CORALLORHIZA 



C. innata, R. Br. Two specimens of C. innata, found June 4, 1901, in dense 

 shade in swampy woods, show the condition known as irregular peloria. 

 In this case a conversion of the petals into normal or nearly normal lips 

 gives a remarkable appearance to the flowering spike. This is more 

 common in cultivated orchids than in wild plants and I have to thank 

 Mr. Oakes Ames for explaining to me the singular anomaly in these 

 specimens.
