DR. HOOKER ON THE DISTRIBUTION OF ARCTIC PLANTS. 
Kotzebuei* a 
found only on the White Mountains of New Hampshire, and Farnassia 
species which is scarcely different from palmtris. 
The only plants which are not members of the arctic flora elsewhere, and which are 
confined in Greenland to the temperate zone, besides the above American plants, are JBlitvm 
glaucum, Potamogeton marinus, Sparganium minimum, and Streptopus amplexifolius : the 
rest will all be found in the column of the arctic plant catalogue devoted to Greenland, 
where S. signifies that the species is found south only of the arctic circle in that country. 
On the other hand Temperate Greenland adds very materially to the number of Euro- 
pean Arct 
species that do not enter Eastern America (Arctic or Temperate) 
which the most remarkable

Gentiana aurea. 
Betula alpestris. 
Juncus trifidus. 
— squarrosus. 
Anthoxanthum odoratum 
Nardus stricta. 
Galium uliginosum. 
Another anomalous feature in the Greenland flora is the presence, on the East Arctic 
coast, of some species not found on the west, nor in the temperate southern end of the 
peninsula. These are : 
Lychnis dioica (Arctic Europe) . 
West 
West 
Deschampsia caespitosa (all arctic longitudes, but also absent in Spitzbergen). 
For data connected with the Greenland flora, I am mainly indebted to the collections 
of the various polar voyagers in search of a north-west passage, especially to Drs. Lyall's 
and Sutherland's ; to Lange's catalogue in Kincke's < Greenland '; and to the notices of 
Vahl, Greville, Sir William Hooker, &c, on the plants collected by Sabine, Scoresby, 
Koss, Jameson, Graah, and Vahl, &c. ; to Sutherland's appendix to Penny's voyage and 
Durand's to Kane's voyage. 
There is a curious affinity between Greenland and certain localities in America, which 
concerns chiefly a few of the European plants common to these countries. Eirst, there 
are m Labrador, or on the Rocky Mountains, or White Mountains of New Hampshire, a 
certain number of European plants found nowhere else in the American continent. They 
are
