H ab. Arctic Sea-Coast. Dr. Richardson. f3. Rocky Mountains. Mr. Drummond._This affords another
instance of the occurrence of the, same species at the level of the sea in the north, as well as at a
certain height in lower latitudes. It approaches nearly to G. propinqua, Rich., but it seems to differ
constantly, since its exterior habit, and the manner of its ramification, is indeed anything but analogous.
In Chamisso’s specimens of the latter species, the lobes of the corolla are lanceolate, and not superincumbent,
at their basej_ but, among that great serigsof specimens which have been collected on Capt.
Franklin’s expedition, are to be found flowers wholly similar to those of G. arctopJiila, differing, indeed,
only in having their corolla always much slenderer and narrower at the base of its tube, as well as somewhat
serrated at its lobes.

Hab. Alpine swamps in the Rocky Mountains (ilfr. Drummond), together with the variety. Cumberland
House to Bear Lake, and Bear Lake River. Dr. Richardson. Escholtz’s Bay, Chamisso.—'This
species is chiefly characterised by a great many small branches or flagella, which rise from the axillee
of the radical leaves, and from the inferior ones of the stem. They are very slender, one or two inches
long, commonly with one pair of leaves and one terminal flower, which is considerably smaller than the
flowers of the stem. There are specimens with twenty such branchlets. This species grows along with
G. acuta, Mich., some forms of which are so strikingly like this plant, that one would easily think them
not specifically different, the more so as the beard of G. acuta sometimes almost totally disappears, and
the existence Of glands between the filaments in the section Arciophila is also variable. The cuspidate
lobes of the corolla, however, afford a character which never fails.—The original specimens did not present
a 5-cleft corolla; but this is a point of no value at all in this group of Gentiance, and Chamisso’s and
Richardson’s plants are quite the same. In the drawing of Mr. Bunge, the shape of the leaves, and of the
lobes of the corolla, is not well given.—The variety f3. is in fact so similar to G. aleutica, Cham., that it is
impossible to distinguish them in any other way than by the calyx, the lobes of which are regular in the
latter, and united in a tube half as long as themselves. Also, the leaves of thè stem are still larger and
more stem-clasping. It seems that the constancy of these characters is still to be proved by investigations
on the spot. Transition forms between that variety and the common appearance of G. propinqua, Rich.,
are frequent.

H ab. At the Mackenzie River. Cumberland House to Bear Lake. Dr. Richardson.—There is no
species of the least analogy with this in the group of Arctophilce, the appearance being exactly that of G.
Amarella, or G. acuta; but as glands occur between the filaments, which have not been observed in the
group of Endotrichas, and on the other hand, as there is seldom a trace of a beard in the corolla, it will
be more convenient to bring this species into this group, although it must be observed that it unites most
naturally with that of G. Amarella. Besides, it differs from the latter by the peculiar form of the leaves,
and of the lobes of the corolla.
