Morphology General Habit
Annual up to 100 cm high; leaves flat
Morphology Reproductive morphology Inflorescences
Panicle contracted and narrowly elliptic to diffuse and ovate, 10–60 cm long, the branches ascending, flexuous, the lowermost often whorled
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets narrowly oblong, 4–9 mm long, 4- to 12-flowered, the florets remaining intact on the tough rhachilla and retaining the plump grain, occasionally some lemmas and paleas eventually falling; glumes unequal, lanceolate, acuminate, the lower 1–2.8 mm long, the upper 1.5–3 mm long; lemmas oblong-lanceolate in profile, membranous, 2–3 mm long, scaberulous on the keel and on the flanks above, acute; palea-keels scaberulous; anthers 3, (0.2–)0.3–0.5 mm long
Morphology Reproductive morphology Fruits
Grain turgid, 1–2 mm long.
Distribution
?N1 introduced or adventive elsewhere.
Note
As a cereal, E. tef is apparently not cultivated outside Ethiopia. The single known occurrence of the species in northern Somalia is from 1931. There are no modern records.
