362 Dr. Hooxer’s Account of a 
Thunberg of Japan, and Pursh of Pennsylvania. In the north 
of Europe it is found in Nordland (Wahlenberg) ; and I have 
reason to think, that the R. affinis of Brown and Hooker (in 
Parry’s Ist and 2d Voyages) will prove but to be slight varie- 
ties of this plant. 
Since only one specimen of R. auricomus exists in Captain 
Sabine’s collection, it is probably rare in Greenland. In the 
temperate parts of Europe it inhabits wooded places. 
3. R. glacialis. 
A native of high mountains, both in the north and south of 
Europe ; of the Pyrenees, Switzerland, Hungary and Austria. 
Not found in Britain. It occurs on the Lapland Alps, but not - 
on those in the neighbourhood of the sea, nor below the higher 
summits of the mountains. Captain Scoresby gathered it in 
East Greenland (it is incorrectly called R. nivalis by Hooker 
in Scoresby’s East Coast of West Greenland) ; and this is pro- 
bably the extent of its western range; for it was not seen by 
Dr. Richardson in Arctic America, nor was it found in Cap- 
tain Parry’s or Captain Ross’s expeditions, except it be the 
plant that is mentioned by Mr. Brown as “ Ranunculus sul- 
phureus forte, vel glacialis species e fragmentis non determi- 
nanda.” Br. in Ross’s Voy.

4. P. nudicaule. 
Confined to the northern and principally to the alpine 
regions of Europe, Asia and America. Upon the tops of the 
central range of mountains in Norway, called the Dover Chain, 
as stated by Professor C. Schmidt in De Candolle. In Eastern 
Siberia ;
