ORCHIDACE^ 



This plant when well developed can be distinguished readily H. hyper 

 by its very saccate spur, but it passes so gradually into the typical 

 form of H. hyperborea that it is not worthy of more than varie- 

 tal rank. Dr. Rydberg describes the flowers as purplish. It is to 

 be regretted that this indefinite term has been used to charac- 

 terize the flowers of a species of the H. hyperborea group.
