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.
