This species, which is found in upper Louisiana, is called by the French 
of Illinois and New Orleans, Pacanier, and its fruit Pacanes. This name 
has been adopted by the inhabitants of the United States, who call it Pe- 
cannut. On the borders of the rivers Missouri, Illinois, St. Francis, and 
Arkansas, it is most abundantly multiplied : it is also common on the river 
Wabash ; on the Ohio, it is found for 200 miles from its junction with the 
Mississippi : higher than this, it becomes more rare, and is not seen beyond 
Louisville. My father, in traversing this country, learned from the French 
inhabitants, who ascend the Mississippi in quest of furs, that it is not found 
on that river, beyond the mouth of the Great Mackakity, which discharges 
itself in the latitude of 42° 51k* 
This, tree grows most naturally in cold and wet grounds. There is a 
swamp of 800 acres, situated on the right bank of the Ohio, opposite to the 
river Cumberland, which is said to be entirely covered with it, and. which 
is called by the French, la pacaniere. 
The Pecannut is a beautiful tree, with a straight and well-shaped trunk; 
in the forests, it reaches the height of 60 or 70 feet. Its wood is coarse- 
grained, and like the other Plickories, heavy and compact : it possesses 
also great strength and durability ; but in these respects, it is inferior to 
some species hereafter to be described. Its buds, like those of the 
Black Walnut, and Butternut are uncovered. The leaves are from 12 to 
18 inches in length, and are supported by petioles somewhat angular, and 
slightly downy in the spring. Each leaf is composed of 6 or 7 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 2 to 3 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
