POPPY FAMILY. Papaveraceae. 



alights on the flower, forces its head between the innei 

 petals, and gathers only the pollen with its front feet ! 

 Such a pendulous position as the flower compels is ex- 

 tremely difficult for insects other than bees to maintain. 

 Butterflies therefore visit the flower with less success 

 than bumblebees. Pierisrapce (Cabbage butterfly, white), 

 Papilio ajax (buff and black, crimson spots), and Danais 

 archippus (the Monarch, black-and-tan) are common 

 visitors ; so are the little long-tongued flies of the tribe 

 Bombylias (the beelike flies). Flowering stem 5-9 inches 

 high. In thin woodlands and on rocky slopes from N. 

 Eng., south to N. Car., and west to Neb., S. Dak., and 

 Mo. The name from the Greek, meaning twice-spurred.
