THE SUNFLOWER FAMILY 167 



Remedy: Sow clean grass and clover seeds. Do not allow 

 the plant to mature. Clean up waste places about farmyards 

 and seed to permanent grass that will take full possession of the 

 soil to the exclusion of this and other weeds. The plant is usually 

 prevalent in gardens fertilized with manure from city stables. 

 The seeds are not long-lived and the vitality of many would 

 be destroyed by piling the manure and allowing it to ferment 

 for a few months. 



ALLIED SPECIES: In the Maritime Provinces Scentless 

 Mayweed or Chamomile (Matricaria inodora L.) is commonly 

 found growing with the above. The two plants resemble each 

 other, but Scentless Mayweed is a much handsomer plant, 

 with flowers nearly 2 inches across and foliage of a dark, rich 

 green. It lacks the unpleasant odour. 



The seed is entirely different, being about 1/10 of an inch 

 long, square, somewhat flattened, dark brown except the margined 

 top and the 4 very prominent, wing-like ribs, present in some 

 seeds, which are generally much paler. 



Yarrow or Milfoil (Achillea Millefolium L.) is a well known 

 plant by waysides and in meadows throughout the ^Dominion. 

 A native form in the West occurs high up on the mountains as 

 well as on the prairies. The erect stems, 6 to 18 inches high, 

 bear flat-topped clusters of white flower heads and finely-divided, 

 fern-like leaves. 



The seed (Plate 76, fig. 82) is about 1/16 of an inch long, 

 gray with a white margin, flat and thin, oblong-wedge-shaped. 

 It is similar to the seed of Ox-eye Daisy, but flat, smooth^nd 

 ribless. Often found among seeds of the smaller grass. 



Who soweth his Barlej' too soon, or in Rain, 

 Of Oats and of Thistles shall after complain. 

 I speak not of May weed, of C!ockle and such. 

 That noieth the Barley so often and much.
