COMPOSITAE (COMPOSITE FAMILY) 
Nipplewort is nearly related to Chicory, 
and, like that plant, is used as a salad in 
its European home, though not grown 
for the purpose but instead considered a 
troublesome weed in cultivated fields. 
(Fig. 360.) 
Stem one to four feet high, slender, and 
much branched, smooth above but bristly- 
hairy near the base, all parts of the plant 
containing a somewhat bitter, milky 
juice. Lower leaves usually lyrate, the 
terminal segment being very large with 
shallow-toothed or wavy edge, but the 
lateral lobes very small, often mere 
pointed wings to the petiole; upper 
leaves sessile and few, usually entire. 
Heads very numerous, few-flowered, each 
about a quarter-inch broad, composed 
all of perfect and fertile golden yellow 
tay florets, growing in loosely branched 
clusters on very slender pedicels; invo- 
lucre cylindric, formed of a row of smooth 
linear bracts surrounded at base by a 
very few short outer ones. Achenes very 
small, pale brown, and without a pappus. 
Prevent seed production by cutting closely as soon as the first 
flowers appear and repeating the treatment as the plants recover 
and form new buds.
