culture, rather than to any original differences. The plant is described by botanists, as a strong, reedy, jointed stalk, provided with large alternate leaves, almost like flags, springing from every joint. The top produces a bunch of male flowers, of various colours, which is called the tassel. Each plant bears, likewise, one or more spikes or ears, seldom so few as one, and rarely more than four or five, the most usual number being three; as many as seven have been seen occasionally on one stalk. These ears proceed from the stalk at various distances from the ground, and are closely enveloped by several thin leaves, forming a sheath, which is called the husk. The ears consist of a cylindrical substance, of the nature of a pith, which is called the cob, over the entire surface of which the seeds are ranged, and fixed in eight or more straight rows, each row having generally as many as thirty or more seeds. The eyes, or germs of the seeds, are in nearly radial lines from the centre of the cylinder; from these eyes proceed individual filaments of a silky appearance, and of a bright-green colour; the aggregate of these hang out from the point of the husk, in a thick cluster, and in this state are called the silk. It is the office of these filaments, which are the stigmata, to receive the farina, which drops from the flowers on the top or tassel, and without which the ears would produce no seed,—a fact which has been established by cutting off the top previous to the development of its flowers, when the ears proved wholly barren. So soon as their office has been thus performed, both the tassel and the silk dry up, and put on a withered appearance.
The grains of maize are of different colours, the prevailing hue being yellow of various shades, sometimes approaching to white, and at other times deepening to red. Some are of a deep chocolate-colour, others greenish or olive-coloured, and even the same ears will sometimes contain grains of different colours.
