OSTKYA Scop. 



O. Virginiana (Mill.) Willd. Ironwood. Lever wood. Hop-tree. 



(0. Virginica Willd.) 



Commonly distributed throughout the State, in fair abundance 

 except in the southwestern counties, where it is reported as very 

 rare. A small tree, with a maximum height of about 40 feet 

 and a trunk diameter of from ten to twelve inches. Wood similar 

 in character to that of the Water Beech and used for the same 

 purposes. It is usually found on dry, sandy ridges, but occasionally

CORYLUS L. 



C. Americana Walt. Hazel-nut. 



Well distributed throughout the State and usually very abundant 

 where it occurs. It frequently forms dense thickets to the practical 

 exclusion of all other plant forms. In many counties it is so abun- 

 dant that the nuts furnish a considerable market product. It grows 

 usually in dry soils, but does well in moist, low grounds. 



Flowers in March and April ; nuts ripen in August, but are not 

 really edible until after frosts.

BETULA L. 



B. pofulifolia Marsh. American White Birch. 



This species occurs in Tippecanoe County, growing in moist soils 

 along the Wabash River. It occurs in sparing numbers. A tree 

 about 40 feet high and with a trunk- diameter of from 12 to 15 

 inches. The wood is soft and weak, being of no special value. 



Flowers in May.
