differs in no respect from our European L. Loeselii. The American plant is indeed often much
larger, (I have specimens more than a span high,) but Dr Richardson’s specimens do not exceed ours.

H a b . Between Norway House and Cumberland House Fort, on the Saskatchawan, Drummonds rare,
and with fruit and good foliage j 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 doubtless
the northern limit of this fine Orchideous plant j but it does not appear to have been found in Canada.
