KoELREUTERiA pamciilala, grown as a hardy shrubbery plant, was uninjured 

 in England ; but suffered at Glasgow. 



Magnolia /wscato, trained to a wall, sustained no injury at Bicton ; M^puniila 

 died there. M. consjncua seems to have been hardy everywhere. 



An Orange tree, at Owston, of the variety called the Portogallo dolce, 

 trained to the back wall of a peach-house, escaped, protected by a few fir 

 branches and the upper lights only, with the thermometer down to 24P 

 several times ; after the lower hghts were put on without fire, the outdoor 

 thermometer fell to 10°, when the plant was injured, but it recovered. In 

 Cornwall species of the genus Citrus survived the winter, with little or no 

 protection. Mr. Fox's collection may be taken as an example of this. The 

 citron has been trained for 10 years to a south wall, is 5 feet high, and pro- 

 duces ' fine fruit.' The lemon, in a south-east exposure, has lived for 17 

 years, is 7 feet high, and produces plenty of fruit. A plant, called the 

 ' Citrus orange^ lives as a hardy shrub. The St. Michael orange has lived 

 23 years on a south wall, and produces an abundance of ' choice fruit' 

 annually. Finally, the Mandarin Orange has been living uninjured for three 

 years. 



PiNUS sinensis, supposed to be the only one in the country, had stood out of 

 doors 20 years at Redleaf, was 14 or 15 feet high, and was quite killed. 



PiTTOSPORUM Tobira was generally killed near London. At Sketty, since 

 1813-14, several shrubs had remained uninjured by the frost till last winter, 

 when they did not suffer more than some common evergreens, which grew 

 beside them, and one of them came freely into flower. Mr. Dillwyn states, 

 that in the scale of injury it may be placed with Arbutus Unedo, and that 

 it has suffered much less than Aristotelia Macqui. In Cornwall this is a 

 common shrub : several plants at Carclew were split from top to bottom, 

 and killed ; others had their last year's shoots killed; and only a few, which 

 happened to be protected by higher shrubs, escaped. At Falmouth it did 

 not suffer. 



Roses. Of the Banksian rose, both the yellow and white variety suffered 

 severely in all the northern parts of England ; atClaremont, plants 15 years 

 old, and covering 60 or 70 yards of wall, were killed to the ground ; fine old 

 specimens perished in the Society's Garden ; at Brenchley, a plant with a 

 stem 1 ] i inches in circumference, and covering the whole side of a house, 

 was entirely destroyed ; they equally perished in Hampshire, but it was 

 observed at Owston that one plant against a shaded wall escaped. The 

 varieties of Rosa multiflora were destroyed. Rosa bracteata, the Macartney 

 Rose, was killed back to its old wood, or even down to the ground. R. 

 microphylla suffered in the same degree ; other China roses in general were 

 killed to the ground, or totally destroyed. The white and yellow China 

 Rose, the sweet-scented hybrid, Hamon, and Blairii, were entirely destroyed 

 even in Hampshire; but the latter was injured on a south wall at Drop- 

 more. Generally speaking, the Noisette, Isle de Bourbon, and tea-scented 

 varieties, were found the most tender ; hybrids, between the China rose 

 and European species, were much less affected ; the beautiful Rosa ruga, a 

 mule between Rosa indica and arvensis, did not suffer in the least at Pit- 

 maston, or even at Redleaf, where the Noisette, and every description of 

 China Rose, was killed down to the ground. It was, however, very different 

 in Cornwall and South Wales ; at Carclew, Rosa involuaxda was the only 

 rose that suffered, while Rosa imcroiihylla close beside it was uninjured. 

 At Sketty, Rosa microphylla was slightly injured, but at that place no other 

 of a large collection was at all injured. At Penllargare ^.microphylla against 

 a wall was quite unhurt. R. sinica perished on a south wall in the Society's 

 Garden. 

 PjEONia Moutan and papaveracea did not suffer at all in the south of England, 

 nor even at Claremont in various exposed situations, or Glasgow, though 

 unprotected ; but at Redleaf three dozen large plants were so much injured, 

 that it was necessary to cut them down to the ground ; and I learn from
