 the stipules absent; flowers bisexual, polygamous or unisexual, solitary or in cymes, acrinomorphic; sepals 4 or 5, imbricate; 

 petals 4 or 5, imbricate or contorted; stamens usually many, rarely few, connate in fascicles; ovary superior, 3- to 5-locular or 

 1-locular; styles as many as the carpels, free or connate; ovules usually many, on parietal placentas; fruit a capsule or drupe, 



sometimes berrylike; seeds without endosperm. ^More than 45 genera, with about 650 species, chiefly in the Tropics, a few 



genera in temperate regions.
