Maize (Zea mays)

Maize (Zea mays). The flowers are unisexual, containing either stamens or ovary but not both. The long, crowded inflorescences bear flowers of only one sex. The male inflorescences are on terminal branches and the female inflorescences are lower down, on lateral branches. The male flowers are small, and enclosed by green, leaf-like bracts. The flowers are in pairs; each pair is called a spikelet which is enclosed by two bracts. Two smaller bracts enclose three stamens. When mature, the anthers hang outside the bracts.
