Throughout the Northern states, in similar situations with 
the preceding : not uncommon. Flowers in July. 
Obs. This species differs from the preceding principally in 
having greenish-yellow flowers, with a lanceolate lip which is 
not dilated at the base. The spur is about one half the length 
of the ovarium, obtuse or somewhat acute and incurved. The 
size of the plant is quite variable. It often occurs 6 — 12 inches 
in height, with a somewhat ovate or oblong spike of flowers. 
In this state it agrees entirely with specimens of H. hyperborea 
collected in the arctic regions of America by Dr. Richardson. 
In favourable situations it not unfrequently attains the height of 
2 or 3 feet, with a virgate spike 6 — 8 inches in length, and in 
this state is the H. dilatata of most American botanists.
