Ostenfeld, C. H., Plants collected during the first Thule 

 Expedition. (Medd. om Grönland. LI. p. 371—381. 1915.) 



During the first Thule Expedition in 1912 to the nothernmost 

 parts of Greenland Mr. P. Freuchen collected a number of 

 plants of which the author gives a list together with some critical 

 notes. The localities from where the plants were brought home are 

 situated between 81° 15' and 82° 15' Lat. N. and between 22° and 38° 

 W. Long. No species is new to the Greenland flora, but 28 of 

 the species were not found before in the northern part of N. W. 

 Greenland, the flora of which no has 55 species, a number 

 which undoubtedly will be increased b}^ future explorations. 



Among the species the following are of special interest as 

 regard the geographical distribution of arctic plants: Pleiiropogon 

 Sabinel, Erigeron compositus, Taraxacunt Phyrnatocarpuni , Poa ab- 

 breviata, Melandrium affina, M. triflorum and Saxifraga flagellaris.

A promontor}'^ in the north of Scotland, between the Moray 

 Firth and Findhorn Bay, was rapidly invaded by sand at the 

 close of the IS^'i centur}^ and a considerable tract of fertile farm- 

 land was buried. The invasion still proceeds, and the authors descri- 

 bes with the aid of useful sketch-maps, the present Vegetation. A 

 small marginal area shows salt-marsh with Statice maritima domi- 

 nant. The main mass consists of shifting dunes with Ammophila 

 arenaria^ fixed dunes {Carex arenaria ^ Cailtinaj etc.), and dune 

 marshes v/ith a succession towards water communities in a number 

 of small lakes. Some of the shifting dunes are extensive and exhibit 

 striking features of dune phenomena. These sands present great 

 variations as regards stability of the substratum, with rapid chan- 

 ges of habitat from place to place. This has its reflection in the 

 large number of plant communities recorded, and in the manifold
