owing, as it is supposed, to the great thickness of the bark, and a covering 

 of fern sufficient to keep off 20° of frost. 



Pterocarya caiicasica, commonly called Juglans fraxinifolia, in the posses- 

 sion of Mr. Dillwyn, was uninjured ; and at Woburn, although in an ex- 

 posed situation, it did not suffer. 



PisTACiA Terehinthus had only the ends of the shoots killed at Norwich, and 

 an old tree in the Apothecaries' Garden at Chelsea, was scarcely injured. 

 Neither did it suffer at Owston. P. narbonensis was killed to the ground in 

 the Society's Garden. At Abbotsbury, P. vera and Terehinthus were un- 

 harmed, but P. Lenfiscus died. 



Phlomis fridicosa, and ferruginea, perished in the Society's Garden, at Glas- 

 gow. The former was uninjured at Sketty. 



Peganum Harmala survived at Cambridge. 



PuNiCA Granatum was severely cut in the Society's Garden, on soutlt walls, 

 and P. 7iana was killed : but the former suffered little in many other places. 



QuERCUs coccifera was killed at Redleaf and elsewhere near London, but not 

 at Owston, nor RoUeston. 



Rhamnus Alaternus and all the varieties suffered severely near London, more 

 than Phillyreas; none were injured at Owston, or Sketty. R, balearica 

 escaped at Cambridge. 



Ruscus racemosus suffered little in bleak places near London. R. androgynus 

 escaped at Cambridge. 



RuTA graveolens was killed to the ground at Claremont and Dropmore, 

 but not injured in several places near London ; it was almost destroyed at 

 Glasgow. 



Santolina Chamce-ci/parhsus had its branches slightly injured at Cambridge. 



Salix hahylonica was not at all injured at Claremont, or near London, 

 although killed at Glasgow, as it often is in Scotland in less severe winters. 



Salvia officinalis was killed in many places about London, and much injured 

 elsewhere; it all died at Penllargare, but escaped unhurt at Sketty. 



Spartium viultifloi'um, acutifolium, and radiatum, were entirely killed in the 

 Society's Garden. At Belsay is a plant of Spartium cstnense, 5 feet high j 



r it was only a little weakened by the winter ; it grew from a single seed, 

 gathered by Sir C. Monck, on iEtna, in 1831 j it is highly ornamental in 

 August and September, and may be called generally hardy in England. Sp. 

 patens was killed at Spofforth, and Junceuin was cut to the ground. S. in- 

 festum perished at Abbotsbury. 



Tamarix gallica was killed to the ground in Middlesex, and to the north, in 

 some places, but not at Owston. T. afra, and Libanotis, were uninjured at 

 Abbotsbury. 



Vaccinium madeirense, which was cultivated at Claremont for its fruit, was 

 killed. V. Arctostaptiylos was much injured in the Garden of the Society. 



« CHILI, AND SIMILAR SOUTH AMERICAN REGIONS. 



Alstrcemerias sustained the cold in the open border surprisingly well. A. 

 pulchella lived in an open border in the Garden of the Society without 

 injury. A. psittacina was saved in a south border at Norwich. A. Pele- 

 grina, pulchella, ovata, hirtella, aurea, and one or two others, were uninjured 

 at the bottom of a wall at Claremont. Mr. Herbert reports, that at Spof- 

 forth the Alstrcemerias are all very flourishing ; a large bed of seedling 

 plants of aurea, covered with sawdust, began to show green sprouts in 

 March, and even a single plant of the Valparaiso variety, which might have 

 been supposed to be tenderer than the former from Chiloe, covered only 

 with a hatful of sawdust, pushed at the same time. 



Aloysia citriodora was killed to the surface of the ground in the midland 

 counties, but in the south of England only deprived of the young wood. 

 Several plants had remained for years uninjured at Sketty, but they were 

 affected in the winter of 1836-37, and were totally destroyedin the present
