Calyx small, eglandular within; sepals 5, almost free, imbricate, 
usually broad and obtuse, sometimes unequal or partly or wholly 
suppressed, Corolla salver-shaped; tube cylindric, slender, slightly 
widened at the base, without appendages in the mouth ; lobes 5, broad, 
oblong, overlapping to the left, straight or more or less twisted. 
Stamens in the widened base of the corolla-tube ; anthers free from the 
stigma, oblong, apiculate, 2-lobed at the base ; anther-cells polliniferous 
and dehiscent to the base. Disc 0. Ovary apocarpous, semi-inferior ; 
carpels 2; style very short, columnar; stigma just below the anthers, 
ellipsoid, copiously viscous in the lower part, somewhat constricted 
above, with a thick papillose ring below the 2-fid, stout apicuius ; 
ovules numerous, pluriseriate. Mericarps follicular, divaricate, elliptic 
to linear in outline, coriaceous. Seeds oblong or lanceolate, flattened, 
winged at the apex or all round; endosperm fleshy, thin ; cotyledons 
oblong or ovate-cordate ; radicle short.—T'rees or tall shrubs, usually

secondary nerves numerous, straight, connected by a more or less 
conspicuous marginal nerve; axillary stipules 0; petiole resinous at 
the base, without external glands. Flowers rather large, white or 
pink, frequently with a yellow centre or quite yellow, in contracted or 
ultimately elongate cymes arranged in terminal, often umbelliform 
corymbs or panicles, and supported by often large, caducous bracts. 
Species 30-40, natives of tropical America; some of them naturalised or com- 
only cultivated in the tropics of the Old World.
