PRIMULACEiE. iSamolus. 



dorffi Chamisso fin Herb, nosir.) The same plant is found at Karatschatka by Pallas, Langsdorff, and 



Beechey. The* long leafy stem, and obovate very obtuse foliage, give a remarkable appearance to the 



plant ; and I cannot but think that this very northern Trientalis is, like the preceding, a really distinct 

 species. It has quite the habit of a Samolus. In all, the number of the parts of the flower varies from 6, 

 which is most usual, to 7. In this and the preceding, the margins of the leaves are quite entire, in the 

 T, Americana and Europcea slightly (but when seen under a microscope distinctly) serrulated.

 received the same plant from Dr Schweinitz from Pennsylvania, and from English gardens, as the Z. anguS' 

 tifolia, Mich., but whether it be so or not I have no means of determining. The L, quadri/olia, Bot. Mag. 

 t. 660 (i. longifoUa, Ph.) much resembles it also. It is of a very dry and harsh character, and Dr Torrey 

 not unaptly compares its aspect with, that of Hypericum galioides : but the foliage is larger and coarser. 

 Young leaves frequently arising from the axils of the older ones, give them an appearance of being verticillate.
