the shade of pines on the dry sandy plains of the Columbia.—This seems to be a rare species, only
hitherto known from specimens gathered by Mr. Nuttall on the sandy deserts of the Missouri. It differs
from all the other described species remarkably, with the exception of the following, and, perhaps, V.
hastata of Michaux, with which l am unacquainted.

The North-West American specimens havé been called V. Scculerii in Mr. Douglas’s MSS., but I do not see
how they differ from the common state of the plant. They are indeed smaller and quite glabrous.

Hab. Hilly wooded places near Fort Vancouver, and in the high grounds of Lewis and Clark’s River,
North-West America. Douglas.—My specimens of this are imperfect; and I am not sure that there are not
two species among them: the one, probably from which the above character was mainly taken, throwing
out wiry stems, like the runners of a strawberry, and bearing leaves, (as does the root,) which are more
inclining to oval than reniform, of a coriaceous texture and brownish hue from the numerous small dots
which cover both their surfaces, and having a few thick white hairs on the upper side. This is in fruit and
has a ripe and burst capsule upon one of the runners, whose footstalk is equal in length with the leaf. The
other plant has no stolones: the pate green, almost reniform, leaves are quite destitute of dots, and have an
injured flower arising from the root. Mr. Douglas describes the species as a handsome one with bright
yellow blossoms, marked with brown or red veins.
