or mixed with Agropyron repens. Extensive stands of
Bromus inermis are also found at Mikligarður, Eyjafjarð-
arsýsla, N-Iceland (probably dating from the war); Flat-
eyri, Isafjarðarsýsla, NW-Iceland (probably also dating
from the war); and on Bessastaðahólmi ytri at Bessa-
staðir, Gullbringusýsla, SW-Iceland. It is spreading on the
sand plains in Mýrdalur, Vestur-Skaftafellssýsla, SE-Ice-
land; inside a forestry fence at Vaglir, Suður-Þingeyjar-
sýsla, N-Iceland; and on sandy soil at Þingvellir, Árnes-
sýsla, SW-Iceland, where it is spreading into birch shrub.
In addition it has been recorded at Akureyri, N-Iceland
(after 1944); Seyðisfjörður, E-Iceland (1954), Hamar in
Hamarsfjörður, Suður-Múlasýsla, E-Iceland (1954); Höfn,
Austur-Skaftafellssýsla, SE-Iceland (1961); Isafjörður (the
city), NW-Iceland (1962); Siglufjörður, N-Iceland (1963);
Sauðárkrókur, Skagafjarðarsýsla, N-Iceland (1964); and
Vestmannaeyjar, S-Iceland (1966). It is to be expected
that this species will continue to spread from cultivation
in many areas during the next decades.

In Stefánsson (1948) the following statement on this
species is found (translated from the Icelandic): “Found
in several places in SW, S and N-Iceland. A foreign species
that is probably about to become permanently established
(in Svartárdalur, N-Iceland).” This species has been con-
tinually spreading out from gardens in the last decades in
Reykjavík; Mosfellssveit, Kjósarsýsla; Hafnarfjörður and
Keflavík, Gullbringusýsla, all localities in SW-Iceland; Sel-
foss, Hveragerði, Laugarvatn, Eyrarbakki, Stokkseyri, all
in Árnessýsla, S-Iceland; Vestmannaeyjar (the city), S-Ice-
land; Akranes, W-Iceland; Borgarnes, Mýrasýsla, W-Iceland;
Isafjörður and Patreksfjörður, Isafjarðarsýsla, NW-Ice-
land; Blönduós, Húnavatnssýsla, N-Iceland; Sauðárkrókur,
Skagafjarðarsýsla, N-Iceland; and Siglufjörður and Akur-
eyri, N-Iceland. In 1960 Lamium aTbum was found grow-
ing outside gardens at no less than 47 farms in Skaga-
fjarðarsýsla and Húnavatnssýsla alone, both N-Iceland
