Z'/ic Orchid Awaiting an Insect 



Flowers nre usually not only designed by their general 

 shape to attract insects, but their nectar store is often sur- 

 rounded by a tai-get of some kind — sometimes of color only, and 

 sometimes as in the case of the orchid, a folded leaf which guides the 

 insect in. Almost all flowers, in this way, have centers which 

 are white, or more brilliant than, or different from the 

 rest of their color, as if to lead the in.-<ect to its 

 work with the least possible delay. The 

 orchid's pollen may be seen in this 

 photograph print directly in the 

 center of the flower.
