nearly allied to the Daisy, and its seeds also 

 are destitute of pappus ; but it is easily distin- 

 guished by its involucre, which is scaly, and by 

 the flower forming a kind of depressed globe in 

 the bud. The scales of the involucre are 

 strongly marked, from being edged with a thin 

 membrane, and the florets of the ray are much 

 longer in proportion to those of the disk than 

 in the Daisy. The great Ox-eye Daisy, which 

 was formerly called Chrysanthemum leucanthemum^ 

 is now placed in a new genus, and called Leu- 

 canthemum vulgar c; and the Chinese Chrysan- 

 themums have been removed to the genus Fyre- 

 thrum. Both plants, however, will no doubt long 

 continue to be called by their old names. The 

 beautiful yellow-flowered plant often found grow- 

 ing among corn {Chrysanthemum segetum), the 

 three-coloured Chrysanthemum (C tricolor or 

 carinatum)^ and the yellow annual Chrysanthe- 

 mum (C coronarium), with some others, have 

 been left by Professor De CandoUe in their old 

 genus. In the Feverfew (Pyrethrum)^ the re- 

 ceptacle is elevated, and the fruit is crowned 

 with a narrow membrane. The Pellitory of 

 Spain was formerly considered to belong to this 

 genus, and afterwards to the Chamomile, but it 

 is now called Anacyclus Pyrethrum. Matricaria 

 Chamomilla^ the wild Chamomile, has also no 

 pappus; and in this plant the receptacle is
