Gymnadenia.} ORCHIDEiE. 



195 



\ 



Hab, Between Norway House and Cumberland House Fort, on the Saskatchawan, Drummond ; rzxe, 

 and with fruit and good foliage ; but no flower.— Flowers similar to those of Corallorhiza^ Root tuberous, 

 with a single elliptical leaf from the summit of the tuber, the scape springing from beneath. This is doubt- 

 less the northern limit of this fine Orchideous plant ; but it does not appear to have been found in Canada.
