covered with long white hairs which are longer and more 1 numerous 

 toward the apex. The apex of the hull terminates in four conical 

 pale-yellow teeth. The two prominent ones are located on the meson, 

 are unequal in length, and are slightly bent ventrad. The other two 

 are lateral and very short. 



The kernels (PI. IV, G and //) average in length 6.6 millimeters, 

 in width 1.9 millimeters, and in thickness 2.8 millimeters. Viewed 

 laterally, the dorsal and ventral margins are equally convex, and the 

 distal end is obtuse. The opaque area when present is small and 

 located on or near the dorsal margin. 



This variety matures in approximately 1-18 days and has produced 

 an average acre yield of 2.08G pounds of paddy and 2.520 pounds of 

 straw. Although it has the longest growing period of any of the 

 varieties cultivated in this country. Blue Rose is preferred in the 

 Southern States to the more productive Japanese varieties because 

 of the general similarity of its kernels to those of the Honduras 

 variety, which is so widely known and valued as a rice of excellent 

 cooking quality. It lacks, however, the culinary properties of Hon- 

 duras rice, but it produces a larger yield of head rice, upon which, 

 unfortunately, the miller has placed too high a premium. Large 

 mill yields are important, and varieties that can produce them are 

 desirable, but a rice must also possess certain qualities for table use 

 before it can become a highly marketable product for the occasional 

 as well as the daily consumer. 



SHINRIKI. 



The principal introduction of the Shinriki variety was made from 

 da pan in 1902 by Dr. S. A. Knapp, then an agricultural explorer of 

 the United States Department of Agriculture. Prior to 1910 Shin- 

 riki was probably the best known of the Japanese varieties grown in 

 Louisiana and Texas. 



The slender wiry culms of this variety are light green and usually 

 number 13 to the plant. Their average height, including the panicles, 

 is 37 inches. The culm and sheath nodes are light green. The 

 auricles are deciduous. The ligules are half an inch long. The leaf 

 blades are very narrow, averaging three-eighths of an inch in width. 

 The panicles have an average length of 8 inches, and each bears on 

 an average 105 seeds. 



The seeds (PI. IV, / and J) average 7.3 millimeters in length and 

 3.6 millimeters in thickness. The glumes are pale yellow and have 

 smooth margins. The hull, which loosely incloses the kernel, is light 

 yellow and medium in thickness. Its surface has a burlaplike ap- 

 pearance and is thinly covered with short white hairs, which are 

 longer and more conspicuous toward the apex. The apex of the hull 

 terminates in four conical light-green teeth. The two prominent 

 ones are located on the meson and are unequal in length. The other 

 two are lateral and very short. 



The kernels (PI. IV, K and L) average in length 5.4 millimeters, 

 in width 2.1 millimeters, and in thickness 3.1 millimeters. Viewed 

 laterally, the dorsal and ventral margins are equally convex, and the 

 distal end is broadly obtuse. The opaque area is seldom conspicu- 

 ous and when present is located on the dorsal margin.
