The aspen much resembles the large-toothed aspen in general habit, but these 

 two trees can be readily distinguished by their buds in winter and their leaves in 

 summer. 



As this tree is found in Canada over large areas where other timber is scarce 

 it is often cut into lumber and used in other forms, merely because it can be easily

obtained. It is a very valuable firewood in the Prairie Provinces. As lumber it

 almost exclusively for match sticks. 



POPULUS GRANDIDENTATA, Michx. LARGE-TOOTHED ASPEN 



Common names: Large-toothed aspen, big-toothed poplar, poplar. 

 French names: Grand tremble, peuplier a grandes dents.

 Brunswick westward, throughout Quebec and Ontario, south of the height of land 

 dividing the watersheds of the Great Lakes and Hudson bay. 



The large-toothed aspen is a medium-sized tree 40 to 50 ft. in height and 1 to 

 2 ft. in diameter. The top is narrow, round-topped, and very open. 



The bark on young trees is smooth and greenish-grey, on older trees it becomes 

 cracked. It resembles that of the aspen, except that on old trees it is not so deeply 

 furrowed. 



The twigs are stout, reddish-brown, and, at first, more or less downy. The 

 winter buds are shorter than those of the aspen and, on the whole, stand out more
