The Plant-Life of Hare Island off the coast of West Greenland. 261 
Fig. 10 gives an illustration of such а “herb-mat.” Predominant 
are Erigeron uniflorus, Oxyria, Equisetum arvense, Polygonum vivi- 
parum and Pirola grandiflora. Common are Triselum spicatum, Poa 
pratensis, Stellaria longipes, Cerastium alpinum, С. trigynum, Arabis 
alpina, Drabae, Potentilla nivea, Saxifragae, Pedicularis spp., Campa- 
nula rotundifolia, and lastly, scarcer or rare Arnica alpina, Taraxacum 
croceum, Antennaria alpina, A. glabrata, Veronica alpina, Sibbaldia pro- 
cumbens and Potentilla alpestris. 
The shrubs Salix glauca, Empetrum and Cassiope are also quite 
common here, but the formation is marked by the occurrence of 
herbs. Salix forms small patches consisting of a few individuals 
which grow closely together, but the soil is always seen between 
the more or less prostrate branches, and willow-copses are totally 
wanting on the island.
