In the south‐western part of Iceland virus‐like symptoms were observed on various plant species asBetula pubescens, Epilobium angustifolium, Geranium syhatkum, Lupinusnootkatensis, Paeonia peregrina, Sorbus ancuparia, Stachys betonicifolia.A mechanically transmissible virus could be isolated fromE. angustifolium.By investigating the host range and by immunoelectron‐microscopical and serological methods the isolated virus was identified as turnip mosaic potyvirus. Thus, a plant pathogenic virus was detected in Iceland for the first time.
