This species becomes also a large tree, and bears much resemblance to 
the preceding. Its leaves are pinnate, leaflets oblong-lanceolate, (15 — 19) 
very pubescent. The habit and fructification very similar to that of the pre- 
ceding species, but the fruit is oblong, with a protuberant summit; the nut 
oblong, acuminate, much more deeply and irregularly sculptured. The 
wood, though somewhat similar to that of the Black Walnut, is said to be in- 
ferior. The decoction of its bark has long been used and celebrated in the 
Northern States as a cathartic medicine. Its nuts are so oily and so soon 
grow rancid, that I believe they are never eaten. 
This tree, so commonly known to the inhabitants of the United States as 
the Butter-Nut, is said by Michaux to inhabit the mountains of Carolina and 
Georgia. I believe it has never been found along the sea-coast of these two 
States. 
Grows in fertile soils. 
Flowers in April.
