Evergreen shrub to small tree to 4 m tall; twigs
± moderately angled, slender, sparsely lepidote, otherwise sparsely
to densely pubescent; buds ovoid, 1-2 x 0.7-1.3 mm. Leaf blades elliptic
to ovate, 2-8 x 0.9-4.2 cm, ± flat to slightly abaxially curved,
coriaceous, ca. 0.3-0.47 mm thick; base cuneate to rounded; apex acuminate,
to acute, rounded, or truncate; margin plane to slightly revolute, the
apical portion obscurely and irregularly toothed to entire, the basal portion
entire to sinuous; venation brochidodromous, 3o veins ± reticulate;
adaxial surface lepidote but scales usually quickly deciduous, sparsely
to densely pubescent on midvein, especially basal portion, the 3o and higher
order veins usually visible, the 2o veins visible, usually not depressed;
abaxial surface moderately lepidote, otherwise glabrous to densely pubescent,
but usually at least some leaves of shoot with unicellular hairs, the 3o
and higher order veins obscure to very slightly raised, not forming dense,
fine, raised network, the 2o obscure to slightly raised and visible; scales
rust colored, persistent to deciduous, ca. 0.1-0.25 mm in diameter, erose
to entire; petiole 3-10 mm long, lepidote, otherwise pubescent adaxially
or all around; flower buds ± intermixed with vegetative buds.
Inflorescences fasciculate, 4- to 15-flowered; pedicels clearly articulated
with calyx, slender, 4-8.5 mm long, lepidote, otherwise sparsely to densely
pubescent; bracts ± opposite, basal or nearly so, narrowly triangular,
0.7-1.6 mm long; floral bracts to ca. 2 mm long. Flowers 5- or 6-merous;
calyx lobes triangular, with acuminate apices, 1-2 x 0.7-1.5 mm, adaxial
side glabrous or sparsely pubescent, especially near apex, abaxial side
lepidote, otherwise glabrous to sparsely pubescent; corolla cylindrical,
white (pink tinged toward mouth), 5-8 x 3.5-5 mm, abaxially sparsely lepidote;
filaments roughened, 3-5 mm long, unappendaged or with very small spurs
near anther-filament junction; anthers 1-1.8 mm long; ovary lepidote, otherwise
pubescent, placentae ± subapical. Capsules ellipsoid to ovoid,
4-6.5 x 3.5-6 mm, slightly lepidote, otherwise sparsely pubescent, especially
near base, the pale, very thick sutures separating as unit from adjacent
valves; seeds 1.5-3 mm long.
Distribution. Endemic to St. Thomas, in thickets/scrub
forest(?), at ca. 250-300 m. Flowering December through March.
