Hab. Lake Huron. Dr. Todd.—Mr. Borrer observes that this species is probably the same as Pursh’s
R. laevigata, since it agrees very well with his character ; but the leaves are pubescent, and the leaf-stalks
have no prickles.
I am indebted to my kind and valued friend Mr. Borrer for the determination of the above species of thi«
most difficult genus. There are still some dubious ones in the Collection, and two or three that are probably
new from the Pacific side of the Continent j but till we are supplied with more copious and better specimens,
we shall not attempt to define them.

however, not unfrequent in the southern States. In the northern, I am disposed to think that C. glandulosa
has been mistaken for it. I possess beautiful specimens from Dr. Schweinitz, gathered in Pennsylvania.

Hab. /3. Common on the banks of streams on the North-West Coast of America. Douglas, Dr. Scouler.
—Of the wood of this, and of Pyrus rimlaris, the Indian tribes on the Pacific make their wedges for splitting
trees. Mr. Douglas’s plant, thus named, seems to come too near C. glandulosa, and its leaves are certainly
not unfrequently lobed or angled. Two varieties are in Mr. Douglas’s collection from the North-West
coast ; both, indeed, with short thorns ; one is glabrous in every part, the other has the peduncles, calyces,
and under-side of the leaves downy.
