17 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. 2. Lamium album (ljósatvítönn) (fig. 2). 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 2
