to their inner edges, as is normally the case. A capsule 

 is calculated to contain 32.000 seeds. An oil is obtained 

 from the seeds, used sometimes to adulterate olive oil. 

 Observe also the floral receptacle of the Californian 

 genus, Eschscholtzia, a common garden annual, with 

 orange flowers ; the receptacle grows up around the lower 

 part of the ovary, without becoming adnate to it, forming 

 a sheath to its base. The stamens and envelopes of the 

 flower are carried up with it, and consequently become 

 perigynous. 



Compare the relation of the rays of the stigma to the 

 divisions of the ovary in the Poppy and the Water-lily. 

 In the former the pistil is essentially syncarpous, and the 

 carpels are 'coherent throughout, so that each ray of the 

 stigma is immediately above, and opposite to, the partial 

 dissepiments, and, like the dissepiments, double.
