The Cultivated Poplars. 



225 



The name laurifolia, or "laurel-leaved," is generally applied in 

 this country to another plant, — Populus balsamifera, var. inter- 

 media. The name originated with the Russian botanist L,edebour, 

 and he published a good illustration of the tree he had in mind 

 and it is an admirable portrait of the large and crinkly leaves of 

 the tree which in this country goes under the name of Populus 

 Certinensis , — a name which, so far as I can learn, is simply a 

 garden or nursery name. No. 39 Riga, as I have it, is the same. 

 Neither am I able to distinguish 

 the tree grown in this country 

 as Populus Bereolensis. Koch* 

 mentions a Populics hybrida 

 Berolinensis as being a hybrid 

 between P. balsamifera and the 

 Italian poplar (or Lombardy), 

 but his tree is probably not 

 the same as the one grown in 

 this country.
