Uralensis, 0. microphylla, exactly correspond with the more usual state of our plant. Mr. Drummond’s var.
from the most elevated ridges of the Rocky Mountains has the leaves, especially the old ones, nearly
glabrous, the leaflets narrow; the legume greatly swollen, or inflated, thin and membranaceous, scarcely
at all hairy.
4. O. foliolosd ; acaulis, incano-villosa, foliis numerosis, foliolis approximates ovatis

Hab. From Carlton-House to the Rocky Mountains, in lat. 54°.—This very elegant species Of Oxytropis
has an affinity on the one hand with O. montana, and on the other with O. ccerulea; agreeing with both in
the general shape of the leaflets, and their regular and close insertion upon the rachis, and in the deep-blue
colour of the flowers, pale at the base of the petals. From the former it differs in its more compact and tufted
growth, smaller heads, and smaller and more patent flowers, and in the drooping, cylindrical, very black, and
hairy legumes ; from the latter, in its less silvery foliage, more obtuse leaflets, and far shorter and more
compact heads of flowers.

Canadian specimens from Lady Dalhousie and Mrs. Percival much more resemble the figures in the
Botanical Magazine and Register, than those from the more western parts of North America: and certainly,
as Mr. Lindley observes, approach the O. grandiflora, as they do also the O. ambigua; both natives of
Siberia. Nor is this species far removed, or readily distinguished by words, from some states of O. Uralensis.
7. O. nigrescens; subacaulis, multiceps, procumbens, foliolis 7-11 ellipticis acutiusculis

Capt. Sir J. Franklin and Capt. Back; Capt. Sir R. Parry, $-c._In the degree of pubescence, in the form
of the leaflets, in .the colour of the hairs of the calyx, and size of the flowers, this plant is very variable.
The var. y. sulphurea, corresponding almost exactly with the O. sulphurea of Dr. Fischer, (the O. campestris
>. of De Candolle,) is exceedingly beautiful, not only in the silkiness of its foliage, but in the size and bright
ness of the corollas.
