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 Van 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.
