Wild Carrot. Daucus Carota L. An erect, 

 rough, bushy biennial, 30-90 cm. high; root 

 more or less fleshy; leaves variously lobed and 

 dissected; flowers white, umbels compound; 

 each half fruit bearing four vertical rows of 

 stiff bristles to aid in dissemination. These 

 bristles rub off when passing through a clover 

 huller. When ripe, the rays of the umbel 

 curve toward each other reminding one of a 

 bird's nest. One of our very worst weeds, 

 widely disseminated and rapidly spreading in 

 old pastures and roadsides. Introduced from 

 Europe. Wild carrot is simply the cultivated 

 carrot escaped from cultivation.

Wild Parsnip. Pastinaca saliva L. A 

 rather stout, smooth, biennial, 60-150 cm. 

 high, stem grooved, leaves pinnate: flowers 

 yellow; umbels compound; fruit flat, broadly 

 oval.
