twice as many free petals in two sets, indefinite, usually numerous, free stamens, and a 

 compound pistil. In Eschscholtzia the sepals are united, and the stamens adhere to the 

 claws ot the petals. 



This small but interesting order of plants, with the exception of one species, is con- 

 lined to the northern hemisphere. Fifteen species, belonging to eleven genera, are natives 

 of the United States, and several European species have become naturalized. Esch- 

 scholtzia and Platystemon are the most widely distributed of the California genera. 



Rovineya CoulUri is a lialf shrubby plant, witli smooth pinnatifid leaves and very large white flowers 

 (3, i, or even 6 inches across) , a native of the coast from San Diego to Santa Barbara County. 



Arctomecon is another white-flowered plant, with somewhat hairy, nearly entire leaves; the petals 

 persistent; found in south Nevada and Utah. 



Canbya, a recently discovered plant of south-east California, is the smallest of the order, being 

 scarcely an inch in height. The small white petals are persistent. 



Fapaver Somniferum, a native of Asia, furnishes opium, which is the dried juice of the plant. A 

 variety of this species is cultivated in this State for the seeds, from which is expressed poppy oil, used 

 by artists. This oil is also used as a substitute for olive oil in the preparation of salads, etc.
