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 Alniis incana, as a very dimi- 

 nutive shrub, and Spircea chamcedinfoUai 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 Orohanche and a 

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

 aria palustris grows with remarkable luxuriance in the well 

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

 Betula nana is seen even on the very shores. The plain 

 country of this island is free from snow throughout the 

 summer.

ON THE PLANTS OF THE NATURAL ORDER 



UMBELLIFERiE, 



Detected by Dr. Gillies in the extra tropical parts of 



South America. 



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 

 has been greatly facilitated by the recent labours of Hoff- 

 man, Sprengel, and more especially of Koch and De Can- 

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

 ticularly, the district of the MulinecB^ a subtribe of De Can- 

 dolle, of which the genera are less satisfactorily determined 

 than those of the other groupes of the order ; and to me it 

 appears that Fragosa, Ruiz et Pav. and Pectophytum of 

 Kunth, should be removed from the HydrocotylecB, where 

 De Candolle has placed them, and arranged with the Mu- 

 linece.
