1. CYRILLA L.
A glabrous tree or shrub, with spongy bark, slender terete branchlets conspicuously marked by large leaf-scars, and narrow acute winter-buds covered with chestnut-brown scales. Leaves usually clustered near the end of the branches, oblong or oblong-obovate, pointed, rounded, or slightly emarginate at apex, conspicuously reticulate-veined, short-petiolate. Flowers on pedicels from the axils of narrow alternate persistent bracts, in slender racemes from the axils of fallen leaves or of small deciduous bracts near the end of the branches of the previous year; calyx minute, divided nearly to the base into 5 ovate-lanceolate acute coriaceous lobes; petals 5, contorted in the bud, white or rose color, inserted on an annular disk, three or four times longer than the calyx-lobes, oblong-lanceolate, acute, concave, subcoriaceous, furnished below the middle on the inner surface with a broad glandular nectary; stamens 5, opposite the divisions of the calyx, inserted with and shorter than the petals; filaments subulate, fleshy; anther-cells united above the point of attachment, free below; ovary ovoid, free, sessile, pointed, 2-celled; styles short, thick; stigma 2-lobed, with spreading lobes; ovules 3 in each cell, suspended from an elongated placental process developed from the apex of the cell. Fruit 2-celled, broad-ovoid, crowned with the remnants of the persistent style; pericarp spongy. Seeds 2 in each cell, elongated, acuminate; embryo minute, cylindric, 2-lobed.
Cyrilla is represented by a single species of the coast region of the south Atlantic and Gulf states and of the Antilles and eastern tropical South America.
The name commemorates the scientific labors of Dominico Cirillo (1734—1799), the distinguished Italian naturalist and patriot.
1. [Cyrilla racemiflora] L. Ironwood. Leather Wood.
Leaves 2′—3′ long and ¼′—1′ wide, with a stout petiole ⅛′—1′ in length; turning late in the autumn and early winter to brilliant shades of orange and scarlet and then deciduous, or southward persistent with little change of color until the beginning of the following summer. Flowers appearing late in June or early in July, in racemes usually 6—10 together and 4′—6′ long, at first erect, becoming pendulous before the fruit ripens. Fruit ripening in August and September, rarely more than 1/16′ long; seeds light brown.
A slender tree, occasionally 30°—35° high, with a stout often eccentric trunk 10′—14′ in diameter, dividing several feet above the ground into numerous wide-spreading branches, and slender branchlets bright brown during their first season and ultimately ashy gray; often a broad bush sending up many slender stems 15°—20° high. Winter-buds about ⅛′ long. Bark of the trunk rarely more than ½′ thick except near the base of old trees, and covered by large thin bright red-brown scales. Wood heavy, hard, close-grained, not strong, brown tinged with red, with rather lighter colored sapwood. The spongy bark at the base of the trunk is pliable, absorbent, and astringent, and has been recommended as a styptic.
Distribution. Rich shaded river-bottoms, the borders of sandy swamps and shallow ponds of the coast Pine-belt, or on high sandy exposed ridges rising above streams near the Gulf coast; southeastern Virginia southward near the coast to northern Florida and westward along the Gulf coast to the valley of the Neches River, Texas; in Lake County, Florida, and ranging northward in Mississippi to Forrest County (near Hattiesburg, T. G. Harbison), and in Alabama to Dallas County; in swamps near the coast of western Florida often a low shrub with smaller leaves and shorter racemes (var. parviflora Sarg.); in Cuba, Jamaica, Porto Rico, Demarara, and Brazil (var. racemifera Sarg.).
