value. Some considerable areas are still found, remote from means 

 of transportation, in which it still abounds, and considerable care is 

 being exercised in the conservation and protection of the second 

 growth. The tree reaches a height of from 100 to 150 feet and a 

 trunk diameter of from five to ten feet. It is found chiefly in rich 

 bottom lands and on hillsides. Its great value suggests it as a suit- 

 able species for reforestration purposes. Its uses are too well known 

 ito need mention. Two well-marked varieties, recognized by lumber- 

 men and nut-gatherers, exist in our area ; they are not, however, 

 considered as botanically distinct. 



Flowers in April and May ; nuts ripen after the heavier frosts. 



Distribution general. 



J. cinerea L. Butternut. White Walnut. 



Generally distributed throughout the State in fair abundance, ex- 

 cept in the southwestern counties in which it occurs exceptionally. 

 A tree from sixty to eighty feet in height and of a trunk diameter 

 of from two to three feet. It grows chiefly in rich woodlands and 

 reaches its greatest development along the Ohio River, where it oc- 

 casionally reaches a height of one hundred and ten feet. 



The wood is light and soft, not strong, easily worked, taking a 

 beautiful polish. Used chiefly for interior finish, cabinet work, etc. 



Flowers in April and May ; fruit ripens with the frosts. 



Distribution general. 



HICORIA Raf. 



H. Pecan (Marsh.) Britton. Pecan. 



(Carya olivcdformis Nutt.) 



Found in southern and southwestern counties in considerable 

 abundance and following the river courses in less numbers well to 

 the north. It grows in bottom lands and alluvial soils. A tree 

 from one hundred to one hundred and sixty feet in height and with 

 a trunk diameter of from three to five feet. 



The wood is heavy and hard, but brittle, and much less valuable 

 than that of other hickories. It is used locally for wheel stock and 

 fuel. Its sweet, edible nuts form an important article of com- 

 merce. 



Flowers in April and May ; fruit ripens in September and Oc- 

 tober.
