 Stamens eight to twenty-four, or numerous. Fruit one-celled, with 

 two to five or numerous parietal placenta?, from which the valves 

 often separate in dehiscence. Seeds numerous, with a minute em- 

 bryo, and copious fleshy and oily albumen. — Ex. The Poppy (Pa- 

 paver), the leading representative of this small but important family, 

 is remarkable for the extension of the placenta? so as almost to divide 



the cavity of the ovary into several cells, and for the dehiscence of 

 the capsule by mere chinks or pores under the edge of the crown
