248 Observations upon the effects of Frost. 



open ground at Kilkenny. C. speciosa escaped in a conser- 

 vatory at Spofforth, where Dillwynia ericifolia was de- 

 stroyed. The species of this genus are cultivated in Mr. Fox's 

 garden at Falmouth as hardy shrubs. 



Carmichaelia australis, though not much injured by the winter of 

 1836-7, was killed to the ground at Sketty, and even, trained to 

 a terrace wall with an eastern exposure at Carclew, it suffered 

 severely. It also died in the Botanic Garden of Belfast. 



Casuarina equisetifolia and stricta were killed on a south wall in 

 the Society's Garden ; the latter had been there for 7 or 8 

 winters. 



Calothamnus quadrifida lived in Mr. Fox's garden at Falmouth. 



Callistemon lanceolatus was only damaged in the Isle of Wight ; 

 this species and some others, trained against an east wall 

 where it flowers freely, was slightly injured at Carclew, where 

 other kinds in the shrubbery were rusty ; but the branches 

 were unhurt ; in Mr. Fox's garden, at Falmouth, it has lived 

 for 20 years as a hardy shrub ; in the Society's Garden it 

 was killed on a south wall. Callistemon speciosus appears 

 to have lived on a south wall at Kilkenny. 



Doryanthes excelsa, planted out 5 years, was killed at Bicton. 



Dianella ccerulea was killed to the ground at Carclew, but sprang 

 again. 



Dillwynia ericifolia perished in a conservatory at Spofforth. 



Eugenia australis, and Eutaxia myrtifolia, were both killed in 

 Mr. Fox's garden, at Falmouth. 



Eucalyptus pulverulenta was killed at Carclew, although pro- 

 tected by a double covering of mats. E. aljrina, 1-j foot high, 

 was found alive 6 inches above the surface at Norwich, having 

 been protected by the snow. All the species died in the So- 

 ciety's Garden, some of them having been fine specimens. At 

 Kilkenny, E. pulvigera was uninjured on a naked south wall. 



Grevillea rosmarinifolia, an elegant shrub, proved perfectly hardy
