ground, or from whence they originate, and, 

 m many forts, alfo the leaves ; in others the 

 leaves continue verdant; and fome have alfo 

 abiding ftems of a branchy growth, continu- 

 ing Summer and Winter, as in wall-flower, 

 llock-gi'iiflower, &c. which, however, feldom 

 in the fame individual remain longer tlian 

 two years before they dwindle to a weakly 

 declining ftate, more of a biennial than pe- 

 rennial nature ; though, as the double wall- 

 flowers particularly are multiplied and conti- 

 nued perennial, both in root and top, by 

 raifing them from cuttings of the top Ihoots, 

 they, anid, fome others of a fimilar nature, 

 are arranged here among the perennials, in 

 which the fame root continuing, and in moft 

 kinds multiply by ofF-fets, &c. they princi- 

 pally renew their flower-Hems annually, as 

 above intimated, and propagate by feed, flips, 

 ofF-fets, parting roots, and other different 

 methods, as hereafter fhewn. 



They con filUng principally of fibrous-rooted 

 plants, the roots are compofed of many fibrea, 

 which, in moil forts, are fmall and thread- 

 like, others thicker and more flefliy, fome 

 with long flefliy fangs ; and there are alfo 

 many tuberous-rooted kinds,, the roots being, 

 in fome, of a thick knobby flefliy fubftance, 

 fometimes only in one or two tubers, roundifli 

 or oblong, &:c. and in others of feveral toge- 

 ther, either in a loofe clufter, or fome clofely 

 connected in a head ; and by ofF-fets of the 

 <oots, numerous forts are propagated.
