Hab. «. On limestone rocks of the Red River, and south towards Pembina. Douglas. /3. From
Cumberland-House on the Saskatchawan, north to Fort-Franklin and the Bear Lake, and west to the dry
Prairies of the Rocky Mountains. Dr. Richardson; Drummond.—This belongs to the same groupe of
Verticillares ” "with the true O. oxyphylla of Pallas, which I possess from Pallas’ Herbarium, through the
kindness of Mr. Lambert; and which is at once distinguished from this by its short, broad, and compact head
of flowers. It well deserves the name which Mr. Douglas has given it. Its blossoms are bright-blue, in
long spikes. In Dr. Richardson’s specimens, the fruit greatly exceeds the calyx in length; in Mr. Douglas’,
it is shorter; but as many of the flowers among the latter are abortive, I suspect that the fruit is imperfect too.

a. is the more frequent American form of this, plant. .The var. fi. differs in its more luxuriant growth, and
almost exactly resembles a plant which I possess from the Altai, sent to me by Mr. Prescott, and marked
“ Astragalus hypoglottidi affinis, sed legumina polysperma, sem. 4-8.” It approaches the A. onobrychioides.

Hab. Among rocks in the more elevated regions of the Rocky Mountains. Drummond.—This species,
so very different from any with which I am acquainted, belongs to the same division of the genus with
A. hypoglottis, and should perhaps be placed near to it. It is distinguished by its hoary stems and leaves,
by the small number of leaflets, by its few-flowered racemes, and small patent flowers on pedicels, which are
about as long as the bractea.

to which Dr. Richardson has ranged it,) that were the fruit discovered, it would probably prove to be a
Phaca also. The only specimen I have seen, has the flowers larger than in P. Aboriginorum.
