DR. HOOKER ON THE DISTRIBUTION OF ARCTIC PLANTS.

Eriophorum capitatum. 
poly stachy urn. 
Alopecurus alpinus. 
Deyeuxia Lapponica. 
Deschampsia caespitosa (East Greenland only). 
Phippsia algida. 
Colpodium latifolium 
Poa flexuosa. 
pratensis. 
nemoralis. 
Festuca ovina. 
Of the above, Saxifraga oppositifolia is probably the most ubiquitous, and may be 
sidered the commonest and most arctic flowering plant. 
The following are also inhabitants of all the five arctic areas, but do not usually a 
such high latitudes as the foregoing : 
Ranunculus Lapponicus. 
Draba rupestris. 
Viola palustris. 
Honkeneya peploides. 
Epilobium angustifolium. 
alpinum. 
Polemonium caeruleum,and vars. (East Green- 
land only,) 
Pedicularis Lapponica. 
Armeria vulgaris. 
Betula nana. 
Salix lanata. 
Hippuris vulgaris, 
Artemisia borealis. 
Vaccinium uliginosum 
Vitis-idaea. 
Ledum palustre. 
Pyrola rotundifolia. 
glauca. 
alpestris. 
Luzula campestris. 
Carex vesicaria. 
Eriophorum vaginatum 
Atropis maritima. 
The absence of Gentiana and Primula in these lists is very unaccountable, seeing how 
abundant and very alpine they are on the Alps and Himalaya, and Gentiana on the South 
American Cordilleras also. 
The few remaining plants, which are all very northern, and almost or wholly confined 
to the arctic zone, are the following, f indicates those species absolutely peculiar ; ft the 
only peculiar genus. 
Ranunculus Pallasii. 
hyperboreus. 
Trollius Asiaticus.
