Greenl. pi., p. 470). Hart's specimens of his Arenaria groenlandica 

 in the Kew herbarium, doubtless belong to A. Eossii, and in all 

 probability the same is the case with Greely's plant under the same 

 name, which is said to be sterile the same as Hart's. 



Occurrence. Grinnell Land, Discovery Harbour (Hart !). South 

 coast: Harbour Fjord, in the Barren Vallies (2390) and in valley at the 

 western entrance (2454). Goose Fjord, valley inside the Castle. West 

 coast: Reindeer Cove, Lands End (2849). 



Distribution: Arctic American Archipelago, Arctic coast of the 

 continent. Rocky Mountains, Land of the Chukches, Spitsbergen.

Fenzl has in Ledebour, 1. c, I, p. 347—350, referred to the 

 Arenaria verna of Linnaeus (further defined by Bartling) a great 

 many forms and species distinguished by different authors, and some 

 botanists who have had an arctic flora for object, have followed him, as 

 I think with good reason. Indeed, the large-flowered main form of the 

 plant, such as grows in the Alps of the Europe and Asia, is not found 

 in arctic regions, but there are, in the first-mentioned parts other forms 

 which connect it with the arctic ones. Knowing such a series of in- 

 termediate forms to exist, I have thought it best to adopt the above 

 name for the species. 



The Ellesmereland specimens generally are best referred to var. 

 rubella, (Wahlenb.), some may be referred to var. hirta, (Wormskj.), and 

 some others may perhaps represent the var. propinqua, (Richards.). 

 It is, however, quite impossible to draw distinct lines between these 

 forms. In the driest stations the plant appears as var. riihella, generally 

 even smaller and with shorter peduncles as the figure of Wahlenberg 

 shows. This is the most common form. In somewhat moister and richer
