These tiny orchids are extremely common in moist forests throughout the PNW, but their minute flowers (only 6mm across!) and uniform green coloration make them easy to miss. Recent genetic research has placed all members of the genus Listera into the old world genus Neottia which used to contain a single, achlorophyllous species, but I’m really more of a lumper than a splitter, so I won’t be changing my taxonomy for a while!
