valvate, often gland-dotted or -striate. Stamens opposite to the corolla- 

 lobes and equal to them in number, free or adnate to the lobes or in an 

 inner ring, generally erect ; filaments long or short ; anthers opening 

 by slits, usually introrsely, sometimes septate as in ^giceras and 

 Ardisia littoralis, sometimes with terminal openings as well, free or 

 adherent by their edges ; the connective often thickened and produced, 

 sometimes glandular; staminodes sometimes present, though not in 

 Malay species. Ovary globose, ovoid or oblong, free (in Mcesa adherent 

 to the calyx- tube), 1-celled, narrowed into or surmounted by the style; 

 style filiform or columnar, stigma usually simple ; ovules few or many, 

 inserted on or immersed in a free usually globose central placenta. 

 Fruit usually small, globose (in ^giceras linear, curved, acuminate) ; 

 epicarp fleshy, mesocarp crustaceous, endocarp membranous, separable; 

 usually one- rarely several-seeded (as in McBsa), indehiscent. Seeds 

 usually globose, hollowed at the base : in Mcesa many and angled ; 

 albumen pitted or ruminate ; embryo transverse, cylindric ; radicle 

 usually elongate. — Disteib. Tropical or sub-tropical regions of both
