the Mackenzie River. Dr. Richardson.—This, and the following, with O. Americana, L. (which I possess
from various parts of the United States, and from Mexico,) doubtless constitute a good genus, Boschnajakia
of Bunge: but I regret I do not know where that author has described it. His specimens from Eastern
Siberia are precisely the same as those gathered by Mr. Menzies and Dr. Richardson, and are remarkable
for the very imperfect lower lip of the corolla, by which the species is at once distinguished from O. Americana,
as well as.from the following.

H ab. N.W. Coast of America. A . Menzies, Esq.—This is remarkable for its decidedly tuberous roots,
and by that character, as well by the very dark brown opaque (not pale brown and shining) scales of the
stem, it may readily be known from ihe O. Americana, L., which has not, I believe, yet been detected
in British North America.

met with the same plant-in Teams, (1st Coll. n. 69). Mr. Douglas’ specimens are. taller,.more generally
branched, and more hoary with down: the calyx is often 6-cleft, the upper lip of the corolla sometimes
nearly entire; but 1 do not see that they are otherwise different from those of the eastern side of the
Rocky Mountains.

Probably introduced; yet both Pursh and Torrey observe that it springs up in great abundance in
• A desire not to extend the present work beyond the two volumes announced in the prospectus, has induced me
to omit the generic and specific characters, and particular references of well-known plants. Without such an arrangement,
it would be impossible to include all the speci'es, even of pheenogamous plants, within the prescribed limits; the
number having considerably accumulated since the commencement of the work.
