Perennial, herbaceous plants, with radical, petiolate leaves, and 

 with usually terminal, clustered, regular, and perfect flowers. Se- 

 pals five, rarely four, equal, and more or less united at the base, 

 persistent. Petals five, rarely four, caducous or withering, im- 

 bricated in prefloration. Stamens as many as the petals or twice 

 as inany, free. Anthers extrorse, opening by two slits or two 

 terminal pores. Ovary free, 1 -celled, with parietal, rarely basal, 

 placentas, or 2-3-celled, with angular placentas. Ovules nume- 

 rous, horizontal or ascending. Styles as many as the placentas 

 or as the cells. Stigmas capitate. Fruit capsular, either 1 -celled 

 and 3-5-valved or 2-3-celled, with loculicidal dehiscence (that is, 

 when the entire carpels composing the fruit separate, carrying 

 the seeds and placentas along with them), rarely with septicidal 

 dehiscence (when the capsule or carpels open through the rup- 

 ture of the partitions, septa). Seeds horizontal, ascending or 

 pendulous, with a lax, reticulate testa, which is rarely tight.
