Sepals 5. Petals 5, rarely reduced to 4 or 3. Stamens usually 10, outer 

 ones in a single series all round tlie carpels, either aU perfect, or 2 or 3 of 

 them reduced to small staminodia ; filaments either thickened and ovoid, or 

 flat, short, and broad ; anthers erect ; two inner staminodia alternating witli 

 the carpels, and similar to the perfect stamens, except that the anthers are 

 small and empty or wanting. Carpels 2, 2-ovulate. Styles and fruit of
