60 THE SOY BEAN ; HISTORY, VARIETIES, AND FIELD STUDIES. 



22380. From Canton, Kwangtung, China, 1908. Plants slender, erect, the tips 



twining; height 30 to 36 inches; late; pubescence tawny; flowers white; 

 pods large, 2 to 2J inches long, compressed, scattered, shattering moder- 

 ately; seeds black, large, 7^ to 8h mm. long, elliptical, slightly flattened;

 cent); flowers both purple and white; pods medium large, 2 to 2 J inches 

 long, tumid, crowded, shattering moderately; seeds olive-yellow, 

 medium-sized; 7J to 8 mm. long, oval; hilum pale; germ yellow. Grown 

 two seasons. 

 22381 B. A pure selection in 1908. Plants stout, erect, bushy; height 12 to 16 inches; 

 medium early; pubescence tawny; flowers white; pods large, 2 to 2^ 

 inches long, tumid, half crowded, shattering little; seeds olive-yellow 

 (smoky), large, 9J to 10 mm. long, elliptical, slightly flattened; hilum 

 pale; germ green. Grown one season. 



22406. Hongkong. From Hongkong, Kwangtung, China, 1908. Plants stout, erect, 



bushy; height 24 to 30 inches; medium late; pubescence tawny; flowers 

 both purple and white; pods scattered, shattering little. If to 2 inches 

 long, tumid; seeds black, medium-sized, 7^ to 8 mm. long, oblong, 

 slightly flattened; hilum pale; germ green. Grown two seasons. 



22407. Nigra. From Hongkong, China, 1908. Plants slendet, erect, the tips 



twining; height 24 to 30 inches; medium; pubescence gray (8 per cent) 

 and tawny (20 per cent); flowers both purple and white; pods medium- 

 sized. If to 2 inches long, tumid, scattered, shattering moderately; seeds 

 black, medium-sized, 8^ to 9 mm. long, oblong, much flattened; hilum 

 pale; germ green. Grown two seasons. 



22411. From Dammann & Co., Naples, Italy, 1908, as "Samarow." This proved 



to be identical with 172G0. 

 22411 A. A pure field selection in 1907. Plants stout, erect, bushy; height 12 to 16 

 inches; medium early; pubescence tawny; flowers purple; pods small, 

 IJ to IJ inches long, compressed, crowded, shattering much; seeds dull 

 brown, very small, 5 to 5^ mm. long, oblong, much flattened; hilum 

 pale; germ yellow. Grown two seasons. 



22412. From Dammann & Co., Naples, Italy, 1908. The plants were exactly like 



Chernie, 18227. 



22413. From Dammann & Co., Naples, Italy. Seeds brown, but none germinated. 



22414. From Dammann & Co., Naples, Italy, 1908. This is exactly the same variety 



as 21754. 



22415. From Dammann & Co., Naples, Italy, as "Giant Yellow." The plants 



and seeds of this can not be distinguished from Butterball, 17273. 

 22428. Wild soy bean from the botanic gardens, Tokyo, Japan, 1908. Plants very 

 slender, very vining, procumbent; length of stems 36 to 48 inches; 

 very late; pubescence tawny; flowers purple; pods small, f to 1| inches 

 long, compressed, scattered, shattering very much; seeds dull black, 

 oblong, much flattened, very small, 3^ to 4 mm. long; hilum pale; 

 germ yellow. Grown three seasons. (See PI. I.) No. 25138, from 

 Soochow, Kiangsu, China, is identical. (See PI. II, fig. 1.) This is 

 the wild form of the soy bean. It volunteers very readily at Arlington 

 Experimental Farm, the seedlings appearing about May 1. Were it 

 not that the seed shatters so badly, the plant would have promise as a 

 cover crop.
