Lady Daffiousie; to the Saskatchawan, Dr. Richardson. Drummond. Shady woods, North-West America
in the lat. of the Columbia. Douglas.—Much confusion has existed, and I fear still exists, respecting the two
North American species of OsmorJiiza, both of which, by the less recent authors, have been considered as
one, under the name of Myrrhis Claytoni. They were separated by Dr. Torrey, and Dr. Bigelow, in their
respective publications which appeared in the same year, 1824: so that it is hard to say which has the
priority in regard to date. I have preferred the names given by De Candolle, as the most expressive of the
essentially distinguishing characters.
