106 GROUND FEEDS. 
The plant grows in grain fields and waste places 
throughout the country, but more plentifully east of Lake 
Superior. ‘Jt is an erect plant six inches to 
two feet high, with dark green, lance-shaped, 
sparsely toothed leaves, and flowers one-fifth’ otf 
an inch in diameter, in clusters an inch across at the tips 
of elongating racemes. 
The slender seed pods are erect, on spreading stalks. 
They are one-half to one inch long, and four-angled. The 
small seeds, one-twenty-fourth of an inch long, are red- 
dish yellow with the scar end darker. Their characteris- 
tic bitter taste as well as their microscopic structure 
afford a good means of identification. 
The Plant 
and Seed 
WILD RADISH—Raphanus Raphanistrum L. 
The effects of Wild Radish are very similar to those of 
Wild Mustard. Its acridity, according to Long, produces 
pronounced intestinal disorders. 
The plant, like many others, is an introduced one. It 
is present in serious quantities only in the eastern pro- 
vinces and states, but is found also in British Columbia 
and California. It grows one to two feet high, with a 
few widely spreading branches quite low on the stem. 
The pale, yellowish green leaves are deeply lobed and 
provided with a few stiff bristles. The flowers are fewer 
and larger than those of Wild Mustard and are con- 
spicuously veined. The pods are swollen and jointed, 
with partitions between the seeds. When ripe, the pod 
breaks at the joints, and the seeds are shed, each enclosed 
in its own portion of pod. 
The seed itself is about one-eighth of an inch long, oval, 
irregular, and slightly flattened. It may, however, vary 
greatly in size and shape. The finely netted surface is 
reddish brown in colour.
