Herbs or shrubs, often glandular. Leaves alternate, entire, angled, or 

 digitately lobed. Flowers monoecious, in terminal cymes, the central flowers 

 of the cyme usually female. Male flowers with 5 imbricate sepals and 5 

 free or connate petals. Stamens usually 8 or 10, sometimes more; filaments 

 all connate, or outer ones free. Female flowers with calyx as in the males, 

 the petals often absent. Carpels connate in a 2- to 4-celled ovary; ovules 

 solitary; styles connate below, 2-fid above. Fruit a dehiscent capsule of 

 two to four 2-valved cocci. Seed ovoid or oblong, albumen fleshy. (Greek
