or adhering to wood pieces, Laminaria blades, or other drifting 
things. The iact that all the 3 Irish species and the Norwegian 
one grow near the open sea, or in the western part of islands 
facing the Atlantic, seems to tell of the same thing. Both 
Eriocaulon, Sisyrinchium . and Spiranthes are water or moss 
plants, and their seeds may easily be transported to the ocean 
with ri vers and streams. 
If this explanation is the right one — which neither can be 
proved nor disproved — the occurence of Ranunculus Cym- 
balaria in Norway must be regarded as a first colon isation 
in Europe. As the plant was found in lots of individuals and 
ripens its frnit on Asmal, it is possible that the species will get 
a much wider destribution in the future. The possibility is 
hovvever not precluded that the plant also has other habitats in 
Scandinavia or western Europe. And svstematical investigations 
in distriets as yet little known, might therefore perhaps give good 
results.
