Chrysanthemum. L. 17. 2. 

 Is named from its yellow flowers ; many species ; some without 

 yellow flowers. 



C. leucanthemum. L. White Weed. Ox-Eye Daisy. The 



specific name is from its white flowers, so that the whole name 

 means white-flowered yellow-flower. The English name well char- 

 acterizes the appearance of the flower. 



A troublesome plant, spread over the fields and meadows of 

 many portions of this State, to the great annoyance of the farmer, 

 as it much diminishes the crop of grass, and is not itself much 

 relished by cattle or horses. The only method to eradicate it is, 

 early mowing before the seed is ripened, and, to be sure, as soon 

 as it begins to blossom. In a few years, this course must greatly 

 diminish it. A native of Britain. 



C. parthenium. L. Feverfew. An exotic from Europe, 

 often found in gardens. 



C. coronarium. L. The common Chrysanthemum of gardens, 

 affording beautiful flowers, a native of Sicily. 



In Europe C. Sinense, L., from China, is much cultivated as 

 one of the most beautiful of autumnal flowers. It is also cul- 

 tivated in this State. 



Achillea. L. 17. 2. 



Named from its fancied powerful properties, after Achilles, a 

 physician. Of near 50 species, nearly all belong to Europe and 

 the Levant. 



A. millefolium. L. Yarrow. Naturalized, and common by 

 fences and in fields ; is a plant of little consequence. 3 or 4 

 species are found in North America. The leaves are simple, but 

 greatly divided, so as to look like many ; hence the specific name. 

 A. ptarmica,L.) Goose Tongue, with leaves lanceolate, acumi- 

 nate, and sharply serrate ; introduced ; has been found in Dan- 

 vers, by Mr. Oakes.
