Leaflets generally 9,

conspicuously mucro-

A large tree when growing in fertile soils, 60 — 80 feet high, 2—4 
feet in diameter. Leaves pinnate, leaflets 7 — 9- Sterile aments 3-parted, 
pendulous, 4 to 6 inches long. Scales 3-parted. Stamens A — 6. Fertile 
florets terminal. Nut oblong, conspicuously pointed, with a tapering sum- 
mit, angled, covered with a very thick, 4-parted pericarp. 
This, like all of the other species of Hickory, grows only in fertile soils. 
It is rare in the low country of Carolina; but the greater part of our hicko- 
ries resemble each other so closely in their leaves, and vary so much in their 
fruit, that it is very difficult to discriminate the species. This is remarkable 
for the thickness of its pericarp, from whence it is frequently called “thick- 
shelled Hickory. Its nuts are well flavoured. 
Flowers April.
