S. jacobaea L. var. nudus Weston sensu Van der Meijden is not recorded from Sylt and the Danish Wadden islands, as GREMMEN & KREMERS (1971) and VAN DER MEIJDEN (1976) mentioned. They confused records of Senecio dunensis (without author), being formerly S. vulgaris L.f. dunensis Knuth (S. vulgaris subsp. denticulatus (O. F. Müller) Sell) with those of S. dunensis Dum. (S. jacobaea L. var. nudus Weston).
