nter Buds and Leaves.=--Buds tomentose, ovate to oblong, terminal
buds large, much swollen before expanding; inner scales numerous,
purplish-fringed, downy, enlarging to 5-6 inches in length as the leaves
unfold. Leaves pinnately compound, alternate, 12-20 inches long; petiole
short, rough, and somewhat swollen at base; stipules none; leaflets
usually 5, sometimes 3 or 7, 3-7 inches long, dark green above,
yellowish-green and downy beneath when young, the three upper large,
obovate to lanceolate, the two lower much smaller, oblong to
oblong-lanceolate, all finely serrate and sharp-pointed; base obtuse,
rounded or acute, mostly inequilateral; nearly sessile save the odd
leaflet; stipels none.

=Inflorescence.=--May. Sterile and fertile flowers on the same tree,
appearing when the leaves are fully grown,--sterile at the base of the
season's shoots, in slender, green, pendulous catkins, 4-6 inches long,
usually in threes, branching umbel-like from a common peduncle;
flower-scales 3-parted, the middle lobe much longer than the other two,
linear, tipped with long bristles; calyx adnate to scale; stamens
mostly in fours, anthers yellow, bearded at the tip: fertile flowers
single or clustered on peduncles at the ends of the season's shoots;
calyx 4-toothed, hairy, adherent to ovary; corolla none; stigmas 2,
large, fringed.

=Fruit.=--October. Spherical, 3-6 inches in circumference: husks rather
thin, firm, green turning to brown, separating completely into 4
sections: nut variable in size, subglobose, white, usually 4-angled:
kernel large, sweet, edible.

=Horticultural Value.=--Hardy throughout New England; prefers light,
well-drained, loamy soil; when well established makes a moderately rapid
growth; difficult to transplant, rarely offered in nurseries; collected
plants seldom survive; a fine tree for landscape gardening, but its nuts
are apt to make trouble in public grounds. Propagated from a seed. A
thin-shelled variety is in cultivation.
