Sepals commonly 5, more or less united at the base, usually turgid. Petals 

 distinct, mostly spreading. Stamens twice the number of the peials. Car- 

 pels as many as the sepals, many-seeded, with an entire scale at the base of 

 each. — Herbs or rarely sufTrutescent plants, mostly branching from the base. 

 Leaves alternate or scattered, sometimes opposite or verticillate, usually 

 crowded on the sterile branches. Flowers cymose, sometimes with 4 or 6-7 

 sepals and petals, and consequently 8 or 12-14 stamens.
