Observations upon the effects of Frosty 



observed, that the broad leaved variety, in no part of his 

 grounds, was more injured than some of the common ever- 

 greens which grew by its side, and till last winter it had 

 hardly suffered at all since the winter of 1813-14; the small 

 leaved variety, which never appeared to be equally hardy, 

 was, however, killed, or nearly so. At Owston all the bushes 

 were killed down, but shot up again. 



Nerium Oleander. Of two plants, which had thriven without 

 protection since 1834, one was killed by the winter of 1836-7, 

 and the other last winter, at Sketty. 



Olive. Of the common cultivated kind, almost every specimen 

 was killed to the ground, or more frequently wholly destroyed 

 in England ; even in the warm garden of Abbotsbury, in Dor- 

 setshire, this occurred, but in the garden of the Society, a 

 hardy variety, obtained from Nikita in the Crimea, through 

 the good offices of Mr. Buckatzsch of Guben, sustained no 

 injury. Olea europcea, var. buxifolia is also reported by Mr. 

 Dillwyn to have survived without protection at Penrice 

 Castle, without having been injured. 



Narcissus (Corbularia) serotinus, in a dry border at Spofforth, had 

 pushed its leaves before the frost, and they remained un- 

 hurt ; none of the species belonging to the Daffodil section 

 were touched ; but those of the Hermione section, from Italy 

 and Malta, suffered very much. 



Paliurus aculeatus had its branches much injured at Cambridge, 

 but is not mentioned in any other of the reports as having 

 suffered ; except at Glasgow. 



Phillyreas. Of the species of this genus the oleifolia, rosma- 

 rinifolia, and other entire leaved species, proved most delicate ; 

 the serrated kinds lived as far north as Owston. At Clare- 

 mont, P. latifolia hardly suffered at all, and, in the Society's 

 garden, this species and P. obligua proved perfectly hardy. 



Pinus. The only European species of this genus which sus-
