UMBELLIFERAE (PARSLEY FAMILY) 



United carpels ovoid, nearly as broad as long, each of the two 

 having five sharply keeled ridges. These seeds may remain 

 dormant in the soil for several years and should never be 

 permitted to sow themselves. (Fig. 211.) 



Means of control 



If the infestation is new, hand-pull as soon as discovered and 

 destroy it. Being annual, it is necessary only to prevent seed 

 development in order to suppress the weed. 



MEADOW PARSNIP 



Thdspium aureum, Nutt. 



Native. Perennial. Propagates by seeds. 

 Time of bloom: June to July. 



Seed-time: August to September. 



Range: New York to the Carolinas, westward 



to Arkansas and Nebraska. 

 Habitat: Moist meadows, waste places, open 

 woodlands. 



When it first appears in the spring, the 

 young shoots of this plant sometimes give an 

 unpleasant flavor to dairy products; later the 

 cattle reject it, though it seems to be not so 

 noxious as other members of its tribe. 



Stems smooth, one to two feet high, with 

 few branches. Base leaves heart-shaped, 

 smooth, sharply toothed, long-petioled ; those 

 of the stem three-parted sometimes twice 

 ternate the lateral leaflets sessile or nearly 

 so, the terminal one stalked, long ovate to 

 lance-shaped, finely toothed. Flowers deep 

 golden yellow, the compound umbel about two 

 inches broad. Carpels small, ovoid or nearly 

 globose, smooth, the ribs standing out like 

 wings. (Fig. 212.) 



Ranging nearly with this plant is a close 

 relative, the HAIRY-JOINTED MEADOW PARSNIP
