FOREST PLANTING LEAFLET. 



COFFEETREE (Gymnocladus dioicus). 



FORM AND SIZE. 



The coffeetree when grown in the forest reaches a height of from 

 GO to 100 feet and a diameter of from 1J to 3 feet. The trunk tapers 

 but little and is often free from limbs for from 50 to 80 feet. The 

 branches are stout, pithy, and blunt and combine into a rather close 

 crown. 



When not crowded by other trees the trunk usually divides at from 

 10 to 15 feet from the ground into three or four branches, which 

 spread only slightly and form a narrow, round-topped head. 



RANGE. 



Although one of the rarest of our forest trees, the coffeetree is 

 equaled by few hardwoods in the extent of its range, growing as far 

 north as Montreal and south to Arkansas. Its geographical distri- 

 bution is from central New York and Pennsylvania west through 

 southern Ontario and southern Michigan to the valley of the Min- 

 nesota River, eastern Nebraska, Kansas, and western Oklahoma, and 

 south between the Mississippi River and the Allegheny Mountains to 

 Tennessee. This range has been somewhat extended by seeding from 

 cultivated trees. It is nowhere abundant, occurring only as a single 

 tree in localities most favorable to its growth. Over large areas 

 w r ithin its range it is entirely lacking or represented only by an 

 occasional individual. The coffeetree is associated with the ashes, 

 walnuts, hackberry, elms, basswood, cottonwood, honey locust, and 

 hickories.
