WALNUT FAMILY 
Hicoria alba evidently gained the common name Mocker- 
nut because of the disappointing character of its nuts. These 
are usually of large size and look like Shellbark nuts, but they 
keep their promise to the sight only to break it to the hope, 
for the kernel is very small and very difficult to extract. 
The Mockernut varies toward the Shellbark on one side 
and the Pignut on the other. In its foliage it resembles the 
Shellbark, in its bark it resembles the Pignut. Its distin- 
guishing characters are its nuts, its large leaves of seven to 
nine leaflets, its large terminal bud and the pleasant resinous 
fragrance of its leaves. 
PIGNUT 
ficoria glabra, Cdrya porcina. Carya microcdrpa. 
Common throughout the northern states, ranges south as far as 
Florida and southwest to Texas. Prefers dry ridges and hillsides, 
but tolerates many different conditions. Rises to a hundred feet in 
the forest, but in the open is shorter, with a narrow head of slender, 
sometimes pendulous branches. Has the stout tap roots of all the 
hickories. 
Bark.—Light gray with shallow fissures and close appressed scales, 
rarely exfoliate. Branchlets slender, marked with pale lenticels, at 
first slightly angled, pale green, scurfy or downy ; later they become 
light red brown, smooth, and finally turn dark gray. The leaf-scars 
are comparatively small, semiorbicular to oblong, obscurely lobed, 
slightly emarginate at apex. 
Wood.—Kither dark or light brown, sapwood nearly white ; heavy, 
hard, close-grained, tough and elastic. Largely used in the manu- 
facture of agricultural implements. Sp. gr., 0.8217; weight of cu.

Winter Buds.—Terminal buds one-fourth to one-half of an inch 
long, narrow-oval, acute, or obtuse, two or three times as large as 
the axillary buds. The outer scales are acute, often slightly keeled, 
frequently long pointed at apex, reddish brown, beginning to unfold 
early in autumn, frequently fall before winter or early in spring. 
The inner scales increase in size when spring growth begins, fre- 
quently becoming two and a half inches long, and one and one-fourth 
inch wide, lanceolate to obovate, yellow green, more or less tinged 
with red, downy and persistent until the leaf is half grown. 
Leaves.—Alternate, compound, eight to twelve inches long. Leaf- 
lets five to seven, rarely nine. Variety mcrocarpa habitually five.
