    Habit
    Perennial. Stolons present. Culms erect; 7-35 cm long; wiry. Lateral branches sparse. Ligule a fringe of hairs. Leaf-blades stiff. Leaf-blade apex pungent.
    Inflorescences
    Inflorescence composed of racemes. Racemes single, or borne along a central axis; appressed; bearing few fertile spikelets; bearing 1-5 fertile spikelets on each. Rhachis subterete. Spikelet packing broadside to rhachis; lax. Spikelets ascending; solitary. Fertile spikelets sessile, or pedicelled. Pedicels linear.
    Spikelets
    Spikelets comprising 4-14 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 5-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident.
    Fertile
    Spikelets comprising 4-14 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 5-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate, or elliptic, or oblong, or ovate; 0.6-0.8 length of upper glume; hyaline; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 0.6-0.8 length of adjacent fertile lemma; hyaline; without keels; 1 -veined. Upper glume apex obtuse, or acute.
    Florets
    Fertile lemma oblong; laterally compressed; membranous; without keel; 3 -veined. Lemma lateral veins stopping well short of apex. Lemma apex emarginate, or obtuse. Palea 0.9 length of lemma; 2 -veined. Palea apex entire. Apical sterile florets resembling fertile though underdeveloped.
