Synonymes. Jiglans sp. Lin., Willd., Michz.; Hicdrius Rafinesque; Hickory, Amev. 
Derivation. ‘‘ Karua (Carya), the walnut tree: the name which the Greeks applied to Jdglans 
régia.” (Nuittall.) The name of Carya was applied to the common walnut by the Greeks, in 
honour of Carya, daughter of Dion, king of Laconia, who was changed by Bacchus into that tree. 
Diana had the surname of Caryata from the town of Garya, in Laconia, where her rites were 
always celebrated in the open air, under the shade of a walnut tree, Plutarch says the name of 
Carya was applied to the walnut tree from the effect of the smell of its leaves on the head. 
Gen. Char. Flowers unisexual, monecious. Male, female, and leaves all upon a 
shoot developed from one bud in the year of the flowering. The male flowers 
borne at the base of the shoot, below the leaves, or in the axils of the lower 
leaves ; the female flowers, a few together about the tip of the shoot.—Male 
flowers in slender pendulous catkins, that are disposed 3 upon a peduncle. 
Calyx a 3-parted minute leaf. Stamens4—6.—Female flowers, Calyx including 
and adhering to the ovary ; its tip free, and 4-cleft. Stigma sessile upon the 
ovary, partly discoid, 2—4-lobed Fruit a drupe. Husk fleshy, separating 
into 4 equal valves. Nué with 4 or more bluntish angles in its transverse 
outline ; the surface pretty even. (G. Don.) 
Leaves compound, alternate, exstipulate, deciduous ; imparipinnate, of 
5—15 leaflets, serrate; all, except the terminal one, in opposite, or nearly 
opposite, pairs ;-and all spreading in one plane. Flowers greenish. Decaying 
leaves brown. — Trees, deciduous; natives of North America; the rate of 
growth slower than a Jiglans, and the bark appearing reticulated. 
_ When propagated, the nuts should, if possible, be planted where the trees 
are intended to remain, as most of the species have very long taproots, which 
are nearly destitute of fibres. This remark, however, does not apply to C. 
amara, which, like Juglans nigra, has abundance of fibrous roots. The pig- 
nut (C. porcina) and the mocker-nut (C. tomentésa) are considered to afford 
the best timber; and the pacane-nut (C. olivaeformis) decidedly the best fruit, 
though the nut in this species is small. :
