much like those of our Meconopsis — have far fewer and coarser and 

 more quadrate i-eticulations than those of P. dubium. I conclude, 

 therefore, that Mr. Spence's plant is an indigenous species. I suspect 

 that it may not be so very rare and local, and that its close resem- 

 blance to our Meconopsis has allowed it to be overlooked. The habit 

 of the two is quite similar. So far as I have seen the foliage, I could 

 not certainly distinguish the two except by the sparse hairiness of the 

 true Poppy. This discovery suggests a probable genealogy of our 

 American Meconopsis.
