distinguished from others by its deeply-cut leaves and long, slender 
petioles. The plant also produces many axillary buds at the base 
of each petiole when developed. As the plant grows older these 
buds send out long, white petioled leaves, which make it appear large 
and showy. 
Potherb-mustard cabbage is sold on the market and used by the 
Japanese exclusively as a seedling. It is packed in bunches about 6 
inches wide, 4 to 6 inches long, and about 2 inches thick. The vege- 
table has a pleasant flavor and should be more extensively used. The 
tender plants should be selected for table use. They should be 
washed thoroughly and prepared as directed for leaf-mustard 
cabbage. 
Radish Greens (Raphanus sativus longipimnatus) 
Chinese name : Loh-bak-choi-chai 
Japanese name: Koko-no-ka daikon 
Leaf: Compound, with leaflets arranged in pairs on each side of the petiole ; 
smooth, free from spines ; 4 to 6 inches long ; 2 to 3 inches broad ; margin or 
edge, scalloped (S, v. 1, p. 166). 
Root: White; 4 to 6 inches long; three-sixteenths to three-eighths inch in 
diameter. 
Eadish greens, seedlings or thinnings obtained as a by-product 
from the culture of the radish, are removed at intervals from the seed 
beds to make room for such growing plants as are to be retained for 
the production of the edible root. The culture of radish greens or 
daikon on a large scale calls for heavy initial seedings to assure a good 
stand. The seedlings are sold as ko-ko-no-ka daikon. They are 
cooked like the Chinese spinach. 
Radish greens is conspicuous on the market by reason of the long, 
white taproots, and it is tied in small bundles of 20 or more seedlings.

Spinach is a native of Persia. Boh-choi might be freely translated 
" an edible greens from the country of Persia." Spinach is a deli- 
cious greens for the cool season. It usually appears* on the local 
markets from November to February. Spinach is in demand by the 
people of both the Orient and the Occident and is a rich source of 
iron in the dietary. 
Because of its brittle nature spinach is sometimes wrapped for 
market in a leaf of lily or canna and tied securely with fiber. This 
prevents the breaking of the petioles in handling. Other vegetables 
which resemble true spinach are not so wrapped for market. Each 
bunch contains 4 to 6 plants and is about 12 inches long and 4 inches 
broad.
