All the Coralroots are mycotrophic, that is they tap into a fungus on the roots of other plants and use it to obtain their nutrients. They have no need for chlorophyll, therefore, and these are completely without chlorophyll or leaves.
The Striped Coralroot, Corallorhiza striata var. striata, has the largest and showiest of the five Coralroots here in the northwest. These were photographed on Padden Ridge in the Bellingham area and are paler in color than many I have seen.
