Brown, R. N. R., The Flora of Prince Charles Foreland, 

 Spitzbergen. (Trans. Proc. bot. Soc. of Edinburgh, XXIII. IV. 

 p. 313-320. 1908.) 



Enumeration of plants collected in expeditions 1906—1907, with 

 notes on physical features of Prince Charles Foreland the most 

 westerly island of Spitzbergen archipelago. The island is about 

 55 miles long and 6 miles broad and separated from Spitzbergen 

 by a straight 2—8 miles wide; the whole island is mountainous 

 rising to Mount Monaco (1140 metres), and many Valleys contain 

 glaciers. A raised beach \— < l miles broad encircles the island and 

 is clear of snow from June to September, and Vegetation is also 

 good on peatbogs and talus at foot of hüls; the west coast has a 

 more luxuriant Vegetation than the east. The author notes the rapid 

 flowering of Arctic plants, also that certain American species present 

 in Greenland have not been found here. The new species added 

 increase the flora of the Foreland from 29 to 55 species. but this 

 is regarded as still incomplete because several species common in 

 Spitzbergen (with 200 spp. of vascular plants) have not been col- 

 lected. The list of species found is given. W. G. Smith.
