594 WEEDS : SPECIAL 



adopted with this weed, and especial care should be taken to 

 prevent its introduction in seed-corn and stable or yard dung. 

 In some of the worst cases we have seen the weed was brought 

 to the farm by dung containing the seeds. 



COMPOSIT.ffi — Coltsfoot (Tussilago Farfara L.) — A perennial 

 with thick stems growing horizontally at considerable depths 

 under ground. In early spring — March and April — stems bearing 

 scaly bracts come above ground, and carry at their tips a yellow 

 head of flowers resembling a large yellow daisy. The leaves in 

 shape are like the sole of a colt's foot, with downy undersurfaces-. 

 They appear after the flowers, sometimes not until the latter have 

 ripened their seeds and the wind dispersed them. This weed is 

 chiefly met with on damp stiff clays or moist chalky clays. Seeding 

 should be prevented, and the habit of flowering before the leaves 

 appear needs special attention, as it is the reverse of what 

 usually happens. 



The leaves of the established plants should be cut off" as soon 

 as they appear, and the process repeated several times with any 

 fresh ones which arrive later. In this way the plant may be 

 exhausted in one or two seasons. 



Draining is an efficient remedy, and digging up the plant, 

 taking care not to leave any pieces in the ground, exterminates 

 it, although the latter process is almost impracticable when it is 

 thoroughly established, as the depth to which it penetrates is 

 often 2 or 3 feet 



Stinking Mayweed, Stinking Chamomile {Anthemis Cotula 

 L.). — An annual plant with daisy-like heads at the ends of long 

 furrowed stalks. Among the flowers on the receptacle are scaly 

 leaves. It grows about i8 inches high, and possesses finely 

 divided, bipinnatifld, smooth leaves, which give out a fetid 

 smell, especially when bruised. Both this weed and the next 

 occur in corn fields and waste places, and may become trouble- 

 some if allowed to seed freely. 



Scentless Mayweed {Matricaria inodora L.) much resembles
