Morphology General Habit
Perennial. Culms erect (1), or geniculately ascending (1); 20-52.5-90 cm long. Lateral branches lacking (1/1). Ligule a fringe of hairs. Leaf-blades stiff (1), or firm (1).
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes; terminal (1), or terminal and axillary (1); subtended by an unspecialized leaf-sheath (1), or an inflated leaf-sheath (1). Racemes paired (1), or digitate (1). Rhachis fragile at the nodes; flattened. Rhachis internodes linear. Rhachis internode tip oblique. Spikelets in pairs. Fertile spikelets sessile and pedicelled; 2 in the cluster. Pedicels linear.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3.5-4.625-5.5 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus bearded.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3.5-4.625-5.5 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus bearded.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes exceeding apex of florets; firmer than fertile lemma. Lower glume elliptic (1), or oblong (1); chartaceous; without keels; 5 -veined (1), or 7 -veined (1). Lower glume lateral veins ribbed. Lower glume surface villous. Lower glume apex dentate; 2-3 -fid. Upper glume lanceolate; chartaceous; without keels; 3 -veined, or 4-5 -veined (1). Upper glume surface villous. Upper glume apex dentate; 2 -fid; mucronate (1), or awned; 1 -awned.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets male; with palea. Lemma of lower sterile floret oblong; hyaline; 0-1 -veined (1). Fertile lemma linear; hyaline; without keel; 1 -veined. Lemma surface smooth (1), or scaberulous (1). Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate. Palea 0.7-0.725-0.8 length of lemma; hyaline; 2 -veined (1/1).
