20 FUMARIACE.E. 



angular pod, Hairy Platystigraa. The exceedingly prickly Bristly Argemone is repre- 

 sented on the right, below, by a bud and a couple of bracts. A pistil with its whit^ 

 prickles is imperfectly shown against one of the bracts. 



The Order Papaveracese is characterized by flowers with 2 or 3 caducous sepals, 

 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 of the petals. 



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

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

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

 Eschscholtzia and Platystemon are the most widely distributed of the California 

 genera. Key to genera and species, p. 83. 



PAP AVER and MECONOPSIS. 



Our species of Meeonopsis is put by Greene with the true poppies in the genus 

 Papaver. He thinks with Bentham that the small erect flowering form is a separate 

 species, viz: P. crassifolium. 



Two more species of Papaver may be added. 



P. Californicum, Gray. 1-2^ feet high; leafy below: peduncles long: corolla 2 

 inches broad, brick red with green spots at the base: stigmas sessile and radiating. 



P. liemmoni, Greene. Larger: stigmas 7-10, their lower half sessile and radiant 

 upon the pod, the upper half coherent and forming a conical apiculation. 



PLATYSTEMON, PLATYSTIGMA and ESCHSCHOLTZIA. 



Prof. Greene unites the genus Platystigma with Platystemon and adds a new 

 species. 



P. Torreyi, Greene. Glabrous: the three carpels united to form a slender, twisted 

 pod. 



Botanists will probably never agree about the number of species of Eschscholtzia. 



Tender herbs with dissected compound leaves, and irregular hypogynous flowers, the 

 parts in twos, except the 6 diadelphous stamens.
