Common name: Common Wheat, Bread Wheat
Triticum aestivum L. APNI*
Description: Robust annual to c. 1 m high.
Leaves with ligule membranous, 0.5–2 mm long, obtuse, erose; auricles membranous, hairy or glabrous; blade flat, to 2 cm wide.
Inflorescence 5–15 cm long (excluding awns), to 2 cm wide (excluding awns); rachis flattened, flexuous, sometimes velvety with hairs to 0.1 mm long, edges pubescent with hairs to 1.5 mm long (longest toward the nodes). Spikelets 12–17 mm long (excluding awns); florets 3–6, upper 1 or 2 florets often sterile. Glumes 10–12 mm long, apex truncate and/or toothed, upper 25% silky with hairs to 0.5 mm long, rigid; awn terminal, antrorsely barbed, straight, to 7.5 mm long. Lemmas 10–13 mm long, truncate and/or toothed and/or awned, 7-nerved, upper 25% silky with hairs to 0.5 mm long. Palea c. 12 mm long.
Distribution and occurrence: Common along roadsides in wheat-growing areas. Native of Medit. region.

T. durum Desf. resembles T. aestivum, but, the spike rachis of the former is usually hairy at the nodes, and glumes have a crested keel throughout their length. Because breeding and selection of cultivars has been so intensive there is considerable morphological variation in Triticum aestivum. X Triticale is a hybrid between wheat and rye is now grown as a cereal and forage crop, and is commonly planted to stabilize roadsides in N.S.W.
