Records of attached seaweeds new to the flora of Sweden and records of very rare or otherwise interesting species from the west coast arc presented with notes on their morphology, distribution and ecology. Platoma bairdii, Schmitzia hiscockiana, Sphaerococcus coronopijblius, Cryptopleura ramosa, Hypo ff los.rnm hypoglossoides, Delamarea attenuata, Sargassum muticum and Protomonostroma undulatum are additions to the flora recorded during the last twenty years. Twenty-four very rare or otherwise interesting species are also listed. Some species previously considered as rare, and some of the new finds, were found to be common. Proposed explanations for the increasing amount of records are: ( 1) methodological reasons (diving vs. dredging); (2) increased number of visits to wave-exposed habitats; (3) the occurrence of favourable years resulting in higher abundances. Several species are considered as genuinely rare in their entire geographical distribution area, while some have their present northern distribution boundary at the Swedish west coast.
