Lettuce (Lactuca sativa). The garden lettuce is supposed to be a native of the East Indies, but is not known to exist anywhere in a wild state, and from remote antiquity has been cultivated as an esculent and particularly as a salad. It has a leafy stem, oblong leaves, a spreading, flat-topped panicle, with yellow flowers, and a fruit without margin. It is now generally cultivated in all parts of the world where the climate admits of it.
Melon (Cucumis melo), a plant of the same genus with the cucumber, much cultivated for its fruit. The melon is an annual, with trailing or climbing stems, lateral tendrils, rounded, angular leaves, small, yellow flowers and large round or somewhat ovate fruit. The varieties in cultivation are very numerous, some of them distinguished by a thick and warty rind, some by a rind cracked in a net-like manner, some by ribs and furrows, some by a perfectly smooth and thin rind; they differ also in the color of the flesh of the fruit, which is green, red, yellow, etc.; and in the size of the fruit, which varies from three or four inches to a foot or more in diameter. They are widely cultivated in the United States, ranking fifth in acreage among vegetables. New Jersey leads in production, growing about one-seventh of entire crop. Cultivation under irrigation is highly developed in Colorado. They are often called cantaloupe in the markets.

Okra or Gumbo (Hibiscus esculentus) is a generally used food plant most commonly employed in soups in the East and West Indies and also in the southern United States. It was anciently grown in tropical Africa and Egypt, and is now [131] diffused in tropical countries and in the southern United States.
Onion (Allium Cepa) is extensively cultivated throughout the world, and is grown in every state in the United States, New York and Ohio leading in production. Bermuda and Spanish varieties are now grown in California. It was cultivated by the ancient Egyptians; also by the Greeks and Romans. Many other important vegetables are allied to the onion, viz.: Leek, Shallot, Onion, Chives and Garlic. All of these are highly esteemed in cookery.
Parsnip (Pastinaca), an annual, biennial, or perennial herb, with carrot-like, often fleshy root and pinnate leaves. The parsnip has long been cultivated for the sake of its root, which in cultivation has greatly increased in size and become more fleshy. The flavor is disliked by some, as well as the too great sweetness, but highly relished by others; and the root of the parsnip is more nutritious than that of the carrot. The crop is also on many soils of larger quantity; and although the parsnip delights in a very open, rich soil, it will succeed in clayey soils far too stiff for the carrot.
Pea (Pisum sativum) has been cultivated from very remote times. The pea plant is covered with a delicate, glaucous bloom, and its white or pale violet flowers are familiar to all. The pods are pendulous, smooth, deep green and variable in size and may contain any number up to thirteen (rarely more) peas. The peas when ripe are also variable, some being white and round, others blue and wrinkled, and a few large, irregular, and dull green. They are cultivated in Europe, Asia and the United States. Chiefly used as green vegetable, but also for fodder. Ranks seventh in acreage among minor vegetables in the United States.
Peppers or Capsicums or Chillies (Capsicum annum and C. frutescens) are widely cultivated in the warmer parts of both hemispheres. The fruits vary considerably in shape and size, and when green are cooked and eaten as a vegetable.
Potato (Solanum tuberosum) is the greatest of vegetable gifts to man. Its cabbage-like stalks have a height of from eighteen to twenty inches; its leaves are solitary and pennate; its large pentagonal blossoms are white, reddish or violet; its fruit is a green berry. Attached to its underground runners are those bulbs which serve as food to many millions of people, and from which starch, sago, sugar of grapes and brandy are prepared.
The potato stands second only to corn as the most important contribution of America to the food plants of the world. Preëminently the most important vegetable grown in Europe and America. The world crop is enormous, exceeding five billion bushels; in bulk surpassing by about one-half the world crop of wheat, corn or oats. Germany, Russia, Austria-Hungary, France, the United States and Great Britain are the chief producers in order named. Germany grows one-third of the world crop, Russia one-fifth. In the United States they are grown in every state and territory; also in Hawaii and Alaska.
