Tenderness oj some well-known Plants. 119 



Willow-leaved, and one variegated Sweet Bay, the latter 

 was killed, while the others remained uninjured, in 

 1878-79 ; but last winter one of the first and the second 

 were also killed, while the other plant of the common 

 variety only lost the points of its shoots, with a few of its 

 small branches, and is now pushing fresh leaves and 

 young shoots. 



Lavateraarhorea{\\\QTr:ee, or Sea Mallow). — In an essay 

 recommending the use of a tall growing variety, which I 

 found in Arran, as a fibre plant for paper making, for which 

 I received the Highland and Agricultural Society's Gold 

 Medal in 1877, I mentioned that many of the plants suffered 

 when the thermometer fell to about 15° Fahr., and that most 

 of them were killed when it fell below 10° ; hence all of my 

 young plants perished in each of the last winters. Sown in 

 March of each year, the young plants of the tall variety 

 had obtained heiiihts of 6 to 8 feet before the winter set 

 iu, while those of the east coast or " Bass Kock" variety, 

 were only about two-tliirds of their size, but all seemed 

 equally tender, 



Passiflora coerulea. — A fine plant, which had grown for 

 eight years on the same wall as MuhlenhecMa complexa 

 was killed in the winter 1878-79, and a young one, planted 

 in spring 1879, was killed last winter. 



Populus fastigiata. — The fastigiate or Lombardy pop- 

 lar. A plant of the comparatively rare female form i)f 

 this well-known tree, from the noted specimen in the Uni- 

 versity Botanic Gardens at Gottingen, was scarcely injured ; 

 while of many of the common or male form, growing in 

 the neighbourhood, most were entirely killed, and the rest 

 suffered more or less severely. 



Roses. — Many uf the hybrid per[)utual and Chinese 

 varieties, which have of late years almost superseded the 

 old hardy sorts in cultivation, have either been killed or S(j 

 much injured by the severity of last winter, that only 

 comparatively few, weak, and unsatisfactory blooms need 

 be looked for this year. 



Veronica decussata was completely killed alongside of 

 V. Traversil (17) in 1878-79, and plants that were put 

 out in spring 1879 were destroyed last winter. The 

 recently-introduced fine hybrid shrubby Veronicas, that
