Hab. Frequent on all the coasts of America, bordering on Behring’s Straits. Chamisso.—This plant
Chamisso and Schlechtendal observe to be nearly allied to C. viscosum, and still more to C. alpinum; and
they even think that the C. alpinum of Melville Island, and other arctic regions explored by our navigators,
is identical with it. The Cerastium brought by Capt. Beechey from Kotzebue’s Sound, I unite,
without any hesitation, to a very common state of C. alpinum.

observes, in the Appendix to Capt. Sir John Franklin’s 1st Voyage, that a similar plant to this, but with
more rigid pubescence, and gathered on the shores of the Arctic Sea, existed in the collection that was lost.
It was probably the C. Fischerianum, if that he really a distinct species, which Chamisso says is distinguished
from C. alpinum, among other marks, by its more rigid pubescence.

which with Mr. Goldie, I was formerly disposed to keep distinct from C. arvense, I now think scarcely
deserving to rank as a species. It is indeed larger and stronger in all its parts, and the petals are much more
conspicuous. But there are intermediate states which diminish the value of those characters.

Dr. Richardson; Drummond; Douglas. Common in North-West America, where, the timber has
been destroyed by fire. Douglas. /?_. About Lake Winipeg. Drummond.—Annual. This is amongst the
tallest of the genus, a foot high, very erect; in young plants the flowers are few and somewhat umbelled; the
old plants bear large and many-flowered panicles. The leaves are often two inches and more long. Var. /3. is
very remarkable for the loose cobwebby down which covers the whole plant; but as the specimens thus
clothed are, though in flower, evidently young, it is probable that this additional covering disappears in age.
All our specimens are, indeed, more or less densely clothed with down.

is erect, rigid, everywhere clothed with patent rigid hairs, and inhabits Siberia. Chamisso says that his
Unalaschka specimens are similar, but smaller.

Hab. Abundant in the plains of the interior, especially about the Saskatchawan. Dr. Richardson;
Drummond; Douglas.—This is amongst the most distinct of all the species of Linum, yet scarcely known to
any author, except Pursh and Torrey, and by them only as a native of the Missouri. I possess beautiful
specimens from Dr. Boott, gathered near Boston; and I have it from Mr. Nuttall as “ L. stria tum gathered
at New Hasler; but this latter species should have ovate or oblong leaves and blue flowers.—The beautifully
spinuloso-serrate and glandular calyces at once characterise the present species.
