FLOWERING PLANTS AND FEENS OF INDIANA. 995 



ANTHEMIS L. 



A. Cotula L. Common Dog-fennel. Mayweed. 



Very abundant, and very annoying, in almost every part of the 

 State. In dry soil along roadsides or in waste places. Easily rec- 

 ognized by its finely dissected leaves and disagreeable odor. 



Flowers continuously from June until the heavy frosts.

A. ARVENSIS L. 



Adventive from Europe. Seemingly established in a few lo- 

 calities. 

 Flowers July to September. 

 Monroe (Blatchley); Clark (Baird and Taylor). 



CHRYSANTHEMUM L. 



C. Leucanthemum L. Ox-eyed Daisy. Margarite. White Daisy. 



A troublesome weed in some of the southern counties, but be- 

 coming much less common in the northern part of the State. 

 Found in dry soils in waste places, also invading pastures and 

 meadows. Very difficult to eradicate when it has obtained a foot- 

 hold. Spread in some instances because of the use of the flower 

 in decoration, large patches having been noted as springing up at 

 the place where the wilted flowers were thrown. A very hand- 

 some form. 



Flowers from May through October. 



Daviess (Clements); Jefferson (Barnes); Jay, Delaware, Ean- 

 dolph, and Wayne (Phinney); Xoble (Van Gorder); Clark (Baird 

 and Taylor); Franklin (Meyncke); Dearborn (Collins); Putnam 

 (MacDougal); Kosciusko (Chipman); Hamilton (Wilson); Floyd 

 and Monroe; Marion (Moffatt). 



C. Parthenium (L.) Pers. Common Feverfew. 



Confined to the southern counties where it is found sparingly 

 in waste places adjoining old dwellings. It seems able to main- 

 tain itself, but does not spread to any extent. 



Flowers in June and July. 



Gibson and Posey (Schneck); Clark (Baird and Taylor).
