124 OUR NATIVE ORCHIDS 



This species has a very wide range, extending from New- 

 foundland to Ontario and Minnesota, south to Florida, 

 Alabama and Missouri. It is found at an altitude of 4,000 

 feet in the mountains of North Carolina. It blooms through 



July. 



A curious little note by Baldwin in his "Orchids of New 

 England" offers a suggestion for observation. He says that 

 it was observed by a naturalist of Ottawa, Canada, that in 

 1882 the Green Adder's-mouth was very common in that 

 region, while few specimens of the White Adder's-mouth 

 could be found. In 1883 the reverse was the case. The 

 White was abundant, and only one or two plants of the other 

 species noted. He adds that "This habit of appearing and 

 disappearing without apparent reason is another charm of 

 the Orchis family."
