6 OUR FARM CROPS. 



the correct nomenclature of the endless (so-called) varieties, 1 

 which enter into our ordinary cultivation. By common 

 consent, M. Louis Vilmorin, in France, and Mr. Lawson, 

 in this country, are looked upon as the best authorities 

 on the subject. Therefore we cannot do better than follow 

 the division and classification of the genus, so ably drawn 

 up by the former, while the descriptions and agricultural 

 characteristics of the cultivated varieties, by Mr. Lawson, 

 will enable us to form correct opinions of their nature 

 and suitability to our several requirements. 



M. Vilmorin divides the genus "Wheat" under seven 

 heads or "species:" 



1. TRITICUM SATIVUM Common Wheat. 



2. TRITICUM TURGIDUM Turgid Wheat. 



3. TRITICUM DURUM Hard Wheat. 



4. TRITICUM POLONICUM Polish Wheat. 



5. TRITICUM AMTLEUM Starch Wheat. 



6. TRITICUM MONOCOCCUM One-grain W T heat. 



7. TRITICUM SPELT A Spelt. 



The four first species have their seed or grain naked, 

 while the seed of the remaining species has the chaff-scales 

 adhering to it. 



No. 1, T. sativum, is arranged in two principal divi- 

 sions, " bearded," and " smooth or beardless." Of the 

 bearded there appear to be seven, and of the smooth or 

 beardless twenty-seven distinct varieties; and these are 

 again divided into sub -varieties according to their colour, 

 as white, yellow, or red, and according also as the chaff- 

 scales are smooth or rough. 



No. 2, T. turgidum, has two principal divisions those 

 varieties having simple ears, and those having compound 

 the sub- varieties being determined by the colour, white, 

 red, or dark, and by the rough or smooth character of the

 of Trade at the Paris Exhibition, no less than 128 different varieties (?) were 

 shown.
