Morphology General Habit
Perennial; caespitose. Culms erect; 30-110 cm long; 2-5 -noded. Leaves cauline. Leaf-sheaths glabrous on surface, or pubescent. Leaf-sheath oral hairs lacking. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 0.5-1.5 mm long; erose; truncate. Leaf-blades 10-30 cm long; 4-13 mm wide. Leaf-blade surface ungrooved; scaberulous; glabrous, or pilose. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 1; single; drooping, or erect; bilateral; 5-20 cm long. Rhachis flattened; scabrous on margins. Spikelet packing broadside to rhachis; regular; 2 -rowed. Spikelets appressed; solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or oblong; laterally compressed; 10-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Spikelet callus glabrous; base truncate. Rhachilla internodes eventually visible between lemmas.
Fertile
Spikelets comprising 2-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or oblong; laterally compressed; 10-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Spikelet callus glabrous; base truncate. Rhachilla internodes eventually visible between lemmas.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; subequal in width; shorter than spikelet. Lower glume lanceolate; 7-10 mm long; 1 length of upper glume; coriaceous; without keels; 2-5 -veined. Lower glume lateral veins ribbed. Lower glume surface scabrous. Lower glume apex acuminate; muticous to mucronate. Upper glume lanceolate; 7-10 mm long; 0.7-0.8 length of adjacent fertile lemma; coriaceous; without keels; 2-5 -veined. Upper glume lateral veins ribbed. Upper glume surface scabrous; rough on veins. Upper glume apex acuminate; muticous to mucronate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate to oblong; 9-13 mm long; coriaceous; without keel; 5 -veined. Lemma apex acute; awned; 1 -awned. Principal lemma awn straight, or flexuous; 7-20 mm long overall; limb scabrous. Palea lanceolate; 1 length of lemma; 2 -veined. Palea keels scabrous. Palea apex truncate. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; elliptic; membranous. Anthers 3; 2-3 mm long. Stigmas 2; protandrous; laterally exserted. Ovary pubescent on apex.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; fusiform; isodiametric; estipitate; sulcate on hilar side; smooth; apex unappendaged. Embryo 0.2 length of caryopsis. Hilum linear; 0.9 length of caryopsis. Endosperm farinose.
