See also:MAIZE, or See also:INDIAN See also:CORN , Zea Mays (from i-See also:ea or which appears to have been " spelt," Triticum spelta, according to the description of See also:Theophrastus), a plant of the tribe Maydeae of the See also:order Gramineae or See also:grasses (see fig . 1) . It is unknown in the native See also:state, but is most probably indigenous to tropical See also:America . Small grains of an unknown variety have been found in the See also:ancient tombs of See also:Peru, and See also:Darwin found heads of See also:maize embedded on the See also:shore in Peru at 85 ft. above the See also:present See also:sea-level . Bonafous, however (Histoire naturelle du mais), quotes authorities (Bock, 1532, Ruel and See also:Fuchs) as believing that it came from See also:Asia, and maize was said by See also:Santa See also:Rosa de See also:Viterbo to have been brought by the See also:Arabs into See also:Spain in the 13th See also:century . A See also:drawing of maize is also given by Bonafous from a See also:Chinese See also:work on natural See also:history, Li-chi-ichin, dated 1562, a little over sixty years after the See also:discovery of the New See also:World . It is not figured on See also:Egyptian monuments, nor was any I. any mention made of it by Maize—Zea Mays—unripe See also:cob . Eastern travellers in See also:Africa or The membranous spathes have Asia See also:prior to the 16th cen- been cut and See also:drawn aside, revealing tury . See also:Humboldt, See also:Alphonse de the spike of See also:fruit which bears the See also:Candolle and others, however, See also:long silky styles . One-third nat. do not hesitate to say that it See also:size. originated solely in America, where it had been long and extensively cultivated at the See also:period of the discovery of the New World; and that is the generally accepted See also:modern view . Some hold the view that maize originated from a See also:common Mexican See also:fodder grass, Euchlaena mexicana, known as Teosinte, a closely allied plant which when crossed with maize yields a maize-like hybrid . The plant is monoecious, producing the staminate (male) See also:flowers in a large feathery panicle at the See also:summit, and the (See also:female) dense spikes of flowers, or cobs," in the axils of the leaves below, the long See also:pink styles See also:hanging out like a silken tassel . They are invested by the sheaths of leaves, much used in packing oranges in See also:south See also:Europe, and the more delicate ones for cigarettes in South America . Fig . 2 shows a See also:branch of the terminal male inflorescence . Fig . 3 is a single spikelet of the same, containing two florets, with the three stamens of one only protruded . Fig . 4 is a spike of the female inflorescence, protected by the sheaths of leaves—the See also:blades being also present . Usually the sheaths terminate in a point, the blades being arrested . Fig . 5 is a spikelet of the female inflorescence, consisting of two See also:outer glumes, the See also:lower one ciliated, which enclose two florets—one (a) barren (sometimes fertile), consisting of a flowering glume and See also:pale only, and the other (b) fertile, containing the See also:pistil with elongated See also:style . The See also:mass of styles from the whole spike is pendulous from the summit of the sheaths, as in fig . 4 .

More than three See also:hundred varieties are known, which differ more among themselves than those of any other cereal
.
Some come to maturity in two months, others require seven months; some are as many feet high as others are inches; some havekernels eleven times larger than others
.
They vary similarly in shape and size of ears, See also:colour of the grain, which may be See also:

Dent or See also: United States . In starchy sweet corn (var. amylea-saccharata) the grain has the See also:external appearance of sweet corn, but examination shows the lower See also:half to be starchy, the upper horny and translucent . A form of flint corn, with variegated leaves, is grown for ornament under the name Zea japonica or See also:Japanese striped corn . Chemical See also:analysis, like common experience, shows that See also:Indian corn is a very nutritious article of See also:food, being richer in albuminoids than any other cereals when ripe (calculated in the dry See also:weight) . It can be grown in the tropics from the level of the sea to a height equal to that of the See also:Pyrenees and in the south and See also:middle of Europe, but it cannot be grown in See also:England with any See also:chance of profit, except perhaps as fodder . See also:Frost kills the plant in all its stages and all its varieties; and the See also:crop does not flourish well if the nights are cool, no matter how favourable the other conditions . Consequently it is the first crop to disappear as one ascends into the See also:mountain regions, and comparatively little is grown See also:west of the See also:great plains of North America . In See also:Brittany, where it scarcely ripens the grain, it furnishes a strong crop in the autumn upon sandy See also:soil where See also:clover and See also:lucerne will yield but a 'poor produce . It prefers a deep, See also:rich, warm, dry and mellow soil, and hence the rich bottoms and fertile prairies of the See also:Mississippi See also:basin constitute the region of its greatest See also:production . It is extensively grown throughout See also:India, both for the ripe grain and for use of the unripe cob as a See also:green vegetable . It is the most common crop throughout South Africa, where it is known as mealies, being the See also:staple food of the natives . It is also largely used for fodder and is an important article of export . As an article of food maize is one of the most extensively used grains in the world . Although rich in nitrogenous matter and See also:fat, it does not make See also:good See also:bread . A mixture of See also:rye and corn See also:meal, however, makes an excellent coarse bread, formerly much used iii the See also:Atlantic states, and a similar bread is now the See also:chief coarse bread of See also:Portugal and some, parts of Spain . It is either baked into cakes, called tortilla by the Indians of See also:Yucatan, or made into a See also:kind of See also:porridge, as in See also:Ireland . When deprived of the See also:gluten it constitutes See also:oswego, maizena or corn See also:flour . Maize contains more oil than any other cereal, ranging from 3.5 to 9.5% in the commercial grain . This is one of the factors in its value for fattening purposes . In distilling and some other processes this oil is separated and forms an article of commerce . When maize is sown. broadcast or closely planted in drills the ears may not develop at all, but the stalk is richer in See also:sugar and sweeter; and this is the basis of growing " corn-fodder." The amount of See also:forage that may be produced in this way is enormous; 50,000 to 8o,000 lb of green fodder are grown per See also:acre, which makes 8000 to 12,000 lb as field-cured . Sugar and See also:molasses have from See also:time to time been manufactured from the corn stalks . See articles on corn and Zea Mays in L . H .
