This is near L. plicata and L. Uchiyame, but distinguishable 
from them by the longer and more slender column of the flowers. 
The columns of the other species are very much shorter; also 
very near Liparis viridifiora L., but differs from it in having 
larger flowers and in the lips with obscure lobes.
