Occasionally cultivated; hardy in the Arnold Arboretum.
3. CHIONANTHUS L.
Trees or shrubs, with stout terete or slightly angled branchlets, thick pith, and buds with numerous opposite scales. Leaves simple, conduplicate in the bud, deciduous. Flowers diœcious or rarely polygamous, on elongated ebracteolate pedicels, in 3-flowered clusters terminal on the slender opposite branches, of ample loose panicles, with foliaceous persistent bracts, from separate buds in the axils of the upper leaves of the previous year; calyx minute, deeply 4-parted, the divisions imbricated in the bud, persistent under the fruit; corolla white, deeply divided into 4 or rarely 5 or 6 elongated linear lobes conduplicate-valvate in the bud, united at base into a short tube, or rarely separate; stamens 2, inserted on the base of the corolla opposite the axis of the flower, or rarely 4 in the staminate flower, included; filaments terete, short; anthers ovoid, attached on the back below the middle, apiculate by the elongation of the connective, 2-celled, the cells opening by longitudinal lateral or subextrorse slits; ovary ovoid, abruptly contracted into a short columnar style; stigma thick and fleshy, slightly 2-lobed; in the staminate flower of the Asiatic species reduced to a minute subglobose body; ovules laterally attached near the apex of the cell; raphe ventral. Fruit an ovoid or oblong, usually 1 or rarely 2 or 3-seeded thick-skinned drupe tipped with the remnants of the style; flesh thin and dry, stone thick-walled, crustaceous. Seed filling the cavity of the stone, ovoid; seed-coat chestnut-brown.
Chionanthus inhabits the middle and southern United States with one species, and northern and central China with another.
The specific name, from χιών and ἄνθος, is in allusion to the light and graceful clusters of snow-white flowers.
1. [Chionanthus virginica] L. Fringe-tree. Old Man’s Beard.
Leaves ovate or oblong, acuminate, short-pointed or sometimes rounded at apex, gradually narrowed and cuneate below, entire, with undulate margins, and coarsely reticulate-venulose, yellow-green and lustrous above, pubescent below, and ciliate on the margins when they unfold, and at maturity 4′—8′ long, ½′—4′ wide, thick and firm, dark green on the upper surface, pale and glabrous on the lower surface except on the stout midrib and conspicuous arcuate primary veins more or less covered with short white hairs; turning bright clear yellow before falling early in the autumn; petioles stout, puberulous, ½′—1′ in length. Flowers slightly and agreeably fragrant, appearing when the leaves are about one third grown, in loose pubescent drooping panicles 4′—6′ in length, the bracts at the base of the lower branches of the inflorescence oblong, glabrous on the upper surface, pubescent on the lower surface, and sometimes 1′ long, those at the base of the upper branches oval, successively smaller, and gradually passing into the minute laciniate bracts subtending the lateral pedicels of the 3-flowered clusters terminating the last divisions of the panicle; some individuals bearing occasional perfect flowers among others functionally diœcious, some with sterile or rarely perfect anthers and a well-developed stigma, and others with an imperfectly developed stigma and fertile anthers; calyx light green, glabrous, with acute entire or laciniately cut lobes; corolla 1′ long, marked on the inner surface near the base by a row of bright purple spots; anthers light yellow, with a green connective. Fruit ripening in September, in loose few-fruited clusters, their bracts leaf-like and sometimes 2′ in length, oval or short-oblong, 1′ long, dark blue or nearly black, and often covered with a glaucous bloom; seeds ⅓′ long, ovoid, narrowed at apex and covered with a thin light chestnut-brown coat marked by reticulate veins radiating from the hilum.
A tree, 20°—30° high, with a short trunk 8′—10′ in diameter, stout ashy gray or light brown branches forming an oblong rather narrow head, and stout branchlets light green and covered with pale pubescence or sometimes glabrous when they first appear, terete or slightly angled in their first winter, often much thickened below the nodes, light brown or orange color, and marked by large scattered darker colored lenticels and by the elevated semiorbicular leaf-scars displaying a semicircular row of conspicuous fibro-vascular bundle-scars; often a shrub, with several stout thick spreading stems. Winter-buds broad-ovoid, acute, ⅛′ long, with about 5 pairs of scales increasing in length from the outer to the inner pair, ovate, acute, keeled on the back, light brown and slightly pilose on the outer surface, bright green and lustrous on the inner surface, and ciliate on the margins with scattered white hairs, those of the inner pair at maturity obovate, gradually narrowed below, foliaceous, and 1′—1½′ long. Bark of the trunk ¼′—½′ thick, and irregularly divided into small thin appressed brown scales tinged with red. Wood heavy, hard, close-grained, and light brown, with thick lighter colored sapwood. The bark is tonic and is sometimes used in decoctions and in the treatment of intermittent fevers, or as an aperient and diuretic, and in homœopathic practice.
Distribution. Banks of streams in rich moist soil; southeastern Pennsylvania to the Manitee River region, western Florida, and through the Gulf states to northern Arkansas (Baxter and Cleburne Counties), southwestern Oklahoma (near Page, Leflore County) and the valley of the Brazos River, Texas; ascending on the southern Appalachian Mountains to altitudes of 4000°.
