important that stockmen should be able to recognize these 

 plants, so as to destroy them whenever seen, or else to keep their 

 animals away from localities where they grow too abundantly to 

 be pulled out by hand. 



ALLIED SPECIES: Caraway (Carum carvi L.) has escaped 

 from gardens and become a troublesome weed in many places. 

 The roots are thick and fleshy and the whole plant bears a strong 

 resemblance to Wild Carrot. It is frequently prevalent 

 in waste places about gardens. 



Wild Parsnip (Pastinaca saliva L.) is a weed that is believed 

 to have escaped from cultivation; it is common about gardens 

 and old dwellings throughout eastern Canada. In appearance 

 it is not dissimilar to the cultivated kinds. The root is poisonous 

 and should be exterminated. If not spread over large areas, 

 the plant may be destroyed by applying a small handful of salt 

 to the root after the top is closely cut in hot dry weather. It 

 will not long survive continued thorough cultivation. 



Wild Carrot (Daucus Carota L.) is an objectionable weed 

 along roadsides, waste places, old meadows, and occasionally 

 gives trouble in cultivated fields, though not on land under 

 regular rotation of crops. Old meadows infested with it should 

 be broken up and cultivated for a few years. Sheep will suppress 

 it in pasture lands. The cultivated carrot probably origin- 

 ated from this wild plant. 



The seed (Plate 74, fig. 54) is characteristic of the family. 

 The main or primary ribs are inconspicuous while the secondary 

 ones are prominent, winged and armed with long prickles, which, 

 however, are easily rubbed off. Occasional in commercial grass 

 and clover seeds; most common in imported stocks. 



Idle weeds are fast in growth.
