PAPAVERACEAE 13 



in some of our cultivated grounds ; and if not attended to, may be- 

 come a troublesome weed. The P. somntferum, L, the sleep- 

 bringing, or Opium Poppy, is to be seen in almost every garden, 

 and nearly naturalized. Dr. DARWIN thus notices it, in his gorgeous 

 poem: 



" Sopha'd on silk, amid her charm-built towers, 

 Her meads of asphodel, and amaranth bowers, 

 Where Sleep and Silence guard the soft abodes, 

 In sullen apathy PAPAVEE nods."
