Means of control 
In cultivated ground the weed succumbs to the constant tillage 
required, but such plants as spring up after the cultivator has 
ceased its rounds should be cut or pulled and should not be allowed 
to seed the ground. Autumn rosettes should be hoe-cut in spring. 
In meadows and grain fields the weed may be killed while young 
with a spray of Iron sulfate or Copper 
sulfate. 
FALSE FLAX 
Camélina sativa, Crantz 
Other English names: Wild Flax, Gold 
of Pleasure. 
Introduced. Annual and winter an- 
nual. Propagates by seeds. 
Time of bloom: June to August. 
Seed-time: July to September. 
Range: Ontario to Manitoba, south- 
ward to Ohio, Iowa, and South 
Dakota. 
Habitat: Flax and grain fields, clover; 
waste places. 
In Europe this plant is cultivated 
for the fine oil in its seeds and for 
mucilage, both of which are similar 
to the products obtained from flax 
seed. It was formerly believed that 
this plant was changed or degenerate 
flax, like Chess in wheat, and early 
writers spoke of it as Pseudo Linum, 
or False Flax. (Fig. 125.) 
Stem eighteen inches to three feet 
tall, erect, slender, smooth, branching Fie. 125.— False Flax (Ca-
