Flora of the Malayan Peninsula. 
corymbs or fascicles, braeteolate or not, never involucrate (in the 
Malayan species). Calyx-tube short ; the limb persistent in part 
or deciduous. Corolla-tube straight, short ; the throat naked or hairy ; 
the lobes of the mouth 5, rarely 4 to 6, valvate in bud. Stamens as 
many as the corolla-lobes, inserted on the throat or mouth ; anthers 
linear or obtuse, attached dorsally near the base to short or long 
filaments. Ovary 2-celled ; style long or short, bifid ; ovules often 
cuneiform, solitary, erect from the base of each cell. Fruit small, 
baccate or drupe-like, ovoid globose or oblong, smooth or ridged, 
composed of two plano-convex, 1-celled, 1-seeded pyrenes ; or didymous 
and separating into two cocci. Seeds plano-convex, the ventral surface 
grooved or plane, the dorsal smooth, ridged or suleate ; testa thin, 
albumen hard ; embryo small, basal ; cotyledons broad, thin ; radicle 
inferior. — D istbib. Species about 550 ; tropical or sub-tropical.
