any one plant species of the genus Euchlaena of the family Gramineae. The most common species is E. mexicana, an annual reaching 3 m tall and resembling maize. The staminate spikelets are gathered into terminal panicles; the pistillate spike-lets are in small distichous ears located in the leaf axils. The fruit is a caryopsis. E. mexicana is found in Mexico, where it grows as a weed in corn plantings. Teosintes are cultivated in southern North America and various other regions for hay, as green feed, and sometimes as cereal plants.
