 nally from Tsangsheng, Kwangtung,

 lege. The growing season is 110 

 days, and the yield per acre is 1,280 

 pounds.

 crop, starchy variety of upland rice,

 land rice from Toishaan, Kwang-

 last year at the Canton Christian 

 College. The growing season is 110

 starchy variety of upland rice from 

 Ngwa, Kwangtung, which has been 

 growing at the Canton Christian 

 College for the last year. The grow- 

 ing season is 110 days, and the yield

69227. ROSA 



Rosaceae. 



Rose. 



No. 564. Kam ying lak. A wild rose 

 found widely distributed throughout 

 Kwangtung Province in hedgerows, on 

 uncultivated lands, and on mountain 

 sides. The plant is a rank grower and 

 does well even on the poorest soil. I 

 have not observed it, however, above an 

 altitude of a few hundred feet. The 

 dark-green shiny foliage is unusually fine, 

 being beautifully clean and free from 

 disease and insect injury. The single 

 pure white flowers with yellow anthers 

 are very large, about 9 centimeters in 

 diameter, and are produced abundantly. 

 I measured one flower last year which 

 was 11 centimeters in diameter. 



69228 and 69229. Pkttnus spp. Amyg- 

 dalaceae. Japanese flowering cherry. 



From Yokohama, Japan. Seedlings pur- 

 chased from the Yokohama Nursery Co. 

 Beceived March, 1925. Numbered Decem- 

 ber, 1926. 



69228. Prunus serrulata Lindl. 



Mazakura. This is a low. compara- 

 tively short-lived, much-branched tree 

 with small single white or pinkish flow- 

 ers, sparingly produced. It is the usual 

 stock on wbich Japanese nurserymen 

 graft the better varieties of Japanese 

 flowering cherries and is said to root 

 readily, in Japan, from hardwood cut- 

 tings planted in March. 



69229. Prunus serrulata spontanea 

 (Maxim.) Wilson. 



Yamasakura. A native Japanese cherry, 

 common on mountain sides from the ex- 

 treme southern part of Japan to about 

 the central portion. It becomes a tree 

 80 feet high, of spreading habit, with 

 single pink flowers, and is of value chiefly 

 because of its use as a stock for the 

 better varieties of flowering cherries.
