Taxonomic Comments

Cultivated corn is treated by Kartesz (Synthesis of the North American Flora, 1999) as Zea mays ssp. mays, in contrast to Z. mays ssp. parviglumis, one of the species of teosinte. (Another teosinte is Z. mexicana, sometimes treated as Z. mays ssp. mexicana.). However, in many floristic and agricultural works, corn/maize is treated as a distinct species, Zea mays, separate from the teosintes.
