POPLARS 



For the fastigiate variety of the Black Poplar see p. 134. 



Populus canadensis, Desf., is very similar in size and 

 habit, but usual Ij- with a more ovoid-pyramidal erowu, and 

 the twigs and young branches apt to be ridged with corky 

 lines, intensifying their angularity. 



iig. iu7. rojiiiliis iu()ra, Black Poplar. Bark (Irv). 



The Beech, when old, forms a widely spreading crown 

 of somewhat similar habit, but the branches come off at 

 smaller angles. Its buds, bark, &c., are entirely different 

 (see p. 167).
