Description
|
Usually fleshy or succulent herbs or subshrubs, with thick stems and alternate (infrequently opposite), many-ranked leaves. Leaves usually thick and fleshy, mostly simple and entire or crenulate, infrequently pinnately compound, in many species living for a considerable time after being removed from the plant and in some cases capable of producing plantlets from the marginal indentations. In- florescence frequently cymose, less often racemose or paniculate. Flowers typically coarse and stiff, perfect, regular, polypetalous or sympetalous; calyx 4- to 5-parted, the sepals free or united; petals 4-5, free or united, mostly persistent; stamens in 1 or 2 cycles, each cycle isomerous with the petals; carpels as many as-the petals or sepals, essentially free or united at the base, the ovules usually numerous from a ventral placenta; receptacle normally with a scale opposite each carpel. Fruit follicular from the individual carpels; seeds small, punctulate.

Note
|
A family represented in almost all parts of the world, especially in Africa; best represented in warmer latitudes, not uncommonly under subalpine conditions. A. Berger (in Engl. & Prantl, Nat. Pflanzenfam. 18a:3 52-483. 1930) probably has given the most acceptable recent treatment of the family.
