(C. laciniosa) resembles much in size and appearance the 
common Shellbark ; but the nuts are double the size, the 
shell much ticker and yellowish, while that of the latter 
is white. It is but little known except west of the 
Alleghanies. The Mockernut hickory (C. tomentosa) is 
so called from the deceptive appearance of the nuts, 
which are generally of large size, but contain only a very 
small kernel. The leaves are composed of but four pairs 
of sessile leaflets, with an odd one at the end. The trunk 
of the old trees is very rugged, and the wood is one of the 
best for fuel. 
The Bitternut hickory ( C amara ), sometimes called the 
White hickory, grows 60 feet high in New Jersey. The 
husk which covers the nut of this species, has four winged 
appendages on its upper half, and never hardens like the 
other sorts, but becomes soft and decays. The shell is 
thin, but the kernel is so bitter that even the squirrels 
refuse to eat it. The Water Bitternut ( C . aquatica) is a 
very inferior sort, growing in the swamps and rice fields 
of the southern states. The leaflets are serrated, and 
resemble in shape the leaves of the peach tree. Both the 
fruit and timber are much inferior to those of all the other 
hickories.
