Einkorn wheat (from German Einkorn, literally "single grain") can refer either to the wild species of wheat, Triticum boeoticum, or to the domesticated form, Triticum monococcum. The wild and domesticated forms are either considered separate species, as here, or as subspecies: Triticum monococcum subsp. boeoticum (wild) and T. monococcum subsp. monococcum (domesticated). Einkorn is a diploid species (2n = 14 chromosomes) of hulled wheat, with tough glumes ('husks') that tightly enclose the grains. The cultivated form is similar to the wild, except that the ear stays intact when ripe and the seeds are larger. The domestic form is known as petit épeautre in French, Einkorn in German, einkorn or littlespelt in English, piccolo farro in Italian and espelta petita in Catalan.
