The word maize derives from the Spanish form of the indigenous Taíno word for the plant, maiz. It is known by other names around the world.
Corn outside North America, Australia, and New Zealand means any cereal crop, its meaning understood to vary geographically to refer to the local staple.In the United StatesCanada Australia, and New Zealand,[citation needed] corn primarily means maize; this usage started as a shortening of "Indian corn". "Indian corn" primarily means maize (the staple grain of indigenous Americans), but can refer more specifically to multicolored "flint corn" used for decoration.In places outside North America, Australia, and New Zealand, corn often refers to maize in culinary contexts. The narrower meaning is usually indicated by some additional word, as in sweet corn, corn on the cob, popcorn, corn flakes, baby corn.Maize is preferred in formal, scientific, and international usage because it refers specifically to this one grain, unlike corn, which has a complex variety of meanings that vary by context and geographic region.Maize is used by agricultural bodies and research institutes such as the FAO and CSIRO. National agricultural and industry associations often include the word maize in their name even in English-speaking countries where the local, informal word is something other than maize; for example, the Maize Association of Australia, the Indian Maize Development Association, the Kenya Maize Consortium and Maize Breeders Network, the National Maize Association of Nigeria, the Zimbabwe Seed Maize Association. However, in commodities trading, corn consistently refers to maize and not other grains
The maize plant is often 2.5 m (meters) (8 ft) in height, though some natural strains can grow 12 m (40 ft). The stem has the appearance of a bamboo cane and is commonly composed of 20 internodes of 18 cm (7 in) length. A leaf grows from each node, which is generally 9 cm (3.5 in) in width and 120 cm (4 ft) in length.Ears develop above
