_Carya ovata (Mill.) K. Koch_ [_Hicoria ovata (Mill.) Britt._] [_Carya alba Nutt_.]
HABIT.--A tree 60-80 feet high, with a slender, columnar trunk 1-2 feet in diameter; forming a narrow, somewhat open crown of stout, slightly spreading limbs and stout branchlets.
LEAVES.--Alternate, compound, 8-14 inches long. Leaflets usually 5, the upper 5-7 inches long and 2-3 inches broad; sessile, except the terminal; obovate to oblong-lanceolate; finely serrate; thick and firm; glabrous, dark green above, paler beneath and glabrous or p.u.b.erulous.
Petioles stout, smooth or hairy. Foliage fragrant when crushed.
FLOWERS.--May, after the leaves; monoecious; the staminate hairy, greenish, in pendulous, ternate catkins 4-5 inches long, on a common peduncle about 1 inch long; scales 3-parted, bristle-tipped; stamens 4, with bearded, yellow anthers; the pistillate in 2-5-flowered spikes, 1/3 inch long, brown-tomentose; calyx 4-lobed, hairy; corolla 0; stigmas 2, large, fringed.
FRUIT.--October; globular, 1-2 inches long, with thick husk separating completely; nut usually 4-ridged, with thick sh.e.l.l and large, sweet, edible kernel.
WINTER-BUDS.--Terminal bud 1/2-3/4 inch long, broadly ovoid, obtuse, dark brown, pale-tomentose or nearly glabrous.
BARK.--Twigs brownish, more or less downy, becoming smooth and grayish; thick and grayish on old trunks, separating into thick strips 1-3 feet long, free at one or both ends, giving a characteristic s.h.a.ggy appearance.
WOOD.--Heavy, very hard and strong, tough, close-grained, elastic, light brown, with thin, whitish sapwood.
DISTRIBUTION.--Common in the Lower Peninsula as far north as Roscommon County.

HABIT.--A tree 60-80 feet high, with a tall, slender trunk 2-3 feet in diameter; forming a narrow, oblong crown of small, spreading branches.
LEAVES.--Alternate, compound, 1-2 feet long. Leaflets usually 7, the upper 5-9 inches long, 3-5 inches broad, larger than the lowest pair; sessile or short-stalked; oblong-lanceolate to obovate, taper-pointed; finely serrate; thick and firm; l.u.s.trous, dark green above, paler and soft-p.u.b.escent beneath. Petioles stout, glabrous or p.u.b.escent, often persistent on the branches during the winter. Foliage fragrant when crushed.
FLOWERS.--May, after the leaves; monoecious; the staminate in pendulous, ternate catkins 5-8 inches long, slender, yellow-green, on common peduncles 1 inch long; scales 3-lobed, tomentose; stamens 4, with yellow, hairy anthers; the pistillate in crowded, 2-5-flowered spikes, tomentose; calyx 3-toothed, hairy; corolla 0; stigmas 2, light green.
FRUIT.--October; oblong to subglobose, 1-3/4-2-1/2 inches long, with very thick, woody husk, splitting to the base; nut 4-6-ridged, with thick, hard sh.e.l.l and large, sweet kernel.
WINTER-BUDS.--Terminal bud about 1 inch long, ovoid, obtuse, dark brown, p.u.b.erulous.
BARK.--Twigs orange and more or less p.u.b.escent, becoming darker in the first winter, and finally grayish; on the trunk 1-2 inches thick, light gray, separating into broad, thick plates 3-4 feet long, persistent on the trunk for many years.
