A multivariate morphometric study of Senecio paludosus L. from Central and Western Europe, with additional material from other neighbouring areas is presented. Three subspecies, namely S. paludosus L. subsp. paludosus, S. paludosus subsp. angustifolius Holub and S. paludosus subsp. lanatus Holub are recognised.
Principal coordinate analysis confirmed good morphological separation of the above-mentioned taxa using quantitative and qualitative characters with only a few intermediates. The recognition of S. paludosus subsp. bohemicus (Tausch) Celak. as a separate subspecies was not confirmed.
