are more stout and succulent, while the greater number of 

 species common to the American coast than appear in St. Law- 

 rence's Cove, indicate a more temperate climate. On the 

 island of that name, we gathered Alnus incana, as a very dimi- 

 nutive shrub, and Spircea cJiamcBdrifoUa, both of which we had 

 remarked at Kamtschatka, and not on the American Island 

 Unalaschka ; and which a sterner atmosphere seems to have 

 driven from St. Lawrence's Cove. An Orobanche and a 

 Pinguicula are among the plants of this island. The Ciner- 

 ana palustris grows with remarkable luxuriance in the well 

 watered slopes formed at the base of the mounds of ice; while 

 i>etula nana is seen even on the very shores. The plain 

 country of this island is free from snow throughout the 



summer.

The species of this genus, found by Dr. Gillies in South 

 America, and chiefly in the Cordilleras, both on their eastern 

 and western sides, are not numerous, and their illustration

°ian, Sprengel, and more especially of Koch and De Can- 

 aoUe. The country in question seems to be, more par- 

 ticularly, the district of the Mulinea, a subtribe of De Can- 

 «oHe, of which the genera are less satisfactorily determined 

 *an those of the other groupes of the order; and to me it 

 JPPears tliat Fragosa, Ruiz et Pa v. and Pedophytum of 

 plinth, should be removed from the Hydrocotylea, where 

 ^e Candolle has nlicfid them, and arranged with the Mu- 



^inece.
