3. HYPELATE P. Br.
A glabrous tree or shrub, with smooth bark and slender terete branchlets. Leaves long-petioled, the petioles sometimes narrow-winged, 3-foliolate, the terminal leaflet rather larger than the others, persistent; leaflets sessile, obovate, rounded or rarely acute or emarginate at apex, entire, with thickened revolute margins and a prominent midrib, coriaceous, feather-veined, the veins arcuate and connected near the margins, dark green and lustrous on the upper surface, bright green on the lower surface. Flowers regular, polygamo-monœcious, minute, on slender pedicels from the axils of minute deciduous bracts, in few-flowered long-stemmed wide-branched terminal or axillary panicles; calyx 5-lobed, the lobes ovate, rounded at apex, slightly puberulous on the outer surface, ciliate on the margins, deciduous by a circumscissile line, petals 5, rather longer than the calyx-lobes, rounded, spreading, ciliate on the margins, white; stamens 7 or 8, inserted on the lobes of the annular fleshy disk; filaments filiform, as long as the petals in the staminate flower, much shorter in the pistillate flower; anthers oblong, attached on the back near the bottom, the cells spreading from above downward; ovary sessile on the disk, slightly 3-lobed, 3-celled, contracted into a short stout style, rudimentary in the staminate flower; stigma large, declinate, obscurely 3-lobed; ovules 2 in each cell, borne on the middle of its inner angle, superposed, amphitropous, the upper ascending, with the micropyle inferior, the lower pendulous, with the micropyle superior. Fruit an ovoid black drupe crowned with the remnants of the persistent style and supported on the persistent base of the disk; flesh thin and fleshy; walls of the stone thick and crustaceous. Seed solitary by the abortion of the upper ovule, suspended, obovoid; seed-coat thin, slightly wrinkled; embryo conduplicate, filling the cavity of the seed; cotyledons thin, foliaceous, irregularly folded, incumbent on the long radicle.
The genus with a single species is distributed from southern Florida to the Bahamas, Cuba, Porto Rico, St. Martin, Anguilla and Jamaica.
Hypelate is the ancient name of the Butcher’s Broom.
1. [Hypelate trifoliata] Sw. White Ironwood.
Leaves unfolding in June and persistent until their second season or longer; petioles stout, 1½′—2′ in length, with narrow green wings; leaflets 1½′—2′ long and ¾′—1¼′ wide. Flowers appearing in Florida in June, rather less than ⅛′ in diameter, in few-flowered panicles 3′—4′ long, on a slender peduncle, the staminate and pistillate in separate panicles on the same tree. Fruit ripening in September, ⅜′ long, with a sweet rather agreeable flavor.
A tree, sometimes 35°—40° high, with a trunk occasionally 18′—20′ in diameter, and branchlets pale green when they first appear, becoming gray during their first season and bright red-brown the following year; generally much smaller. Bark of the trunk rarely ⅛′ thick, marked by shallow depressions and numerous minute lenticels. Wood very heavy, hard, close-grained, rich dark brown, with thin darker colored sapwood of 4 or 5 layers of annual growth; very durable in contact with the soil and valued in Florida for posts; also used in shipbuilding and for the handles of tools.
Distribution. Southern Florida, Upper Metacombe, Umbrella and Windley’s Keys; rare.
