250 Observations upon the effects of Frost, 



winters, was killed very generally. At Carclew, in front of the 

 stove, the old stem escaped, but the branches were de- 

 stroyed; although much injured, it recovered during the 

 summer. 



Tristania laurifolia was killed under a verandah at Spofforth ; it 



was uninjured under a cold frame at Sketty. 

 Veronica decnssata was generally killed. At Carclew it had 



stood for years without injury in the shrubbery, but was killed 



to the ground with the exception of a few small twigs ; it 



however lived at Falmouth. 

 Westringia rosmarinifolia, in the same situation as the last, was 



killed at Carclew. 



California ; and Mexico. 



Abies grandis, nobilis, and amabilis, all proved hardy, even in 



the Society's Garden. 

 Berberis dealbata, a Mexican evergreen, in the open border in 



the Society's Garden, was killed to the ground ; but it came 



up again vigorously. A plant against an east wall sustained 



little injury. 



Bouvardia triphylla was generally killed, unless at Carclew, where 

 it becomes an herbaceous plant, flowering late every season 

 in the open border. 



Crataegus mexicana in the Society's Garden was much damaged 

 as a standard, but only slightly on a south wall ; it was un- 

 injured as a standard at Sketty. 



Ceanothus azureus, of which there were fine old plants on a 

 south wall in the Society's Garden, was killed to the ground, 

 but sprung up again. At North Stoneham it perished en- 

 tirely. At Carclew the young shoots of a plant in the shrub- 

 bery were killed back to the old wood ; but it recovered.
