Herbs or shrubs. Leaves alternate or opposite, generally 

 without stipules. Sepals 4 or 5, more or less coherent with 

 each other and adnate to the ovary. Petals as many as the 

 sepals and alternate with them. Stamens as many as the 

 petals and alternate with them, or 2-10 times as many. Ovary 

 usually of 2 carpels, united only at the base or more or less 

 throughout. Fruit generally a 1-2-celled capsule, sometimes 

 a berry. Seeds many, with endosperm.

 ovary, its 5 lobes usually colored like the petals. Petals 5, 

 small, generally inserted on the throat of the calyx-tube. 

 Stamens 5, inserted with the petals. Styles 2. Ovary 1- 

 celled, with 2 placentae on its walls^ becoming in fruit a 

 pulpy (usually eatable) berry.
