staðahólmur ytri), in a lake, containing a dense colony
of eider ducks, Bromus inermis and Hordeum jubatum
grow in abundance and have probably grown there for
several years. This is the only place where H. jubatum
has become established outside gardens, but it is of irre-
gular occurrence near chicken houses and newly seeded
grassfields. Agropyron repens, Senecio vulgaris and Matri-
caria matricarioides also grow on the island.
Reykjalundur. Kjósarsýsla. An army camp existed in
this plase in the period 1940—1945, but later a chicken
and pig farm was operated here for a long time. In the
period 1955—1956 Einar M. Jónsson recorded 39 species
of foreign plants from this place. Some of these were
rare such as Silene cucubálus, Melandrium noctiflorum,
Potentilla norvegica, Echium vulgare, Anchusa arvensis
and Rudbeckia laciniata.
In Akureyri only plants recorded in the years
1964—1966 are listed. Altogether 60—70 species of fo-
reign plants have been recorded from Akureyri in the
present century. In Neskaupstaður, E-Iceland, observa-
tions were chiefly made in 1949, but in the remainder of
the localities in 1960—1966. Three of the localities are
schools, i.e. Hólar, Skagafjarðarsýsla, N-Iceland (an old
agricultural school); Skógaskóli, Rangárvallasýsla, S-Ice-
land (16 years old) and Laugarvatn, Árnessýsla, S-Iceland
(the school dates from 1928 and is situated in a geo-
thermal area. Later a small village has risen here). The
remaining localities are all towns, with the exception of
Hornafjörður, which is a farming comunity with a vil-
lage (Höfn).
