Spikelets 25^10 mm, with 4-5 florets, 2-3 seed-forming. Glumes 20-40 mm, often concealing the florets, lanceolate, chartaceous, loosely appressed to the lower florets, with 1 prominent keel, apices acute, terminating in a tooth; lemmas to 30 mm, chartaceous, toothed or awned, awns on the lower 2 lemmas to 15 cm; paleas not splitting at maturity.

Discussion
Triticum polonicum is a minor, durum-like, spring wheat species. It is grown in the Mediterranean basin and central Asia on a small scale. In the Flora region, it is grown principally for plant breeding. It differs from other domesticated wheats in its unusually long, chartaceous glumes and lemmas. The epithet "polo¬nicum" reflects an early European botanical bias; the species did not originate in Poland.
