LXVII. JUGLANDA‘CEE !: CARYA. 735 
New England to Florida, in fertile soil in woods. Height 60 ft. to 100 ft. 
Introduced in 1656. Flowers greenish; April and May. Fruit with a 
green husk, enclosing a brown nut. 
Varieties. None are in cultivation; but a hybrid between this species and 
J. nigra has been noticed in p. 733. 
The growth of the tree is remarkably quick, more so than that of the Eu- 
ropean walnut. At 8 or 10 years of age it begins to bear, and age increases 
its fertility. No tree will grow under its shade, and even grass is injured by 
it. In 40 years, in good soil, it will attain the height of from 50 ft. to 60 ft. 
The heart-wood, which is black, remains sound for a long period, when ex- 
posed to heat and moisture; but the sap-wood speedily decays. When pro- 
perly seasoned, the wood is strong, tough, and not liable to warp or split. It 
is never attacked by worms, and has a grain sufficiently fine and compact to 
admit of a beautiful polish. The tree is universally raised from the nut, which, 
after being imported, ought to be sown immediately, as it seldom retains its 
vital power more than six months after it has ripened.

Spec. Char., §c. FPetiole villous. Leaflets, in a leaf, 15—17; lanceolate, 
rounded at the base, serrate with shallow teeth ; tomentose beneath ; lateral 
ones sessile. Fruit oblong-ovate, , 
with a tapered tip, downy, co- 
vered with viscid matter in small 
transparent glanded hairs, pen- 
dulous on a flexible peduncle. 
Nut oval, with an acuminate 
tip, very rough with prominent 
irregular ridges. (Michr.) A 
large deciduous tree. Canada to 
Virginia, and on the Alleghany 
Mountains. Height 30ft. to 60 ft. 
Introduced in 1656. Flowers 
greenish; April and May. Fruit 
a green husk, enclosing a brown 
nut ; ripe in October. 
This species grows with equal 
rapidity, when young, as the J. 
nigra ; butthe trunk ramifies at a 
less height; and the branches ex- 
tending more horizontally than 
those of most other trees, and 
spreading widely, a large and flat 
tufted head is formed, which gives 
the tree, in America, more espe- 
cially in exposed situations, a most remarkable appearance.
