Morphology General Habit

Annual. Culms erect (1), or geniculately ascending, or decumbent (2); 7-15.83-30 cm long. Ligule an eciliate membrane.

Morphology Reproductive morphology Inflorescences

Inflorescence a panicle (2), or composed of racemes (2). Panicle open (2/2). Racemes single (2/2); linear (1/2), or oblong (1/2); unilateral (2/2). Rhachis angular (2/2). Spikelet packing broadside to rhachis (2/2); 2 -rowed (1/1). Spikelets appressed; solitary. Fertile spikelets sessile (1), or pedicelled (2). Pedicels oblong (2/2).

Morphology Reproductive morphology Inflorescences Spikelets

Spikelets comprising 3-4 fertile florets (1), or 5 fertile florets (2), or 6-7 fertile florets (1), or 8-20 fertile florets (2), or 21-30 fertile florets (1); with diminished florets at the apex. Spikelets elliptic (1), or oblong; laterally compressed; 5-12.16-28 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes glabrous (1), or pubescent (2).

Fertile

Spikelets comprising 3-4 fertile florets (1), or 5 fertile florets (2), or 6-7 fertile florets (1), or 8-20 fertile florets (2), or 21-30 fertile florets (1); with diminished florets at the apex. Spikelets elliptic (1), or oblong; laterally compressed; 5-12.16-28 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes glabrous (1), or pubescent (2).

Morphology Reproductive morphology Inflorescences Bracts Glume

Glumes persistent; shorter than spikelet. Lower glume oblong (2), or ovate (1); 0.75-0.775-0.9 length of upper glume; coriaceous; 1-keeled; 3 -veined. Lower glume apex obtuse (2), or acute (1). Upper glume oblong (2), or ovate (1); 0.7-0.75-0.8 length of adjacent fertile lemma; coriaceous; 1-keeled; 3 -veined. Upper glume lateral veins without ribs (1), or ribbed (2). Upper glume apex obtuse (2), or acute (1).

Morphology Reproductive morphology Flowers Florets

Fertile lemma ovate; ovate in profile (1/1); coriaceous; of similar consistency on margins (2), or much thinner on margins (1); keeled; 5 -veined (2), or 7 -veined (1). Lemma midvein without distinctive roughness (1), or scaberulous (2). Lemma lateral veins with distinct primaries but obscure intermediates (2/2). Lemma surface glabrous (1), or pubescent (2); with capitate hairs (2/2). Lemma apex obtuse (2), or acute (1); muticous, or mucronate (1). Palea 2 -veined. Palea keels wingless (2), or winged (1); smooth (2), or scaberulous (1); eciliate (2), or ciliolate (1). Apical sterile florets resembling fertile though underdeveloped.

Morphology Reproductive morphology Flowers

Anthers 3. Ovary glabrous.

Morphology Reproductive morphology Fruits

Caryopsis with adherent pericarp; oblong (2/2); dorsally compressed (2/2); concavo-convex (1/1). Embryo 0.33 length of caryopsis. Hilum punctiform.

Distribution

Europe (1), or Africa, or Temperate Asia (1).
