Listera convallarioides  (Broad-leaved Twayblade)
Orchidaceae  (Orchid Family)

Montane. Spruce, Fir, and Pine forests and openings.

Robert Brown named this genus for the British naturalist, Dr. Martin Lister (1638-1711), and the species was named by John Torrey in 1826. 

"Convallarioides", means “like convallaria”, referring to the supposed resemblance to the "Lilly of the Valley” plants.
