CAPPARIDACEAE (CAPER FAMILY) 
Although it produces seed in plenty, the worst part of this weed 
is underground ; it springs from a small tuber about the size of a 
kernel of corn, attached to a slender rootstock on which there are 
other tubers, all of which will send up new plants during the present 
or the coming spring. Cows sometimes eat of the plant when first

turned out to graze in spring, seeming to relish 
its pungent, bitter taste, the taint of which 
is communicated to the milk. (Fig. 140.) 
Stem very slender, smooth, six inches to a 
foot in height. Base leaves about an inch 
broad, nearly circular or sometimes heart- 
shaped, smooth, entire, with long, slender 
petioles; those on the stem broadly lance- 
shaped, sessile, often entire, others slightly 
toothed. Flowers in rather large, loose clus- 
ters at the top of the stalk, white, and about 
a half-inch broad. Siliques about an inch 
long, flattened, very slim, tapering at each 
end, nearly erect. 
Means of control 
Cleanse infested grass lands with better 
drainage, for if they lack moisture the tubers 
will die. Plants of brooksides and ditches 
should be cut with hoe or scythe in the 
spring, if they are likely to come within 
reach of grazing milch cattle.
