Hab. Canada; from Quebec to the St. Lawrence. Michaux. Plains of the Saskatchawan. Dr. Richardson,
Drummond.—Of this plant I find only two or three specimens in the Collection, and these, on a hasty
glance, I confess I had been disposed to mingle with those of P . Norvegica. But I am now inclined to concur
with Dr. Richardson in keeping them distinct. H e figure of Nestler, above quoted, is very faithful, and
the upright .unbranched stems, with a few-flowered terminal panicle, are characteristic, [IT.]

* K ohlmeister is the'correct spelling of this name, as I have lately ascertained; though it has been written Kol-
master before in this work, and Colmaster in Pursh’s Flora. This gentleman, the Rev. B enjamin Gotleib
K ohlmeister, resided many years as a Moravian Missionary in Labrador, and made a beautiful collection of the plants,
with the use of which I have been obligingly favoured by the Rev. P. Latrobe.

Hab. Dry and elevated ridges of the Rocky Mountains, between lat 52° and 56®. Drummond. Shores

Parry, Capt. Sabine.—This is a very beautiful species, with the flowers large in proportion to the size of
the plant, and the petals very broad; but I possess many specimens of a Potentilla from the higher summits
of the Rocky Mountains and from the Arctic regions, which appear to be quite intermediate between P.
Vahliana and P . nivea. The latter has in general much smaller flowers, but which are larger frequently
as the plant becomes smaller, in very arctic or very alpine situations. [H.]

Hab. Labrador. Rev. B. Kohlmeister (in Herb, nostr.) Mountains and alpine Prairies, from Carlton-
House, to the Rocky Mountains, Drummond; and to the shores of the Arctic Sea (Dr. Richardson), and
islands of the Arctic Ocean, ( Capt. Ross, Capt. Sir E. Parry, Capt. Sabine,) where also var. /3. is found,
as well as at Labrador. Dr. Morrison.—This species also, in North America, appears, in regard to the pubescence
of the whole plant, size, and number of the flowers, a very variable one. Though the size of the petals
is subject to many changes, it depends however on that of the calyx, in as much as a larger calyx has
always in proportion larger petals.* Another deviation from the usual state of the plant I find in the North
American plants of this species, namely, that sometimes (as in P. subacaulis) there are found some leaves
quinate: these are apparent on vigorous specimens, the flowers of which are numerous and small. In other
respects there is no difference. Lehm.
