APPENDIX

CLASSIFICATION OF WHEAT

Following the classifications of Carleton,1 of Haeckel,' and of Kornicke and Werner, and perfecting them by adding new data, by extending to smaller subdivisions, by giving world distribution, and, for the sake of unity and completeness, by giving the essential characteristics of each division, there is given below a descriptive and distributive outline of the division Hordes given on Page 2.

1.1 Hordese (Sub-tribe).

2 1 Lolice (Rye Grass). 3 I Lepturefc.

4 I Elymea: (Barley Wild Rye).
S.l Triticeal

1.2 Agropvrum (Genus) (Quack. G
2.2 Haynaldia.
3.2 Secale (Rye).
4.2 Triticum.

1.3 Aegilops (section). Species ovata taken as type. Found in southern Europe to Turkestan in Asia. Twelve species in all arc recognized. 2.3 Sitopyrus.

1.4 Triticum monococcum.

1.5 Name: None in English. German Einkorn preferred. French Engrain. 2.5 Characteristics: Spikelets three flowered but one grained; hardy; non-shattering; short, thin narrow-leaved plant, seldom over 3 feet high. Very constant in fertility; does not give fertile cross with common wheat; only species in which pale* fall in two parts at maturity; spikelets awned; spike compact.

3.S Distribution: Found from Achaia in Greece to Mesopotamia. Present in Swiss Lake dwellings of stone age. Cultivated to a limited extent in Spain, France, Germany Switzerland and Italy. Unknown in America except to experimenters. 4.5 Varieties: Einkorn', Engrain double (two grains). 5.5 Use: Rarely for bread; usually for mush and "cracked wheat," and for fodder. 2.4 Triticum Polonicum.

1.5 Name: Polish wheat a misnomer; Giant or Jerusalem rye. Perhaps native in Mediterranean region. 2.5 Characteristics: Only species in which lowest flower has palea as long as its glume; outer glumes at least as long as flowering glumes; two to three seeded; tall; stems pithy within; heads and kernelsextremely large; macaroni gluten; drought and rust resistant; resembles rye. 3.5 Distribution: Spain; Italy; Abyssinia; Southern Russia and Turkestan: Brazil; Northwestern United States. 4.5 Varieties: Only one. White Polish, is widely known. 5.5 Use: Principally for macaroni. 3.4 Triticum sativum dicoccum.

1 5 Name: None in English, often erroneously called spelt; German emmer preferred.

i U. 8. Drpt Agr., Div. Veg. Phy«. and Path., Bui. 24, p. 6. « Minn. Bui 62, p. 392.

2.5 Characteristics: Probably derived from Einkorn; leaves usuallv velvety hairy; plants pithy or hollow; heads very compact and flat almost always bearded; threshing does not remove chaff; spikelets two-grained; non-shattering; some varieties drought and rust resistant. 3.5 Distribution: Extensively in Russia and Servia; Germany; Spain; Abyssinia; Switzerland; to some extent in France, and Italy; also perhaps in northern India Thibet, and in portions of China; in the United States; cultivated in prehistoric times. 4.5 Varieties: Red chaff; white chaff; etc.

1.5 Name: English, spelt; German, spels or dinkel; French cpeautre.

2.5 Characteristics: Grows fully as tall as wheat; heads loose, narrow, rather long, bearded or bald; very brittle rachis; spikelets two to five-grained; far apart in head; hardy; non-shattering; constancy in fertility; retains chaff in threshing.

3.5 Distribution: The oldest grain cultivated in ancient Egypt, Greece and the Roman Empire. With emmer is the principal bread grain of southwest German Empire; raised widely in Russia, Switzerland. Belgium, France, Italy, Spain. In Canada and the United States it is known only to experimenters.

4.5 Varieties: Winter and spring varieties white-bearded; black-bearded; red; smooth; white.

5.5 Use: Flour is placed in same rank as common wheat flour; fed to stock. 5.4 Triticum sat. compactum.

1.5 Name: Club or square head wheats; also "hedgehog wheat." "dwarf wheat."

2.5 Characteristics: Little more than two feet high, being a dwarf; heads very short, often squarely formed; commonly white, at times red; bearded or bald; spikclts very close, three or four-grained; grain short and small, red or white; great yielding power; stiff straw; non-shattering; eary maturity; drought resistant.

3.5 Distribution: Pacific coast and Rocky Mountain states of the United States; Chile; Turkestan; Abyssinia; to slight extent in Switzerland, Russia, and a few other districts of Europe.

4.5 Varieties: Generally known as "club" or "square head"; dwarf; hedgehog.

5.5 Use: Yield the flour desired in certain localities; crackers; breakfast foods. 6.4 Triticum sat. turgidum.

1.5 Name: Poulard or pollard wheats; English (a misnomer), rivet; German, bauchiger Wctccn; French, ble pctanicllc; also known as English wheat; Egyptian wheat. 2.5 Characteristics: Rather tall; broad velvety leaves; stems thick and stiff; heads long, often square; bearded; spikelets compact, two to four-grained; grains hard and light color; resistant to rust and drought.

3.5 Distribution: France, Egypt, Italy, Turkey, Greece, Southern Russia, other Mediterranean and Black Sea districts, and experimentally in the United States.

4.5 Varieties: Poulard; composite wheats (T. compositum), known as Miracle, Egyptian or Mummy wheats, having branched or compound heads whose grains develop unequally.

5.5 Use: Macaroni and other pastes; bread; mixed with bread wheats to produce flour desired by certain French markets. 7.4 Triticum sat. durum.

1.5 Name: Durum, macaroni, or flint wheats.

2.5 Characteristics: Hardest grain and longest beard known among wheats; plants tall; leaves smooth with hard cuticle; heads slender, compact, at times very short; always bearded; grains glassy, sometimes rather transparent, yellowish, long; very sensitive to changes of environment; high gluten content; drought and rust resistant; spikelets two to four-grained.

3.5 Distribution: Practically the only wheat of Algeria, Spain, Greece, Mexico, and Central America; extensively raised in south and east Russia, Asia Minor, Turkestan, Egypt, Tunis, Sicily, Italy, India, Chile, Argentina, United States, and Canada. 4.5 Varieties:

1.6 Gharnovka, Velvet Don, and Arnautka (Azov Sea region, Russia) United States. 2.6 Kubanka (east of Volga river, Russia), United States. 3.6 Saragolla (southeast Italy). 4.6 Goose wheat (Canada. Dakota). 5.6 Trigo candeal and Anchuelo (Argentina). 6.6 Nicaragua (Central America, Texas). 7.6 There are perhaps several dozen other varieties. 5.5 Uses: Macaroni; semolina; noodles; all kinds of pastries; bread; it is coming to be used for all purposes, in some regions, as ordinary wheat flour. 3.4 Triticum vulgare.

1.5 Name: This is the common bread wheat.

2.5 Characteristics: Well known; heads rather loosely formed; bearded or bald; chaff usually smooth but may be velvety; spikelets generally three-grained, but may be two, and rarely four; stem usually hollow; all the characteristics vary widely (see varieties). 3.5 Distribution: Practically over the whole globe, within the limits

already given (see varieties). 4.5 Varieties: (Carleton's division, based not on botanical but on environmental characteristics). 1.6 Soft winter wheats: Grain amber to white; produced by moist mild climate of even temperature; found in eastern United States, western and northern Europe, Japan, and in portions of China India, Australia, and Argentina. 2.6 Hard winter wheats: Usually red-grained; usually bearded; relatively high gluten content; grown on black soils in climate characterized by extremes of temperature and moisture. Found chiefly in Kansas, Nebraska, Iowa, Missouri, and Oklahoma in the United States (the wheat of Crimean origin known as "Turkey red"), in Argentina (the Italian wheat, Barletta), in Hungary and Roumania, in southern and southwestern Russia, and to some extent in Canada, northern India, Asiatic Turkey, and Persia. 3.6 Hard spring wheats: What has been said of the hard winter wheats also applies to this group, the difference being that the growing season is shorter, and the winter too severe for winter varieties. They are found in central and western Canada, the north central states of the United States (these are the fife and blue-stem wheats), east Russia and western and southern Siberia. 4.6 White wheats: Soft and very starchy; grains harder and much drier than those of the soft winter wheats; fall or spring sown, even in same locality; grown chiefly in the Pacific coast and Rocky Mountain states of the United States, in Australia, in Chile, in Turkestan, and the Caucasus. 5.6 Early wheats: Grain soft or semi-hard, amber to red; main characteristic is that they ripen early. Found in Australia and India, have a slight representation in California, and include some of the dwarf wheats of Japan. 5.5 Districts in the United States (Carleton'sdivision). 1.6 Soft wheat.
