Habenaria hyperborea, E. Br. Twin Lakes. (965.) 

 H. DiLATATA, Gray. This and the preceding are .doubtless distinct 

 species, and I have endeavored to act upon this' belief. I confess, 

 however, to my inability to find a real constant difference that might 

 stand as a specific test. Even the careful figures of Mr. Watson do 

 not always decide. 1 place more dependence on the hooded posterior 

 sepal that Mr. Watson points out than on the measurements, though 

 even this seems a mere question of degree. The fact may be worth 

 noting that most of these specimens grew in the same place, and side 

 by side.
