Descriptions

Morphology General Habit
Annual; caespitose. Culms erect, or geniculately ascending; 9-13 cm long. Leaf-sheath oral hairs ciliate. Leaf-sheath auricles falcate. Ligule an eciliate membrane. Leaf-blades 3-6 cm long; 2-3 mm wide. Leaf-blade surface pubescent; hairy on both sides.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes; deciduous as a whole. Racemes 1; single; lanceolate, or ovate; bilateral; 1-2 cm long; bearing few fertile spikelets; bearing 2-7 fertile spikelets on each. Rhachis tough. Spikelet packing broadside to rhachis. Spikelets solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Basal sterile spikelets rudimentary; 2-3 in number. Spikelets comprising 2-3 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 5-7 mm long; falling entire; deciduous with accessory branch structures.
Sterile
Basal sterile spikelets rudimentary; 2-3 in number.
Fertile
Spikelets comprising 2-3 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 5-7 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes similar; shorter than spikelet. Lower glume oblong, or obovate; 3-5 mm long; 1 length of upper glume; coriaceous; without keels; 7-9 -veined. Lower glume lateral veins distinct; ribbed. Lower glume surface scabrous; rough on veins. Lower glume apex dentate; truncate; awned; 2-3 -awned. Lower glume awn 9-24 mm long. Upper glume oblong, or obovate; 3-5 mm long; 0.66 length of adjacent fertile lemma; coriaceous; without keels; 7-9 -veined. Upper glume lateral veins distinct; ribbed; parallel at apex. Upper glume surface scabrous; rough on veins. Upper glume apex dentate; 2-3 -fid; truncate; awned; 2-3 -awned. Upper glume awn 9-25 mm long.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; 4.5-7.5 mm long; coriaceous; without keel; 5 -veined. Lemma apex entire, or erose; emarginate, or truncate; muticous, or awned only on distal spikelets (shortly); 1 -awned. Principal lemma awn 20-120 mm long overall. Palea 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2. Ovary pubescent on apex.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; hairy at apex. Disseminule comprising a inflorescence.
