tute for the potato, is productive, and tlie tubercles keep for several months 

 without deterioration." {ArgoJlo Ferrao.) 



"Aerial tubers constitute the crop of this yam. The angular form of the 

 tuber suggests tlie name ' turlxey liver.' The tlesh is of a yellowish color and 

 very firm when cooked. The tubers are eaten boiled, fried, or baked. The 

 flavor is mild, and there is just a suggestion of sharpness in the taste, which 

 is in its favor." {R. A. Young.) 



For an illustration of these aerial tubers, see Plate II.

Flowering cherry.

 " In the Woods." Received June 8, 1919. 



''Doizen. Seeds from a tree at the southeast corner of my study. This tree, 

 in fact all the daizen trees on my place, have characterized themselves by their 

 regular fruiting habit, the cherry fragrance of their single white flowers, and 

 the vigor of their trunks and freedom from suckers. These trees have been 

 particularly free from disease and have struck me as promising for stock pur- 

 poses. They were bought originally from the Yokohama Nursery Co., Yoko- 

 hama, Japan, in the spring of 1906, and are now 13 years old and 20 feet or so 

 high, with trunks about 6 inches in diameter. 



" It is possible, of course, that the plants from these seeds will sliow the re- 

 sult of crossing with other varieties, such as Muraf<aki and Jobeni and Naden, 

 with which they are closely planted. Tliese varietal names are the ones at- 

 tached to the trees when they were sent by the Yokohama Nursery Co."

47568. DoLiCHOs lablab L. Fabacese. Bonavist bean. 



From St. Vincent, British West Indies. Presented by Prof. S. C. Harland, 

 assistant for cotton research. Agricultural Experiment Station. Received

"/S7. Vincent Bush. I discovered this type of l)ean in a peasant holding in St. 

 Vincent in the spring of 191.5 and found that it bred true when put into pedigree 

 culture. Under cultivation it produces a wiry bush from 18 inches to 2 feet in 

 height, and bears a heavy crop when environmental conditions are favorable. 

 As a cover crop iuv orchards in Florida I think it is worth a trial.
