in fevere frofts. And others, as the Lauruftinus (Viburniura 

 tinus) continue to fhoot and flower, unJefs the frofl is fevere 

 throughout the winter, fuftained by their vitality, or that prin- 

 ciple whofe exiftence preferves plants unhurt by cold before 

 flowering, but which ceafes to exift when the parts of frudi- 

 fication have performed their office ♦. 



The Lauruftinus is one of thofe plants that were introduced 

 to Ireland before green-houfes were known, confequently planted 

 in the open ground, and experience ftiews that it is feldom hurt 

 by froft. By it we find that fome plants, which to appearance 

 are not fitted for our climate, do yet outlive our winters ; and 

 that, without a knowledge of their native ftations, we may fome- 

 times fuppofe plants to be tender which are really hardy : thus 

 the Lauruftinus is unhurt by froft in Ireland until the cold 

 exceeds that of its own climate. The Ruddlea globofa and 

 Fufchia coccinea are other inftances of plants, that without a 

 knowledge of their native climate, Chili, we would not fuppofe 

 capable of being naturalized to ours. Yet is the Buddlea feldom 

 injured by our cold, and the Fufchia, although killed to the 

 ground by the winter's cold, fends forth abundance of fhoots 

 which attain the height of three feet in fummer, and are deco- 

 rated with its elegant flowers, which are larger and much more 

 brilliant than ever they are when confined in a houfe.
