4275. Triticoi vulgare. Wheat. 



From California. Received February 7, 1900. 



Sonora. A winter wheat in mild climates. It has a reddish velvet chaff, without 

 beards, and a white or reddish-white grain. It is rather productive and somewhat 

 drought-resistant. It is adapted for the Pacific coast States and for growth under 

 irrigation. 



4276. Triticum vulgare. Wheat. 



From Washington. Received from Mr. L. F. Hammersmith, Lincoln County, 

 Wash., January, 1900. 



Lamona. Mr. Hammersmith describes this variety of wheat as follows: " It is 

 the best drought-resistant wheat ever tried here, yielding from 20 to 30 bushels per 

 acre of fine, plump kernels. It is a No. 1 milling wheat and sells for the highest 

 price in our markets. This wheat was sown late last spring (1898) on a field where 

 winter wheat had failed through being frozen out. It was planted almost too late 

 for blue stem even." For trial in Kansas, Nebraska, Colorado, and Wyoming. Dis- 

 tributed. 



4277. Tritictjm durum. Wheat. 



From Texas. Received January 10, 1900. 



Nicaragua. This variety is one of the macaroni wheats and has been grown on the 

 Southwestern plains of the United States for a number of years. It is the only durum 

 wheat that has yet gained any very great popularity in the country. But from the 

 cultural standpoint it is so successful that only its general employment in macaroni 

 making is needed to make it one of the most important of our wheat varieties. It is 

 at present grown chiefly in Texas, but its area of cultivation needs to be much more 

 widely extended. It is adapted for growing in a hot climate, and, though it requires 

 considerable moisture at certain periods, it will mature a good crop with a less rainfall 

 than is required by other varieties. It yields 30 to 40 bushels per acre in the black, 

 waxy soils of central Texas, but will probably produce a grain of a little better quality 

 farther westward, near the one hundredth meridian, where the soils are a little grayer 

 and the climate drier. It is most successfully grown as a winter variety, at least as 

 far north as the thirty-third parallel, and should be sown about November 1 to 

 November 15 south of latitude 30° and about October 15 to November 1 between that 

 parallel and latitude 33°. In Oklahoma and other districts farther north it will 

 probably not survive the winter, but must be grown as a spring variety, and, if so, 

 should be sown from February 1 to February 15, or as early as the opening of spring 

 will allow. It should not be very thickly sown and should always be sown with a
