Hab. Alpine rivulets in the Rocky Mountains. Drvmmond, Labrador. Rev. Mr. Kohlmeistcr, Dr. 

 Morrison. «. and /3. Observatory Inlet^ Nortli-West America, lat, 56°. — Like WaUenberg and Homemann, 

 I am unable to separate the /3. (JE. Ilomemanni of Reichenbacb) from E. aipinum, as a distinct species; 

 especially as I possess, amongst several northern specimens, the most evident transitions. A very good figure 

 of a. is given in English Botany, and the North American plant corresponds no less T\'ith that figure than 

 with specimens from the Scottish Alps, which I owe to the kindness of Professor Hooker.

Hab. Alpine ^oods, sides of rivulets, and shady elevated spots on the Rocky Mountains, from lat. 52° to 

 36°. Drummond. Unalaschka. Chamisso. — In habit, especially the small specimens, more nearly allied to E. 

 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.

Hab. Ciunberlaud-IIouse Fort, on the Saskatchawan. Drummond. — This plant, as to specific character, 

 is almost intermediate bet^veen E. origanifolium and E. tetragonumy 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. glanduhsum. H.]

Hab. Canada, throughout the plains to lat. G4°, and to the valleys of the Rocky Moimtains, frequent 

 North-West coast, near the sea. Douglas, Dr. Scauler.—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 some- 

 tunes only the two pair beneath are opposite, and again, sometimes all the leaves upwards to the head of 

 the stem, are so.
