256 TREES IN WINTER 



LARGE-TOOTHED ASPEN 

 Popple, Poplar. 



Populus grandidentata Michx. 



HABIT — Generally' a small tree 30-45 ft, in height with trunk diameter 

 of up to iy2 ft., at times reaching- much greater dimensions; resembling 

 the Small-toothed Aspen; spreading by means of root suckers. 



BARK Resembling that of Small-toothed Aspen though generally 

 with more yellow or buff color to young trunks and limbs. The older 

 trunks seem to be rather less deeply furrowed. 



TWIGS — Stout, round, reddish-brown or somewhat yellowish-brown, 

 in early winter often more or less pale-downy in protected portions, 

 older twigs greenish-gray, otherwise resembling Small-toothed Aspen. 



LiEAF-SCARS — Resembling Small-toothed Aspen though the rather 

 larger stipule-scars are often indistinct or absent. 



BUDS — Averaging larger than those of Small-toothed Aspen, ovate to 

 conical, pointed, generally divergent, dull, dusty-looking, due to 'fine, 

 close, pale wool, especially at margins of scales; flower buds larger 

 and thicker. BUD-SCALES — light chestnut brown with scarious mar- 

 gins: first scale of bud anterior. 



FRUIT — ^A catkin of small capsules with hairy seeds ripening in 

 spring.

 toothed Aspen with which it is frequently confused. For points of 

 distinction see under the latter species. The Lombardy and Carolina 

 Poplars are distinguished by their yellow twigs and smooth buds; the 

 Balsam Poplar by its shining fragrant resinous buds; the Silver Poplar 

 by its generally more delicate, greenish twigs which are cottony- 

 woolly at least toward the apex.

 more.

 of annual growth, weak and soft, used in manufacture of paper, 

 excelsior, and to a small extent for woodenware.
