Horticultural value. Grows rapidly, adapted to all kinds of soil, 

 though its preference is for a moist rich soil, propagated either by 

 cuttings or seedhngs, transplants easily, stands pruning well, com- 

 monly develops a broad and open crown, leaf period long and has 

 few insect or fungous enemies. It is valued as a shade and orna- 

 mental tree. An objectionable character of this tree is its habit of 

 sending up shoots from the roots. 



2. Populus grandidentata Michaux. Quaking Asp. Cotton- 

 wood. Popple. Plate 20. Bark smooth, grayish-green, becoming 

 furrowed and dark brown on the trunks of old trees that grow in 

 the northern part of the State, especially when found growing in 

 swampy conditions. In the southern part of the State where the 

 tree grows on the top of hills the bark does not darken so much and 

 frequently remains a light gray to maturity or becomes only a dark 

 gray color; shoots at first hairy, becoming smooth at the end of the 

 season; leaves broadly ovate with large and irregular teeth, short 

 pointed, truncate or slightly heart shaped at the base, hairy when 

 expanding, smooth at maturity; petioles strongly flattened at right 

 angles to the plane of the blade; staminate catkins 2-8 cm. (1-3 

 inches) long, the pistillate catkins at maturity reaching 6-12 cm. 

 (234-5 inches) in length; stamens less than 15; flowering season 

 March, April or May. Trees usually about 10-20 m. (30-65 feet) 

 high and less than 4 dm. (16 inches) in diameter. 



Distribution. Nova Scotia, Ontario and northern Minnesota, 

 southward to the Ohio River and along the Alleghany Mountains 

 south to North Carolina. Locally distributed in all parts of In- 

 diana. It is frequent or common in swamps, along the border of 

 streams or in drier situations. In the northern part of the State 

 it is generally found in moist conditions and exceptionally found in 

 dry situations, while in the southern part of the State it is found 

 either in moist conditions along streams or in dry situations such as 

 the tops of hills. In Montgomery County along Sugar Creek it was 

 noted on a high ridge associated with the hemlock. In moist con- 

 ditions along streams it is usually found growing in colonies. When
