found in Upper Louisiana, 

 is called by the French of 

 Illinois and New Orleans, 

 Pacanier, and its fruit Pa- 

 canes. This name has also 

 been adopted by the inhabi- 

 tants of the United States, 

 who call it Pacanenut. On 

 the borders of the Missouri, 

 Illinois, St. Francis and 

 Arkansas, it is most abun- 

 dantly multiplied ; it is also 

 common on the river Wabash; 

 on the Ohio, it is found for 

 200 miles from its junction 

 with the Mississippi. This 

 tree grows most abundantly in cold and wet grounds. 



The pacanenut is a beautiful tree, with a straight and well- 

 shaped trunk ; in the forest it reaches the height of 60 or 70 

 feet, with a proportionate diameter. Its buds, like those of the 

 black walnut and butternut, are uncovered. The leaves are 

 from twelve to eighteen inches in length, and are supported by 

 petioles somewhat angular, and slightly downy in the spring. 

 Each leaf is composed of six or seven pair of sessile leaflets, 

 and terminated by a petiolated odd one, which is commonly 

 smaller than the pair immediately preceding. The leaflets, on 

 flourishing trees, are from two to three inches long, ovate, serrate, 

 and remarkable for the circular form of the upper edge, while 

 the lower one is less rounded. It is also to be noticed, that the 

 main rib is placed a little below the middle of the leaflet. The 

 nuts, which are usually abundant, are contained in a husk, from 

 one to two lines thick, and have four slightly prominent angles, 

 corresponding to their internal divisions. They vary in length
