Triticum turgidum
HABIT Annual; caespitose. Culms 90–160 cm long. Culm-internodes with small lumen, or solid. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs ciliate. Leaf-sheath auricles falcate. Ligule an eciliate membrane. Leaf-blades 10–60 cm long; 10–15 mm wide; glaucous. Leaf-blade surface pubescent.
INFLORESCENCE Inflorescence composed of racemes.
Racemes 1; single; oblong, or ovate; arcuate; bilateral; 7–10 cm long; simple, or secondarily branched. Rhachis tough; flattened; puberulous on surface (as an apical tuft); ciliate on margins. Spikelet packing broadside to rhachis. Rhachis internodes oblong; 3.5–4 mm long.
Spikelets ascending; solitary. Fertile spikelets sessile.
FERTILE SPIKELETS Spikelets comprising 3–5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 10–13 mm long; 8–15 mm wide; persistent on plant.
GLUMES Glumes similar; shorter than spikelet. Lower glume ovate; 8–11 mm long; 1 length of upper glume; coriaceous; 2-keeled; keeled all along; 5–9 -veined. Lower glume surface glabrous, or pubescent. Lower glume apex with a unilateral tooth; truncate. Upper glume ovate; 8–11 mm long; 0.6–0.7 length of adjacent fertile lemma; coriaceous; 2-keeled; keeled all along; 5–9 -veined. Upper glume lateral veins divergent at apex. Upper glume surface glabrous, or pubescent. Upper glume apex with a unilateral tooth; truncate.
FLORETS Fertile lemma elliptic; 10–13 mm long; coriaceous; without keel; 5–9 -veined. Lemma apex acute; awned; 1 -awned. Principal lemma awn 80–160 mm long overall; limb scabrous. Palea 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Anthers 3. Ovary with a fleshy appendage below style insertion; pubescent on apex.
FRUIT Caryopsis with adherent pericarp; 8 mm long; hairy at apex. Hilum linear.
DISTRIBUTION Europe: southwestern, southeastern, and eastern. Africa: north and northeast tropical. Asia-temperate: Siberia, Caucasus, western Asia, and China. Asia-tropical: India.
