foundland has almost setaceous leaves, and seems only to differ from Reichenbach’s representation of the
following species by its stouter stem. Dr. Richardson’s specimens accord in every particular with those of
Europe.

stem so slender, that the plant has almost the habit of Galium.

and Bay of Eschscholtz. Chamisso. Kotzebue’s Sound. Lay and Collie.—Not only are the leaves of this
species much broader than in H. vulgaris; but, as Mr. Brown observes (in-Richardson, App. 1. c.), their extremities
are not sphacelated, or they are so only in a very slight degree. The specimens from Hudson’s
Bay are a foot and a half tall, bearing leaves more than an inch long; while that from Labrador does not
exceed a span in height, with leaves one-third of an inch long.
