Gymnanthes with about ten species is confined to the tropics of the New World and is distributed from southern Florida, where one species occurs, through the West Indies to Mexico and Brazil.
The generic name, from γυμνός and ἄνθος, relates to the structure of the naked flowers.
1. [Gymnanthes lucida] Sw. Crab Wood.
Leaves oblong-ovate or ovate-lanceolate, obscurely and remotely crenulate-serrate or often entire, when they unfold thin and membranaceous, deeply tinged with red, and glandular on the teeth with minute caducous dark glands, and at maturity coriaceous, dark green and lustrous on the upper surface and pale and dull on the lower surface, 2′—3′ long, ⅔′—1½′ wide, with a broad pale midrib raised and rounded on the upper side, obscure primary veins arcuate and united near the margins and connected by prominent coarsely reticulate veinlets; appearing in Florida in early spring and remaining on the branches through their second summer; petioles broad, slightly grooved, about ¼′ in length; stipules ovate, acute, light brown, clothed on the margins with long pale hairs, about 1/16′ long. Flowers: inflorescence buds appearing in Florida late in the autumn in the axils of leaves of the year and beginning to lengthen in spring, the inflorescence becoming 1½′—2′ long, with a slender glabrous angled rachis, the scales broad-ovate, pointed, concave, rounded and thickened at apex, puberulous and ciliate on the margins, those inclosing the male flowers connate with the flowers and persistent under the calyx, those subtending the female flowers at the base of the inflorescence and not raised on their peduncle. Fruit produced in Florida sparingly, ripening in the autumn, slightly obovoid, dark reddish brown or nearly black, ⅓′ in diameter, covered with thin dry flesh, and pendent on a slender stem 1′ or more in length; seeds ovoid.
A tree, occasionally 20°—30° high, with a trunk 6′—8′ in diameter and often irregularly ridged, the rounded ridges spreading near the surface of the ground into broad buttresses, slender erect branches forming a narrow open oblong head, and slender upright branchlets light green more or less deeply shaded with red when they first appear, becoming in their first winter light gray-brown faintly tinged with red and roughened by numerous oblong pale lenticels, ultimately ashy gray and marked at the end of their second year by the semiorbicular elevated leaf-scars displaying the ends of 4 fibro-vascular bundle-scars superposed in pairs. Winter-buds ovoid, obtuse, covered with chestnut-brown scales, about 1/16′ long. Bark of the trunk dark red-brown, about 1/16′ thick, separating into large thin scales, in falling displaying the light brown inner bark. Wood very heavy, hard, close-grained, rich dark brown streaked with yellow, with thick bright yellow sapwood; in Florida occasionally manufactured into canes, and used as fuel.
Distribution. Florida, common in low woods from the shores of Bay Biscayne to the Everglade Keys, Dade County, and on many of the southern keys to those of the Marquesas group; on the Bahama Islands, and on many of the Antilles.
XXXI. ANACARDIACEÆ.
Trees or shrubs, with terete pithy branchlets, resinous juice, and alternate simple or pinnate leaves, without stipules, and scaly or naked buds. Flowers regular, minute, diœcious, polygamo-diœcious, or polygamo-monœcious; calyx-lobes and petals 5, imbricated in the bud or 0; stamens as many as the petals and alternate and inserted with them on the margin or under an hypogynous annular fleshy slightly 5-lobed disk; filaments filiform; anthers oblong, introrse, 2-celled, the cells opening longitudinally; ovary 1-celled; styles 1—3; ovule solitary, suspended from the apex of a slender funicle rising from the base of the cell, anatropous; micropyle superior; styles 3, united or spreading; stigmas terminal. Fruit drupaceous. Seed without albumen; seed-coat thin and membranaceous; embryo filling the cavity of the seed; cotyledons flat, accumbent on the short radicle.
The Sumach family with some sixty genera is mostly confined to the warmer parts of the earth’s surface and contains the Mango, Pistacia, and other important trees. In the flora of the United States four genera have arborescent representatives.
