AT 
found on hillsides and hill tops there are usually only a few in- 
dividuals, which indicates that the preference of the species is for 
moist soil conditions. 
The published records of the distribution are as follows: Clark 
(Smith); Clay (Wilson); Delaware (Phinney); Franklin (Meyncke); 
Gibson (Schneck); Hamilton (Wilson); Knox (Ridgway); Kosci- 
usko (Clark) and (Scott); Putnam (Wilson); Steuben (Bradner). 
Additional records are: Crawford (Schneck); vicinity of New 
Albany (Clapp); Putnam (Grimes) and (MacDougal); Tippecanoe 
(Coulter); Clark, Decatur, Fulton, Jennings, Marshall, Monroe, 
Montgomery, Noble, Owen, Porter, Posey, Steuben, Vermillion, 
Warren and Wells (Deam). 
Economic uses. Wood soft, light and not strong. Used prin- 
cipally for pulp and excelsior. The supply in Indiana is so limited 
as to be of no economic importance. The pioneers were accus- 
tomed to cut small quaking aspens into convenient sizes for tying 
in the stalls of their stables in order that their horses might gnaw 
off the bark which contains a bitter tonic principle. 
3. Populus heterophylla Linneus. LARrGE-LEAVED Corronwoop. 
Plate 21. Bark deeply furrowed, the furrows as wide as the ridges, 
reddish-brown; winter buds glabrous or with a few hairs, slightly 
resinous, about 6 mm. (14 inch) long; leaves ovate, 7-15 cm. (3-6 
inches) long, cordate or truncate at the base, velvety when 
young gradually becoming glabrous above and paler beneath and 
remaining somewhat pubescent, especially along the conspicuous 
veins, petioles round or but little flattened; flowering season March 
or April. 
Distribution. Connecticut south to Georgia and west to Louisi- 
ana and Missouri. In Indiana it is rare and local, except in the 
lower Wabash bottoms, where it is frequent or common around 
ponds and in sloughs. It grows in low woods and swamps. A 
medium sized tree, usually about 15-25 m. (48-80 feet) high and 
less than 5 dm. (20 inches) in diameter. 
The published records of the distribution are as follows: Dela- 
ware, Jay, Randolph and Wayne (Phinney); Franklin (Meyncke); 
Gibson (Schneck); Hamilton (Doane); Jay (M’Caslin); Knox 
(Ridgway); Miami (Gorby); Posey (Schneck); Vigo (Blatchley). 
Additional records are: Blackford, Laporte, Posey and Wells 
(Deam). 
Economic uses. Too rare to be of any economic importance.
