Hab. From Canada, (Mrs. Percival,) throughout North America, among the Rocky Mountains, (Drummond,
Douglas,) to the shores of the Pacific, (.Douglas,) and as far north as the shores of the Arctic Sea,
Dr. Richardson.—Chamisso and Schlechtendal unite with this, and, I think, justly, L. austriacum, Jacq., L.
Iceve, Scop, and L. alpinum, Jacq.; for the differences are indeed very trifling and very inconstant. At the same
time, those authors distinguish the L. perenne from our British L. perenne, (L. anglicum, Mill, and De Cand.)
by its “ drooping capsule, whereas inX. anglicum it is constantly erect:” a character, perhaps, on which
too much stress is laid, even were it constant; but in my American specimens, often on the same plant, the
capsules are sometimes erect and sometimes drooping. Although this species of Flax is of such general
occurrence in North America, Pursh and Douglas both observe that it is never employed by the natives for
economical purposes.
