Maize or Indian Corn or Sweetcorn (Zea mays) is a true grass and is only known in the cultivated state. It is indigenous in tropical America and has been cultivated for ages in Asiatic islands under the equator, from whence it passed northward to China and westward toward to India and Turkey. It is monoecious, producing beautifully tasselled male flowers; and the female flowers, which develop the 'cobs' are found closely applied to the central axils of the leaves below. Research Maize
