MONOECl A POLYANDllIA. 
on the sides, and 2 obscure ones on the ends. Pericarp thick, separating 
into 4 parts. 
This is the most common species of this genus in the Southern States, 
and that which is in general exclusively meant by the generic name of Hick- 
ory; all of the other species have some peculiar epithet to distinguish them. 
The wood of this species, like that of the preceding, is used for many pur- 
poses by the Wheelwright, Millwright and Carpenter, and for fuel, the 
different species of hickory are preferred in this country to all other wood, 
one or two species of oak perhaps excepted. The nut of this species is well 
flavoured. 
The variety Maxima, Nutt, distinguished by its very large fruit, grows, 
though sparingly, on the sea-islands. 
It is certainly singular, that shoots of this species of Carya should be found 
disseminated over extensive tracts of pine barren, where it is very rare to 
discover a tree large enough to bear fruit. They are called Hickory Grubs, 
and are supposed to indicate a soil adapted for cultivation. 
Grows in rich soils. 
Flowers April.

A large tree. Leaves pinnate, leaflets generally 9, sessile, oblong-lan- 
ceolate, large, acutely serrate, glabrous on both surfaces, except the nerves 
and midrib, which are pubescent, almost tomentose. Fruit globular, the 
nut almost obcordate, very bitter, enclosed in a pericarp which in general is 
only divided to the middle. 
This species grows generally in very flat rich soils; and in the Southern 
States is, I believe as remarked by Michaux, universally confounded with 
the next species. 
Flowers April 
Leaflets generally 9, 
ovate oblong, acumi- 
nate, acutely serrate, 
? glabrous on both sur- 
aces; fruit nearly sphe- 
rical; nut smooth, mu- 
cronate, with the shell 
fragile.
