Morrison, a. and /3. Observatory Inlet, North-West America, lat. 56°.—Like Walilenberg and Hornemann,
I am unable to separate the /3. (E. Hornemanni of Reichenbach) from E. alpinum, as a distinct species;
especially as I possess, amongst several northern specimens, the most evident transitions. A very good figure
of as. is given in English Botany, and the North American plant corresponds no less with that figure than
with specimens from the Scottish Alps, which I owe to the kindness of Professor Hooker.

alpinum than to E. montanum. This is, in North America as well as in Europe, a very variable plant; it is
found in the former country from about five inches to upwards of a foot and more in height, with red and
with white flowers, the last often half as large again as in the common form.
6. E. glandulosum, (Lekm.); caule simplici basi repente angulato glabro, foliis sessilibus
ovato-lanceolatis subdecurrentibus acutis glanduloso-denticulatis, floribus erectis, stigmate
clavato, capsulis sessilibus angulis tenuissime pubescentibus.

subpilosa, colorata. Petala obcordata, nervosa, alba, calycibus longiora. Stamina brevia, erecta. Stigma
clavatum. Capsula (junior) sessilis, angulis tenuissime pilosis, pilis glanduliferis.
Hab. Cumberland-House Fort, on the Saskatchewan. Drummond.—This plant, as to specific character,
is almost intermediate between E. origanifolium and E. tetragonum, approaching the first more in habit,
but distinct by its sessile decurrent leaves and sessile capsules. This sessile capsule, which appears,
moreover, only somewhat hairy at the angles, the leaves more toothed than serrated, and the simple stem,
readily distinguish it from E. tetragonum.—[I possess, from the North-West coast of America, gathered by
Mr. Douglas and Dr. Scouler, what I consider to be an unbranched variety of E. tetragonum; but which
yet I am unable to distinguish from E. glandulosum. 221]

Hab. Canada, throughout the plains to lat. 64°, and to the valleys of the Rocky Mountains, frequent.
North-West coast, near the sea. Douglas, Dr. Scouler.—A very [variable plant, with almost simple, or
with much branched, totally glabrous or pubescent stems, of which the angular sides appear often more and
often less rounded, and even entirely disappearing, on very vigorous specimens, at the base. Of the leaves sometimes
only the two pair beneath are opposite, and again, sometimes all the leaves upwards to the head of
the stem, are so.

Hab. «. Labrador. Dr. Morrison, ß. Throughout Canada, and as far north as lat. 64°, and among the
Prairies of the Rocky Mountains. Dr. Richardson, Drummond.—Amongst several plants sent by Mr. Drummond,
only the var. ß. was found, distinguished from the primary form by its much smaller, almost
white flowers and simple stem, but which is also seen in Northern Germany, in turfy soil, with all the
intermediate transitions. E. davuricum, Fisch. (De Cand. Prodr. v. 3. p. 42,) appertains to this variety.
—The var. ß. corresponds with the E. palustre of Dr. Richardson, and is sometimes branched, when it is
identical with the E. lineare of Muhl. Cat. and of Bigelow, which De Candolle refers to E. squamatum,
