Succulent herbs with exstipnlate leaves, Flowei-s perfectly s^-m- 

 metrical, cymosely arranged. Sepals 3—20, more or less united at base. 

 Petals as many, inserted in the bottom of the calyx, distinct or cohering 

 below to form a gamopetalous corolla. Stamens as many or twice as 

 many as the petals, when of the same number alternate with them ; 

 filaments distinct, subulate. Ovaries as many as the petals, opposite to 

 them, forming a whorl, each with or without a hypogynous scale at base. 

 Fruit follicular. Seeds attached to the margins of the suture, small, 

 albuminous.

 Sepals and petals 3-5, distinct or united at base. Stamens as many 

 Carpels distinct ; styles short-subulate. Follicles 1— several-seeded.
