A FEW NATIVE ORCHIDS I?5

 sumption with regard to a flower, which is un- 

 fortunate enough to show no sign of nerves or 

 gray matter in its composition. Who shall claim 

 to know his orchid who knows not its insect 

 sponsor ? 



To take one of our own wild species. Here is 

 the Arethusa bulbosa of Linnaeus, for instance. 

 Its pollen must reach its stigma so he supposed 

 in order for the flower to become fruitful. But 

 this is clearly impossible, as the pollen never 

 leaves its tightly closed box unless removed by 

 outside aid, which aid must also be required to 

 place it upon the stigma. This problem, which 

 confronted him in practically every orchid he met, 

 Linnaeus, nor none of his contemporaries, nor in-

Not until the time of Christian Conrad Spren- 

 gel (1735) did this and other similar riddles begin 

 to be cleared up, that distinguished observer hav-
