to the base of the corolla (in Diplycosia sometimes epigynous) ; filaments free ; 
anthers oblong, opening by pores or slits at the apex (in Diplarche by longi- 
tudinal slits), the cells often produced upwards into tubes, sometimes dorsally 
spurred. Ovary 5- (or 4-16-)celled ; style cylindric ; stigma simple or shortly 
obed; ovules many in the inner angles of the cells, or placenta often pen- 
dulous from the upper angle, Fruit capsular, loculicidally or septicidally 
5-valved; in Gaultheria and Diplycosia enclosed by the enlarged succulent 
calyx, appearing baccate. Seeds many (rarely few) in each cell, albuminous; 
testa close or loose or produced.—Species 1000, in all parts of the globe.
