(Fig. 4.) This species is closely related to the true L. Jiypci'lwrca, and is its representative in the west. It differs only in the lighter green flower and the^thicker and shorter spur. It is also related to L. horcalis on the other hand, and it is no wonder that Chamisso made it a variety^of that species, as it differs only in the green flowers and more saccate spur. Intermediate forms are met with ; these [are 'perhaps of hybrid origin. L. viridiflora is common in the Rocky Mountain regions and the Cascades. Its range ex- tends from southern Alaska to North Dakota, central Nebraska and Colorado, and is the common plant of the West, known as Habenaria Jiypcrborea. Numerous specimens have been examined.
