Morphology General Habit
Perennial; caespitose. Rhizomes absent, or elongated. Stolons present. Culms geniculately ascending, or decumbent, or prostrate; 15-75 cm long; 1-4 -noded; without nodal roots, or rooting from lower nodes. Culm-internodes smooth. Leaf-sheaths without keel; smooth, or scaberulous. Ligule an eciliate membrane; 1-5 mm long; acute. Leaf-blades flat, or convolute; 2-15 cm long; 1-3 mm wide. Leaf-blade surface ribbed; scaberulous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open, or contracted; lanceolate, or ovate; 2-10 cm long; 1-7 cm wide. Primary panicle branches whorled at most nodes. Panicle branches capillary; terete; scaberulous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; terete; 1-3 mm long.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate, or oblong; laterally compressed; 1.7-3.3 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.
Fertile
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate, or oblong; laterally compressed; 1.7-3.3 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; exceeding apex of florets; firmer than fertile lemma; shiny; gaping. Lower glume lanceolate; 1-1.1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 1.5 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scaberulous (above). Upper glume lateral veins absent. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong, or ovate; 1.1-2.1 mm long; hyaline; without keel; 4-5 -veined. Lemma apex truncate; muticous, or awned; 1 -awned. Principal lemma awn dorsal; arising 0.2 way up back of lemma; geniculate; 2-4.5 mm long overall; with twisted column. Palea oblong; 0.1-0.25 length of lemma; hyaline; 2 -veined. Palea apex obtuse.
Morphology Reproductive morphology Flowers
Lodicules 2; lanceolate; membranous. Anthers 3; 1-1.5 mm long. Stigmas 2; laterally exserted.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; ellipsoid; isodiametric; biconvex; estipitate; without sulcus; smooth; apex unappendaged. Embryo 0.2 length of caryopsis. Hilum linear; 0.9 length of caryopsis. Endosperm farinose.
Distribution
Europe: northern, central, southwestern, southeastern, and eastern. Africa: Macaronesia and northeast tropical. Asia-temperate: western Asia, China, and eastern Asia. Asia-tropical: India. Pacific: north-central. North America: Subarctic, eastern Canada, northeast USA, and southeast USA. South America: Caribbean. Antarctic: Subantarctic islands.
