This well-known genus of plants requires no very scientific 
description, for even those who have not thought much 
about plants are familiar with the form of the common 
species, 
Papaver Rumas, Red Poppy, which is a great ornament 
im our corn-fields, though I believe the farmer would rather 
dispense with its bright beauties. The petals are broad, 
deep scarlet, often black at the base, stem many-flowered, 
leaves divided, seed-vessel nearly globular. 
PapaveR bDuBIUM, Long smooth-headed Poppy, has a 
paler flower than the last, and an oblong seed-vessel. 
PAPAVER ARGEMONE, Long prickly-headed Poppy, has 
small flowers, petals narrow, and scarlet. Seed-vessel hairy 
and ribbed.
