ILLUSTEATIONS OF THE NATURAL ORDERS. 



Darlingtonia, Torr., recently discovered in California, with calyx and 

 corolla not very unlike those of Sarracenia, but without the umbrella- 

 like style. The species of Sarracenia are all Eastern North Amer- 

 ican. The affinities of the group are unsettled. 



752. Ol'd, Papaveraceffi (Popp?/ Family/). Herbs with a milky or 

 colored juice, and alternate leaves without stipules. Calyx of two 

 (rarely three) caducous sepals. Corolla of four to six regular petals. 

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

 two to five or numerous parietal placentas, from which the valves 

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

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

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

 is remarkable for the extension of the placentas 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 



FIG, 688. Sanguinaria Canadensis (the Bloodroot). 689 The pod, divided transrersely, 

 showing the parietal attachment of the seeds 690 Longitudinal section of a magnified seed 

 Tvith its large rhaphe, showing the minute embryo, near the extremity of the albumen. 

 €91. Flower-bud of Eschscholtzia. 692. The calyptriform calyx detached from the base. 693.
