duncles arc taller, and have two or three narrow leaves on each, 

 placed aUcrnalely: on the top is one flower, willi long narrow, re- 

 flexed, peach-coloured florets in the ray: the disk is very prominent, 

 and of a dark purple colour: it flowers at tiie same time with the 

 third, but the flowers are of not so long duration. It is a native of 

 Carolina and Virginia. 



The fifth has the root perennial: the stalks four or five feet high: 

 the leaves narrow, smootli, opposite: the florets in ll;e ray of the 

 flower yellow, long, twelve in numljer: disk dark red: the scales of 

 the calyx spreading and almost awl-shaped. It is a native of Virgi- 

 nia, flowering in August and September. 



The sixth species is biennial: the lower leaves are divided into 

 three lobes, but those upon the stalks are undivided; ihey are hairy, 

 and shaped like those of the first sort: the stalks branch out on their 

 sides, and are better furnished with leaves than the others: the flowers 

 are very like those of the first sort, but smaller. It grows naturally 

 in several parts of North America. 



Cu/tuic.—AW the sorts of these plants may be increased by ofl- 

 sets, parting the roots and seeds. 



The oftsets in the perennial sorts should be taken oft' and planted 

 out in the early autumn: when the stems decay the roots may also 

 be divided and planted out at the same lime, or in the early spring 



months. 



As these plants are often liable to go off" soon, some should be 

 frequently raised to keep up the slock : and as others have a ten- 

 dency to become biennial, and decay without increasing the root, 

 they should have the flower-stems cut down in the early summer, to 

 encourage the growth of the root oflsets, for slipping in the following 

 autumn. 



All the sorts may be raised from seed, and the biennial sorts must 

 always be raised annually in that way; likewise such of the peren- 

 nial kind as are biennially inclined, sowing the seeds in April, in a 

 border of light earth, raking them in; and when the plants are tw^o or 

 three inches high, pricking llicm out in nursery-rows till autumn,
