LEAVES.--Alternate, compound, 8-12 inches long. Leaflets usually 5-7, sometimes 9, the upper 5-8 inches long, 3-4 inches broad; sessile, except the terminal; oblong- to obovate-lanceolate; minutely or sometimes coa.r.s.ely serrate; thick and firm; l.u.s.trous, dark yellow-green above, paler and more or less p.u.b.escent beneath. Petioles p.u.b.escent. Foliage fragrant when crushed.

FRUIT.--October; globose to globose-oblong, 1-1/2-2 inches long, with thick husk splitting nearly to the base; nut 4-ridged, red-brown, with very thick, hard sh.e.l.l and small, sweet kernel.
WINTER-BUDS.--Terminal bud 1/2-3/4 inch long, broadly ovoid, red-brown, pilose; outermost scales fall in early autumn.
BARK.--Twigs at first brown-tomentose, becoming smooth and grayish; on the trunk thick, hard, grayish, slightly ridged by shallow, irregular fissures, becoming rugged on very old trunks.
WOOD.--Very heavy, hard, strong, tough, close-grained, elastic, dark brown, with thick, whitish sapwood.
