A tree, sometimes 20°—25° high, with a trunk rarely more than 6′ in diameter, and branchlets becoming terete during their third season and covered with thin slightly grooved roughened bright red-brown bark. Bark of the trunk thin, brown tinged with red, separating into thin minute scales. Wood very heavy, hard, close-grained, dark brown or nearly black, with thick light brown sapwood of 75—80 layers of annual growth.
Distribution. Florida, common and generally distributed over the southern keys from the Marquesas group to Upper Matecombe Key; in Cuba, Porto Rico, Trinidad, and southern Mexico. A form (var. glaucescens, Small.) with smaller less coriaceous very glaucous leaves occurs in Cuba.
5. SCHÆFFERIA Jacq.
Glabrous trees or shrubs, with slender rigid terete branches and small obtuse buds. Leaves alternate, or fascicled on short spur-like branchlets, entire, obovate or spatulate, acute and minutely apiculate or gradually narrowed to the rounded or emarginate apex, cuneate below, persistent, without stipules. Flowers diœcious, pedicellate in axillary clusters from buds covered by scale-like persistent bracts; calyx 4-lobed, the lobes orbicular, persistent, much shorter than the 4 hypogynous, oblong, obtuse, white or greenish white petals; stamens 4, hypogynous, inserted under the margin of the small inconspicuous disk opposite the lobes of the calyx, wanting in the pistillate flower; filaments subulate, incurved; anthers oblong-ovoid; ovary 2-celled, ovoid, sessile, free, rudimentary in the staminate flower; style very short, gradually enlarged into the large 2-lobed stigma, with spreading lobes; ovule solitary, ascending; raphe thin, ventral; micropyle inferior. Fruit a small 2-seeded fleshy drupe, ovoid or obovoid, crowned with the remnants of the persistent style, indistinctly 2-lobed by longitudinal grooves, slightly flattened; flesh thin and tuberculate; nutlets 2, obovoid, rounded at the ends, with a thick bony shell. Seed solitary, ascending; seed-coat membranaceous; albumen fleshy; cotyledons broad, foliaceous; radicle very short, inferior, next the hilum.
Schæfferia with four or five species is confined to the New World, with one species in southern Florida, and another, a small shrub, Schæfferia cuneifolia A. Gray in the arid region of western Texas and northern Mexico.
The generic name is in honor of Jakob Christian Schaeffer (1718—1790), the distinguished German naturalist.
1. [Schæfferia frutescens] Jacq. Yellow Wood. Box Wood.
Leaves bright yellow-green, 2′—2½′ long, ½′-1′ wide, with thick revolute margins, appearing in Florida in April and persistent on the branches until the spring of the following year; petioles short and broad. Flowers opening in spring on branchlets of the year, ⅛′ across, the staminate generally 3 or 5 together on pedicels rarely more than ⅙′ long, the pistillato solitary or 2 or 3 together on pedicels rather longer than the petioles. Fruit ripening in Florida in November, slightly grooved, compressed, bright scarlet, with an acrid disagreeable flavor.
A glabrous tree, 35°—40° high, with a trunk sometimes 8′—10′ in diameter, erect branches, and slender many-angled branchlets pale greenish yellow during their first season, becoming light gray during their second year and then conspicuously marked by the remains of the persistent wart-like clusters of bud-scales; or often a tall or low shrub. Bark of the trunk rarely more than 1/12′ thick, pale brown faintly tinged with red, the surface divided by long shallow fissures, and ultimately separating into long narrow scales. Wood heavy, close-grained, bright clear yellow, with thick rather lighter colored sapwood; sometimes used as a substitute for boxwood in wood engraving.
