Hab. Frequent in the arid Prairies near the Blue Mountains of Lewis River, North-West America.
Douglas.—This is perhaps the most beautiful species of the genus, and well deserving of the name
which Mr. Douglas has given to it. The spikes are large, densely clothed with spreading silky hairs, among
which the rose-coloured petals appear. The leaves are perhaps more remarkable in their dry than in their
fresh state; for in the Herbarium, the upper-side becomes of a rich verdigris-green. The same change of
colour takes place, though in a very inferior degree, in some of the specimens of P. candidum in my collection.

Hab. Banks of the Saskatchewan. Drummond.—“ This,” Mr. Douglas observes, “ has perhaps a greater
range than almost any other plant in North America. It is common in the western territories of the United
States, (where, on the banks of the Missouri, at St. Louis, it was first discovered by Bradbury,) throughout
the temperate parts of the British Possessions, (as about Hudson’s Bay, the Red, Saskatchawan, Assinaboin,
and Athabasca Rivers,) and upon all the intervening plains; and is equally abundant on the west side
of the Rocky Mountains, from the source of the Columbia to its confluence with the sea, and from
Cape Mendocina, in lat. 47®, to Puget Sound on the shores of the Pacific.” It is, therefore, not without
reason that Mr. Nuttall suspected this was the Liquorice, mentioned by Sir A. Mackenzie as indigenous to
the coasts of the Pacific Ocean, which Dr. Richardson determined to be the Hedysarum Mackenzii. It
will be remarkable if this species should prove the same as a North African one. Mr. Nuttall, indeed,
alludes to its similarity -with the G. fcetida of Desfontaines; observing, that, like that, it emits a somewhat
disagreeable resinous odour: but he does not say how they differ. I have compared our American species
both with Desfontaines’ description and figure, and with specimens gathered by Saltzman at Tangiers; and
I confess, as far as can be judged from these authorities, I can find no distinguishing character whatever.
The number of seeds is variable in both. The little scales on the underside of the leaves are the same in
both and they are formed by a resinous exudation from the glands, which abound, as in Psoralea and
Petalostemon, and which are scarcely different in colour from the leaf itself.

Dr. Sims in the Bot. Mag. t. 2112, is the representation of a specimen which flowered in Mr. Lambert’s
garden; from which place also I possess an individual under the same name, and probably taken from the
same plant. But this I would unquestionably refer to the A. fruticosa. Mr. Douglas’ plant is truly distinct
from this, having all the teeth narrow-subulate, as described by Mr. Nuttall. The leaves, too, are dotted with
large pellucid glands, there are resinous brown glands on the calyx, and it forms an exceedingly compact
shrub, with copious foliage, and very small rigid leaflets.
