Plants purchased from the Yokohama Nursery Company. A Japanese per- 
ennial belonging to the mustard family, with large, bright-green, heart- 
shaped, long-stemmed leaves and white flowers borne in clusters on a 
flowering stalk over 3 feet high. The long roots are about an inch 
in diameter, grayish, with many knots. In the humid valleys in Japan

superior in all ways. (Adapted from Vilmorin-Andrieux & Co., Les
