(1948), Löve (1945) records Linaria vulgaris. Thus the
number of foreign species found growing in a wild state
in Iceland and recorded for the first time in the period
1900—1948, is 117, of which 23 may now be considered
permanently established, but of course it is often a mat-
ter of judgement, whether a species should be called per-
manently established (or naturalized) or not. Some of the
above mentioned species may be considerably older in the
country than the records indicate, as for example Ceras-
tium glomeratum and Allium oberaceum. Most of the spe-
cies seem to have spread mainly during the last 25 years.
