(which is also founds though dwarfish, on the hills,) Epilobhmi 

 luteum, and Mimulus guttatus (Willd.*), Claytonia unalascJi- 

 kensis (Fisch.), and sihirica {alsinoides ? Pursh), may be also 

 reckoned here. Sanguisorha canadensis^ Lithospennum an- 

 gustifolium^ &c. belong to the common Flora of America. 



Many species of Grasses thrive in the low lands, w^ith some 

 UmbeHaicBy such as Angelica^ Heracleiim^ &c. A dozen Caricesj 

 scarcely forming a larger proportion of the vegetation tlian 

 in the north of Germany ; some Scirpi and Eriophora accom- 

 pany them, with a few Junci^ in the proportion of about one to 

 two. The OrcMdem constitute a groupe of some importance, 

 both because of the number of species and the beauty of the 

 individuals; they prevail both in the vallies and on the hills ; 

 and we counted eleven kinds : among them a beautiful Cypri- 

 pedium. Higher north, we did not observe a single plant of this 

 family. Of the Ferns we found about eight species; nearer to 

 the Pole there is but one Filix^ and even of this we only saw 

 a solitary specimen. At Unalaschka there are some Lycopo- 

 dia; in the more arctic regions but one. We found in the 

 lakes many water-plants ; Potamogeton, Sparganium^ Ramm- 

 cuius aqnatilis^ &c. ; in the higher latitudes we observed only 

 the two species of Hippuris^ and the common CaJlitriche. 



Tw^o other Ranuncula^ the Prunella vulgaris^ a species of 

 Minanthus, of Cinerariay AchillcEa, Plantago, and Geim, some 

 HubiacecB, a Clayto7iia, the MemjantJies trifoliata, a Triglochin, 

 &c. belong, with the other above-mentioned plants, to the 

 Flora of the vallies of Unalaschka. We saw also a Bartsia, 

 apparently different from the Bartsia pallida of more nor- 

 therly situations. To a beautiful plant, which constitutes a new 

 and distinct genus, w^e gave the appellation of Romanzoffia 

 ^mlaschkensis, in commemoration of the noble promoter of all 

 science in Russia. The genera Eumejc, Polygonum^ Aconi- 

 f^% Thalictrum, some Alsimce, the Iris sibirica, Geranium 

 pratense, Comarum pratense, and Montia fontana are distri- 

 t>uted all over these arctic re^rions.
