Hab. From Lake Winipeg to the RockyMountains, and as far north as Bear Lake, in Iat, 66°. Dr.
Richardson; Drummond.—“ The Créés and the Stone Indians gather its roots in the Spring as an article of
food.” Rich.—After the excellent description- above-quoted, made from the recent plant, I have little to
remark. The perfect fruit, which was unknown to Dr. Richardson, has now been seen in abundance and
proves the genus to be Phaca, rather than Astragalus.

10. P. glabriuscuta ; glabra vel pilis raris muiutis sparsa, caule erecto subsimplice

compressis membranaceis glabris.
Hab. Yallies of the Rocky Mountains. Drummond.—General aspect very similar to the preceding, of
which it may perhaps be a variety; but it is almost entirely, and especially in the leaflets, glabrous; smaller too
in all its parts, and the fruit is much narrower, more falcate, and, in the scarcely mature state, exceedingly
compressed. It seems to be rare, as very few specimens were gathered, but those are both in flower and fruit.
11. P.elegans; subglabra, caule subramoso erecto vel assurgente angulato, foliolis
S—*7-jugis oblongis obtusis basi cuneatis supra glabris subtus pilis minutis appressis,

velutinis apiculatis 3-5-spermis.—fi. minor; caule ascéndente minore, racemo breviore.
Hab. Prairies in the Rocky Mountains, and. A on the higher summits of the mountains. Drummond._
This grows in the plains to the height of a foot, or a foot and a half, erect, having leaflets nearly an inch
long, somewhat glaucous beneath, flowers bright and deep purplish-blue, in a compact raceme ; these racemes
elongate considerably as the fruit ripens, and bear ovate, very densely hairy, blackish legumes, about three-
fonrths of an inch long. Var. A is smaller in all its parts, has smaller and rounded racemes, with more
patent flowers, and approaches the P. astragalina; but its flowers are always considerably smaller, of a fhr
deeper colour, and the leaflets are much narrower.' It is a very elegant species.

Hab. From Newfoundland and Labrador (Mr. Morrison) on the east, to the Rocky Mountains

the north. Dr. Richardson ; Capt. Sir E. Parry, fyc.

Hab. Plains of the Saskatchewan. Drummond.—Stems 1 to 2 feet long, scarcely branched. Leaves
4 to 6 inches long. Leaflets an inch long. Racemes, including the peduncle, 6 to 8 or 10 inches in length,
with numerous closely-placed, drooping, rich purpleyfowers, nearly an inch long; carina and alee pale at their
base, i Legumes pendent, an inch long, between membranaceous and cartilaginous, narrow, cylindrical, acute
at the point, with the style often deciduous, at the base attenuated into a stipes as long as the calyx, one-celled
but having two furrows on the upper side, one on each side of the suture, which form two prominent ridges
within the cell. Seeds 5-6, reniform, each upon a slender stalk of about its own length.

Hab. Kotzebue’s Sound. Lay and Collie.—The specimens from Capt. Beechey’s Collection precisely
accord with those .sent me from the opposite side of Behring’s Straits, by Dr. Fischer. One of the individuals
has some, apparently monstrous, bracteee, which are foliaceous, and longer than the flowers.
