The wood is heavy, very hard, tough, strong, flexible, 
close-grained, and is used for the same purposes as the 
wood of the preceding species. The fruit is about two 
inches long or less and about two-thirds as thick. The nut 
is about an inch in length and is sweet and edible. The 
species has a rather limited distribution in Iowa, but in 
some localities it is very common. In Appanoose county, 
along the Chariton bottoms, are many fine trees; in fact, 
the species is common along the river throughout its 
course in the county, and in times past many hundreds of 
bushels of nuts were gathered and sent to northern and 
eastern markets. Farther west in Decatur county a num- 
ber of trees were to be found in the valley of Grand river. 
We have seen specimens in the State university herbarium 
from Muscatine, Louisa, and Yan Buren counties; Messrs. 
Nagel and Haupt report the species from Scott county, 
Professor Shimek from Clinton and Wayne counties, Pro- 
fesor Macbride doubtfully from Johnson county; and we 
are creditably informed that the species occurs in Jefferson 
county.
