FOREST PLANTING LEAFLET. 



YELLOW POPLAR (Liriodendron tulipifera). 



FORM AND SIZE. 



The mature, forest-grown yellow poplar, or tuliptree, has a long, 

 straight, cylindrical bole, clear of branches for at least two-thirds of 

 its length, surmounted by a short, open, irregular crown. When 

 growing in the open the tree maintains a straight stem, but the crown 

 extends almost to the ground and is of conical shape. 



Yellow poplar ordinarily grows to a height of from 100 to 125 

 feet, with a diameter of from 3 to 6 feet and a clear length of about 

 TO feet. Trees have been found 190 feet tall and 10 feet in diameter. 



RANGE. 



Yellow poplar is distributed sparingly through southern New 

 England and New York; it is more plentiful on the southern shore 

 of Lake Erie and westward through northern Indiana and Illinois. 

 It extends southward into Alabama and the other Gulf States as far 

 as northern Florida. West of the Mississippi it is rare, except in 

 northeastern Arkansas and southeastern Missouri. It is most abun- 

 dant and of largest size in the south central part of its range, espe- 

 cially in Tennessee, Kentucky, and the western Carolinas, and in the 

 basin of the Ohio River and its tributaries. It is characteristic of the 

 distribution of yellow poplar that it is scattered by single trees or in 

 groups throughout the forest, and is rarely the predominant tree 

 except in the South, under especially favorable conditions. It is com- 

 monly associated with chestnut, the oaks, walnuts, hickories, maples, 

 black cherry, locust, and beech ; and is occasionally found with hem- 

 lock and white pine.
