Aegilops vavilovii
Zarif buğday
Annual; caespitose. Culms erect, or geniculately ascending; robust; 30–75 cm long. Leaf-sheath oral hairs lacking. Leaf-sheath auricles falcate. Ligule an eciliate membrane. Leaf-blades 10–20 cm long; 4–10 mm wide. Leaf-blade surface glabrous. Inflorescence composed of racemes; not deciduous as a whole. Racemes 1; single; moniliform; smoothly terete; bilateral; 10–15 cm long; bearing 7–10 fertile spikelets on each. Rhachis fragile at the nodes; semiterete. Spikelet packing broadside to rhachis. Rhachis internodes oblong; falling with spikelet alongside. Sterile spikelets appressed; solitary. Fertile spikelets sessile. Basal sterile spikelets absent, or rudimentary; 0–2 in number. Fertile spikelets comprising 2–3 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 8–15 mm long; falling entire; deciduous with accessory branch structures.Glumes similar; shorter than spikelet. Lower glume ovate; asymmetrical; 7–10 mm long; 1 length of upper glume; coriaceous; without keels; 7–10 -veined. Lower glume lateral veins unequally thickened; ribbed; parallel at apex. Lower glume surface pubescent. Lower glume apex dentate; 2–3 -fid; truncate; awned, or awned only on distal spikelets; 1 -awned. Lower glume awn terminal ; 10–25 mm long. Upper glume ovate; asymmetrical; 7–10 mm long; 0.9 length of adjacent fertile lemma; coriaceous; without keels; 7–10 -veined. Upper glume lateral veins unequally thickened; ribbed; parallel at apex. Upper glume surface pubescent. Upper glume apex dentate; 2–3 -fid; truncate; awned, or awned only on distal spikelets; 1 -awned. Upper glume awn terminal ; 10–25 mm long. Fertile lemma ovate; 8–11 mm long; coriaceous; keeled; 5 -veined. Lemma surface pubescent. Lemma apex dentate; 3 -fid; with outer lobes shorter; truncate; awned; 1 -awned, or 2 -awned. Principal lemma awn flat below; 50–80 mm long overall. Lateral lemma awns arising on apex of lobes. Palea 2 -veined. Apical sterile florets resembling fertile though underdeveloped. Lodicules 2. Ovary with a fleshy appendage below style insertion; pubescent on apex. Caryopsis with adherent pericarp; hairy at apex. Disseminule comprising a rhachis internode.
Asia-temperate: western Asia and Arabia.
