THE FLOWER AND THE BEE 



Fig. 95. Red Poppy. Papaver Rhoeas 

 A pollen-flower 



nisms, previously acquired, very useful. In the flowers of the 

 tick-trefoil {Desmodiiim), which are pollinated by bumblebees, 

 the stamens are held under tension and shed their pollen while 

 enclosed in the keel. When a bumblebee alights on the wings, 

 the anthers are released and the elastic filaments project the 

 pollen up in the air, as though there had been a shght explosion.
