Aegilops neglecta
HABIT Annual; caespitose. Culms geniculately ascending; 25–35 cm long. Leaf-sheath oral hairs ciliate. Leaf-sheath auricles falcate. Ligule an eciliate membrane. Leaf-blades 2–6 cm long; 2.5–3 mm wide. Leaf-blade surface pilose. Leaf-blade margins ciliate.
INFLORESCENCE Inflorescence composed of racemes; deciduous as a whole.
Racemes 1; single; obovate; bilateral; 3–6 cm long; bearing few fertile spikelets; bearing 2(–3) fertile spikelets on each. Rhachis tough. Spikelet packing broadside to rhachis.
Spikelets solitary. Fertile spikelets sessile.
STERILE SPIKELETS Basal sterile spikelets rudimentary; 3 in number.
Apical sterile spikelets barren; 1–2 in number; 1–2 mm long.
FERTILE SPIKELETS Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 10–11 mm long; falling entire; deciduous with accessory branch structures.
GLUMES Glumes similar; shorter than spikelet. Lower glume elliptic; gibbous; 9–10 mm long; 1 length of upper glume; coriaceous; without keels; 7–9 -veined. Lower glume lateral veins unequally thickened; ribbed. Lower glume surface pubescent. Lower glume apex awned; 2–3 -awned. Lower glume awn 20–50 mm long. Upper glume elliptic; gibbous; 9–10 mm long; 0.9 length of adjacent fertile lemma; coriaceous; without keels; 7–9 -veined. Upper glume lateral veins unequally thickened; ribbed; parallel at apex. Upper glume surface pubescent. Upper glume awned; 2–3 -awned. Upper glume awn 20–50 mm long.
FLORETS Fertile lemma oblong; 10–11 mm long; coriaceous; without keel; 5 -veined. Lemma apex dentate; 2–4 -fid; awned; 2–4 -awned. Principal lemma awn 10–25 mm long overall. Palea 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Lodicules 2. Ovary pubescent on apex.
FRUIT Caryopsis with adherent pericarp; hairy at apex. Disseminule comprising a inflorescence.
DISTRIBUTION Europe: southwestern, southeastern, and eastern. Africa: north. Asia-temperate: Soviet Middle Asia, Caucasus, and western Asia.
