Morphology General Habit
Annuals or perennials
Morphology Leaves
Leaf-blades flat, linear to narrowly lanceolate; ligule membranous
Morphology Reproductive morphology Inflorescences
Inflorescence a loose cylindrical raceme-like panicle upon a slender peduncle, borne in the axils of the upper leaves; rhachis slender, angular, the spikelets shortly pedicellate and borne singly
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets lanceolate, dorsally compressed; glumes reduced to small (0.1–0.6 mm.) rotund scales; lower floret represented by an awned (rarely awnless) lemma as long as the spikelet; upper lemma membranous, a little shorter than the spikelet, its thin margins almost meeting at the back, enclosing a narrow palea half as long as the lemma
Morphology Reproductive morphology Fruits
Caryopsis oblong, dorsally compressed.

Morphology Reproductive morphology Inflorescences
Synflorescence simple, or compound (1). Inflorescence composed of racemes; terminal (3), or terminal and axillary (1). Racemes single; multilateral. Rhachis angular. Spikelet packing abaxial. Spikelets ascending; solitary. Fertile spikelets pedicelled. Pedicels linear (1/2), or oblong (1/2).
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 2-3.687-5.5 mm long; falling entire.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 2-3.687-5.5 mm long; falling entire.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes shorter than spikelet; thinner than fertile lemma. Lower glume orbicular; 0.5-0.75-1 length of upper glume; hyaline; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex truncate, or obtuse. Upper glume orbicular; hyaline; without keels; 0 -veined. Upper glume apex emarginate (1), or truncate, or obtuse.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret elliptic; membranous; 5 -veined; obtuse (1), or acute (1), or acuminate (3); muticous (1), or awned. Fertile lemma elliptic (3), or ovate (1); membranous; without keel; 5 -veined (1/1). Lemma margins covering most of palea. Lemma apex truncate (1), or obtuse (1), or acute (3); muticous (1), or mucronate. Palea 0.5 length of lemma; hyaline; without keels.
