A Humming Bird Flower 



The common nasturtium may be taken as a type of 

 flower which advertises to the birds rather than to the bees. 

 The honey is stored at the bottom of a long tube down which a 

 bee could hardly stretch its proboscis. In many other ways, 

 including the arrangement of the stamens and pistils, 

 bird flowers show their adaptation to the partner- 

 ship which their ancestors have built up.
