Carya carolinæ-septentrionalis Schn. Shagbark Hickory. [Illustration: Fig. 176] Leaves 4′—8′ long, with slender glabrous petioles, and usually 5 but occasionally 3 lanceolate long-pointed leaflets gradually narrowed at the acuminate symmetrical or unsymmetrical base, coarsely serrate, ciliate with long white hairs as the leaves unfold, thin, dark green above, pale yellow-green and lustrous below, the upper leaflets 3′—4′ long, 1′—1½′ wide, and about twice as large as those of the lower pair, turning dull brown or yellow-brown some time before falling. Flowers: staminate in slightly villose aments, glandular-hirsute on the outer surface, with linear elongated acuminate villose bracts; stamens 4; anthers puberulous; pistillate usually in 2-flowered spikes, oblong and covered with clustered golden hairs, their bract linear and ciliate on the margins. Fruit broader than high, or short-oblong, slightly depressed at apex, ¾′—1½′ wide, dark red-brown, roughened by small pale lenticels, the husk ⅛′—⅜′ thick, splitting freely almost to the base; nut ovoid, compressed, prominently 4-angled, acute at ends, nearly white or pale brown, with a thin shell; seed light brown, sweet. A tree, on moist bottom-lands sometimes 80° tall, with a trunk 2°—3° in diameter, and short small branches forming a narrow oblong head, or on dry hillsides usually not more than 20°—30° tall, with a trunk generally not exceeding a foot in diameter, and slender red-brown branchlets marked by numerous small pale lenticels and by the small low truncate or slightly obcordate leaf-scars, becoming ultimately dull gray-brown. Winter-buds: terminal ovoid, gradually narrowed to the obtuse apex, about ¼′ long, with glabrous bright red-brown and lustrous acute and apiculate strongly keeled spreading outer scales, the inner scales becoming when fully grown bright yellow, long-pointed, and sometimes 2′ long; axillary buds oblong, obtuse, not more than 1/16′ long. Bark light gray, ¼′—¾′ thick, separating freely into thick plates often a foot or more long, 3′ or 4′ wide, and long-persistent, giving to the trunk the shaggy appearance of the northern Shagbark Hickory. Wood hard, strong, very tough, light reddish brown, with thin nearly white sapwood. Distribution. Dry limestone hills, river-bottoms and low flat often inundated woods, frequently in clay soil; central North Carolina to northern Georgia, and through western North Carolina to eastern Tennessee, eastern Mississippi, and in Cullman and Dallas Counties, Alabama. 8.
