2. FORESTIERA Poir. Swamp Privet.
Adelia Michx.
Trees or shrubs, with thin close bark, slender branchlets, and small scaly buds. Leaves simple, entire or serrulate, petiolate, deciduous or persistent. Flowers diœcious or polygamous, minute, on slender ebracteolate pedicels, in fascicles or panicles, their bracts caducous, from buds in the axils of leaves of the previous year and covered with numerous scales; calyx reduced to a narrow ring or cup-shaped, 5 or 6-lobed; corolla 0; stamens hypogynous; filaments 2—4; anthers ovoid, opening by lateral slits; ovary 2-celled, gradually narrowed into a slender style terminating in an abruptly enlarged 2-lobed stigma; ovules 2 in each cell, suspended from its apex; raphe dorsal. Fruit 1 or very rarely 2-celled, drupaceous, oblong or subglobose, with thin flesh and a thin-walled stone; seed 1 in each cell, pendulous, testa membranaceous; albumen fleshy; cotyledons plane, nearly filling the cavity of the stone.
Forestiera with 14 species is distributed from the southern United States and Mexico through Central America to Paraguay, and through the West Indies to Brazil.
The generic name is in memory of the French physician and botanist Charles Leforestière.
1. [Forestiera acuminata] Poir.
Leaves elliptic, acuminate and long-pointed at apex, gradually narrowed and cuneate at base, serrate above the middle with small remote incurved teeth, glabrous with the exception of occasional hairs on the upper side of the slender midrib, yellow-green on the upper surface, paler on the lower surface, 2½′—4½′ long and 1′—1½′ wide, with usually 5 or 6 pairs of slender primary veins and slightly thickened and incurved margins, deciduous; petioles slender, often slightly winged above the middle, ¼′—½′ in length. Flowers appearing in April and May before the leaves from ovoid pointed buds ⅛′ long, with thickened pale chestnut-brown scales; calyx reduced to a narrow slightly lobed ring; corolla 0; staminate in many-flowered fascicles, on short pedicels from the axils of broad-obovate thin yellow apiculate conspicuous bracts; stamens 4, on long slender filaments; anthers bright yellow; ovary reduced to a minute ovoid body; pistillate flowers on slender pedicels ⅛′ long, in glabrous pedunculate several-flowered panicles ¾′—1¼′ long, their bracts caducous; stamens with shorter filaments and abortive or rarely fertile anthers, or usually 0; ovary oblong-ovoid, slightly unsymmetric, gradually narrowed into the long slender style enlarged into the thickened imperfectly 2-lobed terminal stigma. Fruit falling as soon as ripe in June and July, oblong-ovoid, gradually narrowed, acute and tipped with the remnants of the style at apex, gradually narrowed and rounded at base, slightly compressed and unsymmetric, dark blue-purple, 1′—1¼′ long, about ¼′ thick, with thin dry flesh, and a striate stone rounded at base, straight on one side and rounded on the other, its wall covered with thin vertical scales spongy in appearance, and conspicuously longitudinally ridged on the inner surface the ridges terminating in long slender tips forming the acuminate apex of the stone; seeds ellipsoid, slightly compressed, striate, light brown, about ⅓′ in length.
A tree, rarely 50° high, with a short trunk 8′—10′ in diameter, small spreading branches, and slender light brown branchlets becoming darker in their second year, and marked by numerous lenticels and by the small elevated nearly orbicular leaf-scars. Winter-buds: terminal ovoid, pointed, about 1/16′ long, with numerous scales increasing in size from the outer to the inner ranks; usually much smaller, and generally a shrub 10°—15° high and broad. Bark close, slightly ridged, dark brown.
Distribution. Borders of streams and swamps in low moist soil; valley of the lower Wabash River, southwestern Indiana, southern Illinois northward along the Mississippi River to Pike County, and to central Tennessee, and from southern Missouri through Arkansas to eastern Oklahoma (near Muskogee, Muskogee County) and eastern Texas to the valley of the lower Colorado River inland to Colorado County (shores of Eagle Lake), and through Louisiana, central and southern Mississippi and Alabama to western Florida (Branford, Suwanee County) and on the Savannah River, near Augusta, Richmond County, Georgia; most abundant in Missouri, Arkansas and Texas; comparatively rare east of the Mississippi River, but probably of its largest size in eastern Louisiana.
