        Evergreen, erect shrub to moderate-sized tree to 7(-10) m tall, with brownish to gray, longitudinally furrowed bark; twigs moderately ridged, slender, sparsely lepidote, otherwise densely to sparsely pubescent; buds ovoid, 0.6-2.5 x 0.5-1.5 mm.  Leaf blades elliptic to slightly ovate or obovate, 2.5-8.5(-11) x 1-3(-5.5) cm, ± flat, coriaceous, ca. 0.27-0.34 mm thick; base narrowly cuneate to rounded; apex acute to acuminate, rounded, or truncate; margin plane to slightly revolute, apical portion entire to very obscurely toothed, basal portion entire; venation brochidodromous, 3o veins ± reticulate; adaxial surface lepidote but scales usually quickly deciduous, densely pubescent on midvein, especially basal portion, 3o and higher order veins faintly visible, 2o veins visible but usually not depressed; abaxial surface moderately lepidote, otherwise glabrous, the 3o and higher order veins ± flat or nearly so, often laxly reticulate, the 2o veins slightly raised to occasionally obscure; scales rust colored, becoming whitish with age, persistent, ca. 0.09-0.25 mm in diameter, erose to nearly entire; petiole 3-14 mm long, lepidote, otherwise pubescent adaxially or all around; flower buds above or intermixed with vegetative buds.  Inflorescences fasciculate, ca. 5- to 15-flowered; pedicels clearly articulated with calyx, slender, 4-11 mm long, lepidote, otherwise glabrous to sparsely pubescent; bracteoles opposite to subopposite, basal or nearly so, narrowly triangular, 0.8-1.4 mm long; floral bracts to ca. 2.5 mm long.  Flowers (4-) 5- (6-)merous; calyx lobes triangular, with acuminate apices, 1-2 x 0.6-1.3 mm, abaxial side sparsely pubescent, especially near apex, abaxial side lepidote, otherwise glabrous (sparsely pubescent near junction with pedicel); corolla cylindrical to less commonly long-urceolate, white, (4-)4.5-7 x (2-)2.5-4.5 mm, abaxially sparsely lepidote; filaments roughened, 3-4 mm long, essentially unappendaged; anthers 0.8-1.1 mm long; ovary lepidote, otherwise pubescent, placentae ± subapical.  Capsules ellipsoid to ovoid, 4-6(-7) x 3-4 mm, slightly lepidote, otherwise sparsely to moderately pubescent, especially near base, the pale, very thick sutures separating as unit from adjacent valves; seeds 2-3 mm long.

        Distribution.  Endemic to Jamaica (chiefly S slopes of Blue Mountains), in dry forests and thickets, at (150-)300-1300 m elev.  Flowering chiefly late May through early August.
