Erect or procumbent shrub, 0.15—2 meters high, much branched, the branches stout, 
terete, dark-gray to whitish, resinous, densely white-pilose or sericeous or glabrate; stipules 
4 mm. long or shorter, densely imbricate, subtruncate to acute, mucronate, brown, sericeous or 
glabrate outside, densely white-ciliate, sometimes resinous; leaves 2-8 mm. long, linear-oblong 
to ovate, obtuse or acute at the apex, thick-coriaceous, often as thick as broad, lustrous, green or 
brownish, sulcate beneath along the costa: hypanthium at anthesis about 1 mm. long, glabrous; 
calyx-lobes several times as long as the hypanthium, brownish, attenuate, glabrous but densely 
ciliate with long white hairs, in fruit much exceeding the capsule; corolla 8-10 mm. long, the 
tube slender, densely sericeous above, glabrate below, the lobes one fourth as long as the tube 
or shorter, oblong or oval, obtuse or rounded at the apex, sericeous outside, glabrous within; 
capsule 3 mm. long and nearly as broad, subcompressed, sulcate, rounded or subretuse at the 
apex, the free portion densely white-pilose; seeds very irregular, 1 mm. long or smaller, brown. 
TYPE LOCALITY: [Coastal cliffs near Havana, Cuba!. 
DISTRIBUTION: On rocks along the coast, Bahamas, Cuba, Isle of Pines, Jamaica, and Yucatan.

Shrubs or trees, glabrous or pubescent; branches terete. Stipules interpetiolar, triangular, 
acute, persistent. Leaves opposite, short-petiolate, the blades coriaceous. Flowers solitary 
in the axils of the leaves, or in axillary racemes or panicles; bractlets 2, minute; hypanthium 
narrowly oblong; calyx with a distinct tube, 4-lobate, the lobes open in bud, obtuse, equal 
or unequal; corolla salverform, glabrous within, the tube cylindric, scarcely ampliate above, 
the throat annular-thickened, the 4 lobes imbricate, ovate, fleshy, spreading or recurved. 
Stamens 4, inserted in the corolla-throat; filaments very stout; anthers dorsifixed, oblong- 
linear, obtuse, included. Style filiform, glabrous, bilobate. Disk annular, pilose. Ovary 
oblong, compressed, 2-celled, costate; ovules few in each cell (2-6), the placentae peltate. 
Capsule oblong-linear or elliptic, the exocarp thin, crustaceous, the endocarp subosseous, at 
first septicidally dehiscent, the valves finally deeply bipartite. Seeds few, lance-linear, the 
testa lineolate, produced at each end; endosperm fleshy; embryo linear; cotyledons linear, 
obtuse, the radicle terete.
