leaf-blade margins smooth, or scaberulous. Leaf-blade apex obtuse to acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; subtended by an unspecialized leaf-sheath, or an inflated leaf-sheath. Panicle capitate; elliptic, or ovate; 0.8-2 cm long; 0.8-1.4 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis. Panicle axis with rounded ribs. Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 3.5-4 mm long; falling entire.
Fertile
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 3.5-4 mm long; falling entire.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes free, or connate along margins below; 0-0.1 of their length connate; similar; exceeding apex of florets. Lower glume linear; 3.5-4 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume primary vein ciliate. Lower glume surface villous. Lower glume apex acute; awned; 1 -awned. Lower glume awn 0.8-2 mm long; ciliate. Upper glume linear; 3.5-4 mm long; 1.5 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein ciliate. Upper glume surface villous. Upper glume apex acute; awned; 1 -awned. Upper glume awn 0.8-2 mm long; ciliate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; 2.4-3 mm long; membranous; keeled; 5 -veined. Lemma surface pubescent; hairy above. Lemma margins connate below. Lemma apex obtuse; awned; 1 -awned. Principal lemma awn dorsal; arising 0.1-0.25 way up back of lemma; geniculate; 7-9 mm long overall; with twisted column. Palea absent or minute.
Morphology Reproductive morphology Flowers
Lodicules absent. Anthers 3; 1-1.4 mm long; yellow, or purple. Stigmas terminally exserted; pubescent. Ovary glabrous.
