filiform style, this stigmatose on the inner side. Anthocarp woody, longitudinally costate. 
Seed with a membranaceous testa adherent to the pericarp; embryo straight, the cotyledons 
cordate, enclosing the scanty endosperm, the radicle inferior. :

Shrubs or trees, unarmed, glabrous or pubescent. Leaves mostly opposite, usually 
petiolate, the blades entire, often thick-coriaceous. Flowers dicecious, small, reddish, yellow-

5-dentate, the teeth short, induplicate-valvate. Stamens 6-10, exserted, the filaments un- 
equal, filiform, short-connate at the base, the anthers oblong. Pistillate perianth tubular, 
the limb narrow, shallowly 5-dentate. Ovary elongate-ovoid, sessile, attenuate to the usually 
short-exserted style, the stigma penicillate. Anthocarp drupaceous, the exocarp fleshy, juicy, 
red to black, the utricle elongate, papyraceous or coriaceous, striate. Seed with a hyaline 
testa adherent to the pericarp; embryo straight, the cotyledons broad, enclosing the scanty 
endosperm, the radicle short, inferior.
